Aim – GLP-1 and glucagon dual receptor agonists are under clinical
development for a range of metabolic conditions including as type 2
diabetes and obesity. The cardiovascular actions of GLP-1 and glucagon
receptor agonism are well studied, however less is known about their
combination. The aim of this study was to explore the haemodynamic
effects of dual agonism at the GLP-1 and glucagon receptor. Methods –
Healthy male participants attended a series of randomised,
saline-controlled intravenous infusion studies using glucagon [low]
(25 ng/kg/min), glucagon [high] (50 ng/kg/min), exenatide (loading
dose 50 ng/min for 30 minutes then 25 ng/min) and exenatide:glucagon
co-infusion for 120 minutes (Part A, glucagon dose-ranging study), or 60
minutes (Part B, dual-agonism study). Results – In Part A (n=7, 25±7
years), glucagon dose-dependently increased heart rate by 3 bpm with
glucagon [low] (p=0.407) and 11 bpm with glucagon [high] (95%
CI 4-17 bpm, p<0.01). In Part B (n=12, 25±3 years), exenatide
increased heart rate by 4 bpm (95% CI 2-6 bpm, p<0.001).
Glucagon [low] increased heart rate by 4 bpm (95% CI 1-7 bpm,
p<0.001). Co-infusion increased heart rate by 7 bpm (95% CI
4-9 bpm, p<0.001). There were no differences in stroke volume,
cardiac output, blood pressure, or heart rate variability. Conclusion –
With the exception of an increase in heart rate, no concerning
haemodynamic signals have been detected in studies with GLP-1 and
glucagon dual receptor agonists. Our data are consistent with these
findings, showing dual agonism acutely increases heart rate in healthy
male participants.
A decision-making machine learning based approach for earthquake early warning Mukesh Gupta1
Authors: Gupta Mukesh , Kumar Brijesh
Published: June 2024

Earthquake early warning systems have become vital for minimizing damage
from seismic events. However, their automated detection capabilities
need strengthening to provide real-time alerts. Current algorithms have
limitations in identification of P-waves and magnitude estimation,
impacting warning lead times. Additionally, existing single-algorithm
dependent systems are prone to errors. There is a need for standardized
practices to optimally select and combine algorithms. Machine learning
and artificial intelligence show promise to make detection more robust.
Models trained on diverse seismological data can learn complex patterns
to detect emergent P-waves earlier and refine magnitude assessment.
However, research exploring such data driven approaches within early
warning systems is limited. This study aims to address this research gap
and strengthen automated detection capabilities. It proposes a machine
learning model integrating multiple existing algorithms using a novel
prioritization framework. Performance is evaluated on real earthquake
datasets through simulations vis-à-vis single algorithms. By developing
an optimized multi-algorithm framework, this study seeks to improve
warning lead times and reliability. The model is designed considering
operational requirements of early warning systems. Comparison of results
with past methods helps evaluate contributions to the field. Overall,
the research strives to enhance seismic hazard mitigation through more
efficient automated detection in early warning networks.
Simple-to-complex crater transition for the Uranian satellites Ariel and Miranda
Authors: Borrelli Madison E , Bierson Carver J. , O'Rourke Joseph Ghilarducci
Published: June 2024

The latest decadal survey identified the Uranus system as the
highest-priority new target for a NASA Flagship mission. Ariel and
Miranda are potential ocean worlds with evidence of resurfacing
potentially due to past elevated heat flow. Learning about the geologic
histories of these icy moons is important for understanding the
potential for life in the outer solar system. Using limited data
acquired by the Voyager 2 spacecraft, we explore open questions about
the surfaces of Uranian satellites to gain a better understanding of
their evolutionary histories. In this work, we update the estimates of
Ariel and Miranda’s simple-to-complex transition diameters, which have
not yet been measured using modern GIS techniques and reprocessed data.
The simple-to-complex transition diameter is a value used on many worlds
to infer the composition of the surface. For the Uranian satellites,
this value was last estimated shortly after the Voyager 2 flyby with a
dataset of 18 craters. We use reprocessed topography from more than 100
craters to estimate a simple-to-complex transition diameter on Ariel of
~26 km, consistent with an icy surface composition. We
place a lower limit of ~49 km on the transition diameter
for Miranda, where we cannot identify any complex craters. We also
estimate the relative and absolute ages of terrains on Ariel and
Miranda. Our results agree with recent studies showing that they likely
experienced relatively recent resurfacing. Finally, we suggest imaging
requirements for the future mission to Uranus to answer outstanding
questions about Ariel and Miranda.

