description: N,N-dibromo-p-toluenesulfonamide (TsNBr2) has been found to be a new reagent for bromination of aromatic compounds. The reaction is extremely fast which goes into completion instantaneously at ambient temperature to produce exclusively the corresponding polybrominated product. This procedure is applicable to various phenols, anisole and anilines to give corresponding polybrominated compound as single product in excellent yield.

description: Recycling of Nd–Fe–B magnets is an ongoing challenge regarding circular economy. State‐of‐the‐art magnet production methods, such as hot deformation, have limitations with respect to direct recycling of magnet scrap particles that differ from pristine melt‐spun Nd–Fe–B powder. Recent work has shown that a combination of presintering by field‐assisted sintering technology/spark plasma sintering (FAST/SPS) and hot deformation by flash spark plasma sintering (flash SPS) has the potential to directly produce Nd–Fe–B magnets from 100% scrap material. Both processes have the capability to adjust and monitor process parameters closely, resulting in recycled magnets with properties similar to commercial magnets but made directly from crushed and recycled Nd–Fe–B powder that partially or completely replaces pristine melt‐spun Nd–Fe–B powder. Herein, a systematic study is done inserting recycled magnet particles into a flash SPS deformed magnet, considering the effects of different weight percentages of scrap material of varied particle size fractions. In some cases, coercivity HcJ of >1400 kAm⁻¹ and remanence Br of 1.1 T can be achieved with 20 wt% scrap material. The relationship between particle size fraction, oxygen uptake, and percentage of recyclate in a final magnet are all explored and discussed with respect to magnets made from pristine material.

description: Objectives: Transport-related accidents remain the largest single cause of death among people aged 15 to 29 in the European Union, and despite the decrease in number of fatalities from 1990 onwards they remain a significant public health problem. The aim of this article was to analyze the long-term trends and patterns of transport-related fatalities, identify the anatomic distribution of most significant injuries in different road users, and identify the primary populations at risk of transport-related death in Austria between 1980 and 2013.Methods: Data on transport-related fatalities based on death certificates were obtained from Statistics Austria for the analyzed period. Crude and age-standardized mortality rates per 100,000 were calculated and broken down by age, gender, and month of death, and the anatomic distribution of most significant injuries were identified. Potential years of life lost before age 75 (PYLL-75) were used as a measure of public health impact.Results: A total of 39,709 transport-related fatalities were identified for the studied years; 74% were males and the mean age was 42.1 years (range 0–103). A decrease in the number of fatalities (from 2018 in 1980 to 554 in 2012), mortality rates (from 26 in 1980 to 7 in 2012), and PYLL-75 (from 68,960 in 1980 to 14,931 in 2012) was observed. Introduction of major prevention milestones (compulsory use of seat belts or child restraints) may have contributed to this decrease. Men 16–24 years old were at the highest risk of transport-related death. Pedestrian victims were more likely to be women and car drivers and motorcyclists were more often men. Most fatal transport accidents occurred between the months of May and October and prevailingly in towns of fewer than 20,000 inhabitants. Injuries to the head were the most significant injuries in all user groups (>50% of cases in all road user types). Reduced mortality rates could translate into higher prevalence of long-term disabilities in survivors of transport accidents.Conclusions: Despite the decreasing trend observed, transport-related fatalities remain a serious public health issue in Austria. An increase in the mortality of motor vehicle drivers warrants more preventive action in this group. Further research is needed on other outcomes of transport accidents such as long-term disabilities to elucidate the true public health burden of transport accidents.