Recent developments in molecular genetic testing methods (e.g. next-generation sequencing [NGS]-panels) largely accelerated the process of finding the most appropriate targeted therapeutic intervention for cancer patients based on molecularly targetable genetic alterations. In Hungary, a centralized approval system following the recommendation of the National Molecular Tumor Board was launched for the coordination of all aspects of comprehensive genetic profiling (CGP) including patient selection and therapy reimbursement.
Aim: The study aims to evaluate the clinical benefit of CGP in our Comprehensive Cancer Center
Methods and patients: CGP was introduced into our routine clinical practice in 2021. An NGS-based large (> 500 genes) gene panel was used for cases where molecular genetic testing was approved by the National Molecular Tumor Board. From 2021 until August 2023 163 cases were tested. The majority of them were ECOG 0–1 patients with advanced-stage diseases, histologically rare cancer, or cancers with unknown primary tumours.
Results: Seventy-four cases (74 of 163, 45%) had clinically relevant genetic alterations. In 34 patients, the identified variants represented an indication for an approved therapy (approved by the Hungarian authorities, on-label indication), while in 40 cases the recommended therapy did not have an approved indication in Hungary for certain tumour types, but off-label indication could be recommended. Based on our CGP results, 24 patients (24/163; 14.7%) received targeted therapy. Treatment duration was between 1 and 60 months. In total 14 (14/163; 8.5% of the tested cases) patients had a positive clinical response (objective response or stable disease) and were treated for more than 16 weeks.
Interpretation: NGS-based CGP was successfully introduced in our institution and a significant number of patients benefited from comprehensive genetic tests. Our preliminary results can serve as the starting point of Drug Rediscovery Protocol (DRUP) studies.

Published: June 2024

Background and purpose: Current follow-up protocols for adolescent idiopathic scoliosis (AIS) are based on consensus and consist of regular full-spine radiographs to monitor curve progression and surgical complications. Consensus exists to avoid inappropriate use of radiographs in children. It is unknown whether a standard radiologic follow-up (S-FU) approach is necessary or if a patient-empowered follow-up (PE-FU) approach can reduce the number of radiographs without treatment consequences.Methods and analyses: A nationwide multicenter pragmatic randomized preference trial was designed for 3 follow-up subgroups (pre-treatment, post-brace, post-surgery) to compare PE-FU and S-FU. 812 patients with AIS (age 10–18 years) will be included in the randomized trial or preference cohorts. Primary outcome is the proportion of radiographs with a treatment consequence for each subgroup. Secondary outcomes consist of the proportion of patients with delayed initiation of treatment due to non-routine radiographic follow-up, radiation exposure, societal costs, positive predictive value, and interrelation of clinical assessment, quality of life, and parameters for initiation of treatment during follow-up. Outcomes will be analyzed using linear mixed-effects models, adjusted for relevant baseline covariates, and are based on intention-to-treat principle. Study summary: (i) a national, multicenter pragmatic randomized trial addressing the optimal frequency of radiographic follow-up in patients with AIS; (ii) first study that includes patient-empowered follow-up; (iii) an inclusive study with 3 follow-up subgroups and few exclusion criteria representative for clinical reality; (iv) preference cohorts alongside to amplify generalizability; (v) first study conducting an economic evaluation comparing both follow-up approaches.
Mechanisms of Immune Dysregulation Induced by Pesticide Exposure and their Implications for Cancer: A Systematic Review
Authors: DM* Benvegnú
Published: June 2024