description: I perioden 1999-2002 var Odense officielt Danmarks Nationale Cykelby. Odense Kommune fik tildelt halvdelen af budgettet på 20 mio. kr. som tilskud fra Trafikministeriet og Vejdirektoratet. Projektet omfattede fysiske forbedringer, regelændringer og kampagnemæssige aktiviteter. Der blev fokuseret på aktiviteter inden for følgende områder: Cyklisters fremkommelighed, bedre cykelparkering, driftskvalitet, imageplejende og aktionsprægede aktiviteter samt cyklisters trafikale adfærd. Odense Cykelby har betydet mere end 20 procent flere cykelture, svarende til over 35 mio. nye cykelture i projektperioden 1999-2002. Antallet af skader blandt cyklister i flerpartsuheld er faldet med 20 procent. Projektet har medført 33 mio. kr. i sparede sundhedsudgifter, og samlet givet 2131 flere leveår til odensianerne. En panelundersøgelse viser, at Odense opfattes som en god by for cyklister, og øget cykling er forbundet med øget trivsel og velvære.

description: Som på andre områder er der på cykeltrafik- og cykelpolitikområdet fremkommet værktøjer, der muliggør en sammenligning af forholdene og indsatserne i forskellige byer. I visse lande er man kommet ganske langt med sammenlignelige data for et stort antal byer. Også internationalt kan man nu, takket være BYPAD (BicYcle Policy AuDit), sammenligne status for cykelpolitikken i byer fra forskellige lande. De forskellige metoder benytter varierende grad en blanding af konkrete data og subjektive vurderinger. Mange gør brug af selv-avaluering. Paperet giver en oversigt over de forskellige metoder og et mindre udpluk af de opnåede resultater.

Year: 2004

description: Novalog er et EU-projekt, der har til formål at afdække logistiske kompetencer i EU, samt nye medlemslande. Projektet er en videreudbygning af projektet: Innotrans, som alene har fokuseret på transportsiden. Novalog er startet i 2001 og afsluttes i oktober i år. Traditionelt bliver transport og logistik brugt næsten synonymt og mange godstransportvirksomheder er i dag i meget høj grad – full-service logistikleverandører. No-valog sætter netop fokus på dette område ved at se på logistiske funktioner indenfor en række områder. Herunder f.eks. distributionsplanlægning, lageroperationer, samt udvik-ling af logistikkoncepter såvel i transport, logistik-som produktionsvirksomheder. Klarlægningen af de logistiske kompetencer sker indenfor 4 hovedområder: • Eksisterende forhold. Dette har til formål at beskrive de enkelte landes status ved at benytte officiel statistisk materiale, officielle jobdefinitioner, samt uddannelsesprogrammer. Igennem denne beskrivelse vises bl.a., hvordan logistikken er indplaceret i de enkelte landes forretningsbevidsthed. • Kompetencer. Ud fra interviews med virksomheder, der sammenholdes med input fra andre kilder dannes der et billede af, hvilke logistiske funktioner der udføres i virksomheder, samt hvordan disse er organiseret. Organiseringen er tæt knyttet til virksomhedens størrelse og struktur, dog uden det er muligt at opstille klare retningslinier for, hvordan den ”optimale” organisering er. • Uddannelser med fokus på logistik. En overordnet gennemgang af uddannelserne i de europæiske lande viser, indenfor hvilke områder, der udbydes logistiskuddannelser, samt hvilket fokus de har. Dette vil give virksomheder mulighed for at søge på tværs af landegrænser efter uddannelsesmuligheder for medarbejdere. • Innovative cases. I de forskellige lande findes flere nye og innovative angrebsmetoder i uddannelsen, der med fordel kan udbredes til andre lande. Disse innovative cases optræder som et inspirationskatalog, hvor virksomheder og uddannelsesinstitutioner kan få eksempler på, hvordan en kreativ uddannelse kan gennemføres. De udvalgte uddannelser tager alle udgangspunkt i logistikken, men det vil ikke hin-dre, at metoder og systemer kan overføres til andre områder med succes.