The inappropriate use of pesticides contaminates natural resources and has consequences for human health. Evidence of immune dysregulation caused by pesticides has been presented, but studies linking exposure to these substances with immune dysregulation and its relationship to cancer are scarce. This study systematically reviews the published literature that addresses the topic of immune dysregulation and cancer and its relationship to pesticide exposure. Studies developed in vitro cell culture and in vivo experimental animals and human exposure data were included. The results show that pesticide exposure has a relevant impact on immune dysfunction, negatively affecting immune system cells and cytokine production in innate and adaptive responses. The main consequences reported were suppression of the Th1 response, induction of the Th2 response, cellular balance dysregulation, and cytokine production changes. All reported events are related to the occurrence of immunosuppression. This dysregulation is paramount for cancer progression and may lead to a worse prognosis in chronically exposed populations. These findings also point to the need for further studies, primarily focused on human exposure.

Studying the effectiveness of project solutions using the transport modeling
Authors:   Lviv communal enterprise “Lvivavtodor”, Plesak Stepan
Published: June 2024

One of the factors that lead to an increase in congestion on the road network is the growth of motorization levels in the city. Under such conditions, the number of private vehicles on city streets is increasing as delays at intersections and queues. As a result, the passage of the intersection is delayed, as drivers are forced to wait longer for their turn. When reconstructing a street or road, it is proposed to change the traffic management, the number of lanes and the configuration of some intersections to solve the problems described above. However, after the project is implemented, traffic flows are mostly redistributed, and the proposed changes may not be effective. It is imperative to conduct transport modeling, which allows checking the effectiveness of decisions and adjusting the project in the early stages, but not after implementation, to prevent the negative impact of such situations. When performing transport modeling, unnecessary investments that may arise after implementing the project can be avoided, or the feasibility of its implementation can be checked. The object of research is a section of the road network located in a settlement. It is worth noting that all approaches to intersections have high traffic volumes, which should be taken into account when creating project documentation. This article presents a design solution that includes reconfiguring the intersection, increasing the number of lanes, and conducting transport microscopic modeling of the existing and projected conditions to determine the effectiveness of changing the traffic management on the studied section of the road network. According to the results of the microscopic modeling, delays and queues on the approaches to the intersection have been reduced, which indicates that the decision was correct. PTV VISSIM software was used to perform transport modeling. After testing the simulation model and analyzing the results, it is possible to assess the impact of design decisions on the road network and, if necessary, make adjustments.

The problems of traffic management in large cities are complicated as the increase in traffic volume far exceeds the road network capacity. It leads to saturation of the road network, which negatively affects its functioning. This article analyzes the state of the art of improving the quality of road traffic by predicting the size of traffic after the implementation of traffic management measures. While the issue of modeling traffic flow parameters based on technological factors has been sufficiently studied, the problems of considering the human factor need to be clarified. The object of study is traffic flow on the city's road network. The criteria used by drivers to compare the characteristics of alternative traffic routes were identified based on the field study results. Based on the data obtained, the parameters of alternative routes that drivers choose when driving on the road network are formed. According to the survey results, the most significant factor is the minimum mileage along the route. Deviations from the shortest route were determined to determine the patterns of distribution of correspondence of non-route vehicles along alternative routes. It made it possible to define the distribution of transport correspondence along alternative routes. Since the process under consideration is probabilistic, the law of distribution of a random variable was determined. After having determined the law of distribution of a random variable for the data obtained, the calculations showed that the change in the random variable is well described by the gamma distribution. It was determined that the share of transport correspondence that will be carried on them decreases as the length of the route deviates from the shortest one. The obtained results make it possible to predict road network congestion by modeling the distribution of traffic flows. In further research, it would be advisable to analyze the distribution of transport correspondence by other criteria.
Problems of the human factor in transport systems
Authors:   Lviv Polytechnic National University, Mygal Galyna
Published: June 2024