Persontransport i bil - en total social kendsgerning

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 1997

description: Indlægget bygger på resultater og konklusioner fra både en kvantitativ og kvalitativ undersøgelse af en gruppe Horsensfamiliers brug af deres bil. Begge undersøgelser er blevet udarbejdet i forbindelse med "Nye veje frem - projekt om familie, energi og transport" og blandt de 52 familier, som har meldt sig til projektet. De giver således et billede af det konkrete transportmønster, men også deltagernes holdninger til transport. Projektet er blevet til i et samarbejde mellem Danmarks Naturfredningsforening, Horsens Kommune og Trafikministeriet. Det er en opfølgning på målsætningerne i "Trafik 2005" om at nedbringe energiforbruget til persontransport. Projektet strækker sig over perioden april 1996 - september 1997 og finansieres af Trafikpuljen 1995. Projektet, som fungerer som et forsøg, skal undersøge, hvad der skal til for at ændre på en uhensigtsmæssig udnyttelse af bilen alene ved holdningspåvirkning (til forskel fra direkte indblanding som afgifter o.lign.). Det skal ligeledes give et billede af de muligheder, familier har for at omlægge deres transportmønstre, og hvilke hindringer, som vil stille sig i vejen for en sådan omlægning. Projektets mål er derfor ikke at få familierne til helt at undlade at bruge bilen, men derimod at motivere dem til at gøre det med omtanke. Et vigtigt resultat af projektet er, at flere af deltagerfamilierne har ændret deres transportvaner i løbet af kampagneperioden i retning af at køre færre korte ture. Det skal her understreges, at familierne er forskellige, og det giver forskelle i brug af bilen, hvilket igen giver forskelle i mulighederne for at ændre transporten i en mere miljørigtig retning. Forskellene kan først og fremmest forklares ud fra familietype og aktivitetsmønstre. Familietyperne er primært defineret på baggrund af børnenes alder, da det har vist sig, at forskelle i transportmønster ofte kan forklares udfra familiens sammensætning. Den kvalitative analyse viser, at der også er andre faktorer, som spiller ind, når det gælder holdninger til transport og valg af transportmiddel til de daglige ture. Det har blandt andet været muligt at konstatere, at kørselsomfanget i høj grad er betinget af, hvilken situation (alder, uddannelse, arbejde/karriere etc.) familien befinder sig i og familiemedlemmernes indbyrdes relationer.

description: Diskussionen om virkemidler til at nedbringe trafikken CO2-udsendelse bærer præg af, at de to sider ikke lytter til hinandens argumenter. ”Bilsiden” lægger vægt på bilen som nødvendig del af hverdagen og tager afstand fra mere bilbeskatning og mere kontrol. ”Miljøsiden” peger på, at mageligheden må have en grænse, støtter fordyrelse af brug af bil og ser klimaet som et alvorligt problem. Bilen er folkelig, og anses i praksis for vigtigere end at være bæredygtig. CO2 er absolut akademisk. Debatten kunne vinde i kvalitet og dermed have øgede chancer for at føre til resultater, hvis miljøsiden i højere grad fokuserede på mål og fordele end på midler. Herudover er der behov for at sammenhængen mellem transport og velstand drages ind i debatten, og at det gøres respektabelt at være magelig. En svaghed ved en sådan debat er, at den risikerer at modparterne når til enighed, hvilket gør den uegnet til de elektroniske medier.

description: A practical total synthesis of racemic nyasol (7) was explored. The α-hydroxyketo compound 3 was prepared from commercially available starting materials in two steps. Chelation-controlled reduction of the α-hydroxyketo compound 3 with Zn(BH4)2 gave the anti-1,2-diol compound 4 as the major product (anti/syn = 11.5:1). Stereospecific elimination reaction of a 1,3-cyclic thionocarbonate intermediate (5) exclusively yielded the Z-alkene compound 6. Our total synthesis is very concise (seven steps), uses commercially available starting materials, and offers good overall yield (40%).

description: Discrete time competitive-cooperative neural networks are investigated using a decomposition approach that embeds a competitive-cooperative neural network into an augmented cooperative system by splitting the synaptic weights into inhibitory and excitatory groups. This allows for the use of the basic order-preserving property of cooperative systems to study the original network system. Properties such as quasi-ordering, positive invariance, dissipativity, convergence, and stability of the networks are analyzed, yielding detailed characterization of the system trajectory bounds and decay rates. A simple yet effective procedure is also proposed for the design of a network with prescribed equilibria and guaranteed basin of attraction and decay rate.