Transport accident statistics and practical safety results indicate that technological solutions cannot ensure the viability (safety, sustainability, reliability and efficiency) of complex systems and structures without addressing human factors. This problem is especially acute for transport systems as highly complex technological and social structures aimed at ensuring the efficiency and safety of an entire sphere of human life. In transportation systems and technologies, the human factor plays a critical role. The successful operation of transport systems requires consideration of the human factor at all levels – starting from the development, design and planning of systems and technologies, training and education to the involvement of society in decision-making processes. Therefore, it is essential to develop the concept of human factor management and analyze the main problems in transport systems associated with the human factor to improve the safety, reliability and efficiency of their functioning. The article is devoted to the analysis of the human factor problem in transport systems and the search for solutions to manage it. The purpose of the article is to analyze the main problems in transport systems associated with the human factor and to develop the concept of human factor management for further search for solutions to improve the safety and reliability of transport systems. A set of instruments was proposed in the study to achieve the goal and solve the set tasks. Problems connected to the human factor in transport systems were analyzed. The main directions for solving problems with the influence of the human factor on the safety of transport systems were systematized. The main principles, models and ways of developing the concept of managing the human factor problem in complex systems, including transport, were outlined. A systematization of the risk management strategy was proposed. A matrix for the relationship between risk management strategies and approaches to managing the safety of complex systems was proposed. A new look at the principle of adaptive ergonomics as an implementation of the tolerance strategy was proposed, and applying the principle of adaptive ergonomics to transport systems was considered. The main motivation of the work is to attract the attention of the scientific and educational community to the problem of human factor and the need to use the concept of human factor management in the educational process to improve the general safety culture in society.

Authors:   Lviv Polytechnic National University, Chudiiovych Bohdanna , Tiurdo Nazar ,   Lviv Polytechnic National University
Published: June 2024

According to traffic accident statistics, the main causes are violations of traffic rules. Based on scientific research, it is clear that the main reason for these events is the drivers' incorrect assessment of the road situation and their inadequate response. Assessing road conditions depends on drivers' qualifications, skills, work experience, reaction time, and other physiological factors. The functional state of drivers is important to consider. It reflects their ability to work reliably and affects both fatigue levels and how fatigue builds up. Factors that impact decision-making speed and quality are crucial when evaluating the risks of the transportation process, particularly those associated with human behavior. This study investigates the safety of freight transportation for drivers, road users, third parties, and the environment. The study focuses on road traffic characteristics in mountainous conditions at high altitudes. The study aims to analyze how drivers' performance is affected while navigating challenging sections of mountain roads in the Ukrainian Carpathians. Four different routes will be examined. The research will provide graphic analysis of the results. It will show the main patterns of changes in drivers' functional state based on the route's complexity. The research aims to analyze indicators of drivers' functional state and their impact on their performance reliability. It allows for a more detailed evaluation of transport routes and planning of truck drivers' work and rest schedules on suburban routes.

The downstream petroleum products distribution is beset with significant challenges due to ageing pipeline infrastructure, pipeline vandalism and other logistical constraints. These challenges have given rise to soaring pump prices of premium motor spirit (PMS), product shortages and unavailability across some locations in Nigeria. Thus, deploying alternative transport modes for PMS distribution is explored to improve product distribution efficiency. The decision to combine inland waterway transport (instead of pipeline network) and road transport modes would activate the intrinsic advantages inherent in the multimodal transport system. However, the efficiency outcome of using multi-modes may be eroded if the multimodal transport operators compete (instead of collaborating) in service provisions. This research investigated cost efficiency in cooperative collaboration among multimodal transport carriers. We proposed collaboration among six multimodal transport operators. The aim of encouraging such a large-scale coalition (S) is the expectation that costs emanating from their joint operation would be reduced. We applied the Shapley value cost allocation method to distribute the costs of operation and profit to the collaborators. After the analysis, we observed that the unit cost for coalition S1 was reduced by N17.16 (5.10 %) million naira. Similarly, we observed respective reductions in unit costs for coalitions S2, …, S10. We observed a reduction in cost by N107.84 million naira, which represents a 6.15 % reduction in total unit cost for the multimodal transportation carriers. Thus, the observed cost efficiency represents savings due to distribution chain efficiency if the multimodal transport carriers collaborate to improve product availability. Working as a coalition would offset PMS pump price variation attributable to distribution chain inefficiency.

The purpose of the study is to increase the unit train load efficiency at the elevators having their shunting locomotives. The research is based on the analysis of time series, methods of organizing the operational work of railways, and methods of traction calculations. The paper considers the problem of organizing shunting work at elevators when loading grain unit trains. Critical wear and tear of shunting locomotives in railway transport of general use necessitates using their locomotives at the elevators. As a result of the research, the dependence of the duration of shunting and cargo operations on the number of cars in the unit train and on other factors was established. Various types of shunting locomotives were compared. Based on the analysis, it was established that it is advisable to use four-axle shunting diesel locomotives with hydraulic transmission for shunting work at the elevators. The traction force of such locomotives is sufficient to deliver empty cars to the elevator at a speed of 14–15 km/h. Loaded cars can be removed at a speed of 14–15 km/h with a slope of the connecting track up to 2–5 ‰. With greater slopes, the removal of loaded cars should be performed at a speed of 5 km/h. The main factor affecting the duration of shunting operations is the distance of delivery and removal of cars. Technologies for loading the grain unit trains at the elevators, providing for the presence of cars at the loading stations for two and three days, have also been developed. The main factor affecting the duration of unit train loading is the staff of locomotive assembly teams. The originality of the study is in obtaining the dependence between the parameters of the technical support of the elevators and the duration of the presence of cars in the connecting station – elevator’s siding system. The practical value of the paper is that its results can be used in the design of the reconstruction of existing and construction of new elevators, as well as in the estimation of costs associated with various loading technologies of the unit trains for the corresponding sidings.

Authors: Boodoo Curtis
Published: June 2024

Renewable energy solutions are vital for sustainable development, particularly in Small Island Developing States (SIDS) facing challenges related to fossil fuel dependence. This study examines the design, installation, and performance evaluation of an off-grid solar photovoltaic (PV) system. The system is located in a remote, forested region of Trinidad, providing electricity for wildlife rehabilitation efforts in a facility lacking conventional grid access. The research analyzes empirical data on system performance under humid tropical conditions, addressing practical challenges and highlighting the importance of accurate solar resource assessments for such environments. Financial analysis includes a detailed cost breakdown and calculation of the levelized cost of electricity (LCOE), providing insights into the economic feasibility of off-grid solar solutions. Results indicate significant discrepancies between simulated and actual performance, underscoring factors such as lower-than-anticipated solar irradiance and the impact of a constant nighttime energy load on battery cycling. Recommendations are provided to optimize future off-grid PV installations for similar applications in Trinidad and Tobago and the broader CARICOM region.

Ein umfassendes Wissen über das Verkehrsgeschehen dient als wesentliche Grundlage für politische und wirtschaftliche Entscheidungen und für Modellierungen und Prognosen. Viele Institutionen und Organisationen sind auf die Daten dieser Art angewiesen. Der Aufwand für Datenbeschafung und Erstellung der Statistiken steht in einem extrem günstigen Verhältnis zu etwaigen Projekt- und Folgekosten. Die Optimierung der Erhebungsmethode kann Qualität und Aussagekraft einer Statistik und damit ihren Nutzen deutlich steigern.
Future of Urban Logistics

Seine aktive Rolle im Umweltschutz ist dem Öffentlichen Personennahverkehr (ÖPNV) nicht fremd. Seit
Jahrzehnten ist der Umweltvorteil des Verkehrs mit Bussen und Bahnen bekannt, und die ÖPNV-Branche
wirbt auch mit diesem Vorteil gegenüber dem PKW-Verkehr um Kunden und politische Förderung. In
einer ideellen Partnerschaft mit Fußgänger-, Rad- und Taxiverkehr wurde der Begriff des „Umweltverbun-
des“ geprägt. Doch was ist daraus geworden – in einer Zeit, in der das Ziel des Umweltschutzes um das
Ziel des Klimaschutzes erweitert wurde?
Nachhaltigkeit und Logistik
Authors: Haasis Hans-Dietrich , Mackenthun Feliks , Nestler Steffen , Nobel Thomas
Published: June 2024