description: The biogeochemical gradients that will develop across the interface between a highly alkaline cementitious geological disposal facility for intermediate level radioactive waste and the geosphere are poorly understood. In addition, there is a paucity of information about the microorganisms that may populate these environments and their role in biomineralization, gas consumption and generation, metal cycling, and on radionuclide speciation and solubility. In this study, we investigated the phylogenetic diversity of indigenous microbial communities and their potential for alkaline metal reduction in samples collected from a natural analogue for cementitious radioactive waste repositories, the hyperalkaline Allas Springs (pH up to 11.9), Troodos Mountains, Cyprus. The site is situated within an ophiolitic complex of ultrabasic rocks that are undergoing active low-temperature serpentinization, which results in hyperalkaline conditions. 16S rRNA cloning and sequencing showed that phylogenetically diverse microbial communities exist in this natural high pH environment, including Hydrogenophaga species. This indicates that alkali-tolerant hydrogen-oxidizing microorganisms could potentially colonize an alkaline geological repository, which is predicted to be rich in molecular H2, as a result of processes including steel corrosion and cellulose biodegradation within the wastes. Moreover, microbial metal reduction was confirmed at alkaline pH in this study by enrichment microcosms and by pure cultures of bacterial isolates affiliated to the Paenibacillus and Alkaliphilus genera. Overall, these data show that a diverse range of microbiological processes can occur in high pH environments, consistent with those expected during the geodisposal of intermediate level waste. Many of these, including gas metabolism and metal reduction, have clear implications for the long-term geological disposal of radioactive waste.

description: This paper analyzes the stability of a class of discrete linear multidimensional (MD) systems, whose solutions are path dependent and may not be uniquely specified by initial conditions. Based on the concept of solvable Lie algebra and a new comparison principle, it presents a simple necessary and sufficient condition for exponential stability of the MD systems in terms of the spectral radius of the system matrices. This extends a previous result based on the pairwise commutativity of the system matrices. A numerical example is given to illustrate the present result.

description: Transportrådet har gennemført en survey der skal kortlægge danskernes flyvaner. Surveyen var lagt an på at skaffe meget detaljerede oplysninger om de konkrete flyrejser: Hvad var formålet med flyrejsen, hvilken type billet rejste interviewpersonen på, hvorfor valgte de at flyve og havde de overvejet alternativer til at flyve, var der mellemlandinger på turen, hvor længe var de hjemmefra, hvor tit har de fløjet det sidste år eller de sidste fem år, har de tilbagevendende erhvervsrejser, kombinerede de erhvervsrejse med privatrejse, osv. Surveyen er derfor et stærkt supplement til de eksisterende danske og internationale opgørelser af flytrafikken. Undersøgelsen blev sat i gang, fordi man ikke kender ret meget til danskernes flyvaner. Vi ved, gennem den officielle statistik, at flytrafikken er steget voldsomt gennem de sidste mange år - faktisk med en højere rate end vejtrafikken. Paperet præsenterer de første delresultater af surveyen.

Regional Patterns of Urban Development and Travel Behaviour
Creators: name: Næss, Petter

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2004

description: A study of residential location and transport in three provincial counties in Denmark shows that residential location affects the travel behavior of households, and that this affect is still apparent when various socioeconomic characteristics of the households are taken into consideration. The study also shows, that the spatial distribution or geographical spread as well as the size of the different urban centers in the three counties play a significant role in explaining the travel and transport behavior of individual households. Theoretical and empirical evidence from a recent study into the relationship between the residential location and distance to urban centers the Copenhagen metropolitan area shows that individuals emphasize choice rather than proximity to the urban centers for most travel purposes. Thus, as a result, the travel behaviour of households and individuals is primarily influenced by the location of the residence in relation to downtown Copenhagen, whereas the location of the residence in relation to lower-order centers with lower concentrations of facilities only to lesser degree has a bearing on the travel behaviour of households and individuals. The same influence of the distance to urban centers with the highest concentration of facilities seems to apply to households in three provincial counties of Denmark, but in contrast to the metropolitan area of Copenhagen, no single urban center in each of the three counties asserts enough of an influence on the travel behaviour to stand alone. Although cities like Holstebro in the county of Ringkoebing, and Aalborg in the county of North Jutland have a significant effect on travel behaviour, it seems that the location of the residence in relation to a conglomeration of 1st order urban centers in each of the provincial counties is needed to describe the relationship between residential location and regional patterns of urban development.