Die Logistikwirtschaft in Deutschland verfolgt in unterschiedlicher Umsetzungsintensität Nachhaltigkeitsbestrebungen. Das Thema Grüne Logistik gewinnt in diesem Kontext zunehmend an Bedeutung und vollzieht eine Entwicklung hin zu einem umfassenden Nachhaltigkeitsansatz. Dieser beinhaltet drei zentrale Säulen (Ökologie, Ökonomie und Soziales). Lag der Fokus der Grünen Logistik seither auf der Ökologie und der Ökonomie, so kann gegenwärtig eine zunehmende Berücksichtigung der sozialen Komponente beobachtet werden. Gestiegene Anforderungen seitens der Endkonsumenten und Verlader an nachhaltigere Prozesse sind ebenfalls Treiber dieser „grüneren“ Entwicklung.
Ausbau der Eisenbahninfrastruktur in der Region Frankfurt RheinMain
Authors: Busch Thomas , Forst Peter , Becker Josef
Published: June 2024

Im Rhein-Main-Verkehrsverbund (RMV) fahren weit über 700 Mio. Fahrgäste jährlich. Zwei Drittel der Verkehrsleistung werden im regionalen Schienenverkehr erbracht. Damit die prognostizierten Verkehrszuwächse gewonnen werden können, muss das Leistungsangebot auf der Schiene weiter ausgebaut werden. Durch die hohe Auslastung des Schienennetzes in der Region mit Fern- und Nahverkehr sind jedoch schon heute die Fahrplanangebote nur mit Qualitätseinbußen realisierbar. Ein nachhaltiger Ausbau der Schieneninfrastruktur ist daher für die Zukunftsfähigkeit des öffentlichen Verkehrssystems unerlässlich.
Steigende Energiepreise und ihre Wirkung auf planerische Strategien
Authors: Altenburg Sven , Peter Marcus
Published: June 2024

In der Verkehrsplanung wird die Robustheit vorhandener Strukturen gegenüber deutlich gestiegenen Energiepreisen nur selten in Szenarien untersucht. Im Rahmen eines BMBF-geförderten Forschungsprojektes wurden die Auswirkungen höherer Energiepreise auf die räumliche Entwicklung sowie das Verkehrsverhalten modellhaft abgebildet und in ein Planspiel integriert. In diesem Planspiel haben Entscheidungsträger experimentelle Strategiepfade auf Basis von Modellergebnissen entwickelt. Die Notwendigkeit solcher Preisszenarien wird in diesem Artikel diskutiert und vor dem Hintergrund der Projektergebnisse reflektiert.

City 2.e - Das Elektroauto in stark verdichteten Stadtquartieren
Authors: Riedel Veronique , Schwedes Oliver
Published: June 2024

Der öfentliche Raum in Städten ist stark begrenzt – die meisten PKW-Besitzer/innen parken jedoch als „Laternenparker“ im öfentlichen Straßenraum. Um diese Gruppe für die Nutzung von Elektrofahrzeugen zu gewinnen, ist unter anderem eine zuverlässige, leistungsfähige und bedarfsorientierte Ladeinfrastruktur notwendig. Im Verbundprojekt City 2.e wurde ein Konzept für eine öfentliche und halböfentliche Ladeinfrastruktur erarbeitet. Das Fachgebiet Integrierte Verkehrsplanung (IVP) der Technischen Universität Berlin untersuchte dazu das Verkehrs- und Mobilitätsverhalten dieser Nutzergruppe.
Zulassungsprozesse für Fahrzeuge in Deutschland
Authors: Fricke Hartmut , Siegmann Jürgen , Winner Hermann
Published: June 2024

Alle Akteure im System Bahn bedauern seit geraumer Zeit die zunehmenden Verzögerungen in den Zulassungsprozessen von Schienenfahrzeugen. Die Zulassungsprozesse für Flugzeuge und Automobile verlaufen dagegen scheinbar reibungslos und eizient. Daher befasst sich die beginnende dreiteilige Artikelreihe mit dem Vergleich der Systeme, um hieraus, so weit erkennbar, Lernprozesse anzustoßen und verbleibende Schwachstellen aufzudecken. – Teil 1 behandelt die Systemunterschiede und die Zulassungsprozesse für Straßenfahrzeuge.
Steuer- oder Nutzerfinanzierung der Straßen?
Authors: Kossak Andreas
Published: June 2024

KFZ-bezogene Steuern machen in Deutschland einen beträchtlichen Anteil an den gesamten Steuereinnahmen aus. Die Mineralölsteuer, jetzt „Energiesteuer“, mit rund 39 Mrd. EUR und die Fahrzeugsteuer mit rd. 8,5 Mrd. EUR als Hauptquellen summieren sich auf deutlich mehr als das Doppelte der Nettoausgaben aller Aufgabenträger für das Straßenwesen. Nach deutschem Recht sind dies allerdings „allgemeine Steuern“, die dem „Nonafektationsprinzip“ unterliegen: Ihre Zweckbindung (ganz oder teilweise) zur Nutzerinanzierung der Straßeninfrastruktur ist möglich, aber nicht „zugriffssicher“. Der Beitrag zeigt, dass der schlechte Zustand der Straßeninfrastruktur in Deutschland maßgeblich auf die Konsequenzen daraus in der politischen Wirklichkeit zurückzuführen ist.

Lörrach banks on electric mobility
Authors: Lüers Arne , Wegner-Sänger Christine , Fessler Alexander
Published: June 2024

Increasing traic volumes represent a great challenge for the town of Lörrach. Situated in the immediate vicinity of Basel, Lörrach is subject to commuter and shopping traic. It is thus essential to ind new concepts and break new ground in terms of sustainable mobility. This is why, in early 2013, the town developed a mobility master plan setting targets and proposing measures concerning traic policy. Taking some of the car traic load of the town by promoting non-motorized traic and local public transport is the top priority. As for the promotion of environment-friendly alternatives, the enhancement of electric mobility is an important part of the master plan.

Self-driving cars are certainly in vogue. They are one of those technological developments that analysts reckon will have great market potential across the world. But what do vehicles actually need to make their independent way through the streets of the world? How far have we come? And how quickly are we going to have to get used to swarms of “robot cars”? These are some of the questions International Transportation asked Dr. Martin Birkner, Marketing Manager Automotive Sector at Here, Nokia’s mapping service.
Success factors for meta-search engines in online travel distribution
Authors: Eisenkopf Alexander , Haas Christopher
Published: June 2024

The importance of digital distribution in the travel industry is strongly increasing. Virtually any travel supplier or hotel is able to market its services directly on the Internet. Web platforms, like online travel agencies (OTAs), are taking over trading functions and facilitate sourcing information for the customer. In addition to trading platforms, meta-search engines like Kayak, Qixxit, momondo and Rome2Rio have evolved and are making the market more transparent. But what is so special about ‘Meta’? Can it work in the long run? Is Meta the most important, if not the only successful kind of business model in online travel distribution?
Smart-phone assisted travel assistance for passengers with reduced mobility
Authors: Schnieder Lars , Bischof Werner
Published: June 2024

Public transportation is a main factor for reliable mobility in urban and rural areas. Every user group and their specific requirements have to be considered during planning and realization of public transportation services. Hence public transport operators have to ensure a barrier-free public transportation service. Certainly this barrier-freeness still is not realized for every user group, due to the high complexity of public transportation systems. This article outlines an individual travel assistance application for smart phones which can be easily integrated into existing background systems of public transport operators.