Hovedstadsregionen og Pendling – Verden vokser
Creators: name: Ege, Hans
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2004

description: Storbyregionerne får stigende betydning i nationernes og Europas udvikling, og de vokser i ud- strækning samt befolknings- og arbejdstal. Trafikmængder og trængsel øges, og der opstår behov for nye, hurtigere regionale trafikforbindelser, som ofte er meget bekostelige. Pendlingstrafikken er dominerende for udformningen af mange af disse forbindelser p gr a pendlingens koncentrerede afvikling, morgen og aften, og p gr a pendlernes stadigt voksende rejselængder. Pendlingen og pendlernes vilkår i trafiksystemet er under løbende forandring og samtidig afgørende forudsætninger for Hovedstadsregionens ”vækst, velfærd og miljø”. For såvel den regionale trafik- plan som regionplanen, den regionale erhvervsstrategi, Øresundsregionens udvikling, den offentlige, administrative struktur og trafikdriften er pendlingens udvikling og vilkår en afgørende forudsætning og samtidig en dynamisk påvirkningsmulighed. Det er derfor væsentligt, at der tilvejebringes et godt vidensgrundlag i form af data og analyser for pendlingens status, udvikling og påvirkningsmulighed. På den baggrund har HUR iværksat en op- gradering af viden og værktøjer på pendlingsområdet. Og pendlingsanalyser indgår som vægtigt beslutningsgrundlag i et voksende antal plan- og strategiområder.

Publisher: name: Swinburne
Year: 2024

description: This note presents a performance analysis of periodic nonlinear sampled-data controllers for the rejection of Lp specific and uniform disturbances. Earlier results on the performance of linear periodic controllers are extended to nonlinear controllers. For a given periodic controller, a time invariant controller is constructed which in general gives strictly better Lp disturbance rejection performance than the periodic controller.

description: The biogeochemical gradients that will develop across the interface between a highly alkaline cementitious geological disposal facility for intermediate level radioactive waste and the geosphere are poorly understood. In addition, there is a paucity of information about the microorganisms that may populate these environments and their role in biomineralisation, gas consumption and generation, metal cycling, and on radionuclide speciation and solubility. In this study, we investigated the phylogenetic diversity of indigenous microbial communities and their potential for alkaline metal reduction in samples collected from a natural analogue for cementitious radioactive waste repositories, the hyperalkaline Allas Springs (pH up to 11.9), Troodos Mountains, Cyprus. The site is situated within an ophiolitic complex of ultrabasic rocks that are undergoing active low-temperature serpentinisation, which results in hyperalkaline conditions. 16S rRNA cloning and sequencing showed that phylogenetically diverse microbial communities exist in this natural high pH environment, including Hydrogenophaga species. This indicates that alkali-tolerant hydrogen-oxidizing microorganisms could potentially colonise an alkaline geological repository, which is predicted to be rich in molecular H2, as a result of processes including steel corrosion and cellulose biodegradation within the wastes. Moreover, microbial metal reduction was confirmed at alkaline pH in this study by enrichment microcosms and by pure cultures of bacterial isolates affiliated to the Paenibacillus and Alkaliphilus genera. Overall, these data show that a diverse range of microbiological processes can occur in high pH environments, consistent with those expected during the geodisposal of intermediate level waste. Many of these, including gas metabolism and metal reduction, have clear implications for the long-term geological disposal of radioactive waste.

Publisher: name: Swinburne
Year: 2024

description: In this paper, we consider the design of 2D (two-dimensional) FIR (finite impulse response) multirate filter banks. For a given 2D FIR analysis filter bank, we design a 2D FIR synthesis filter bank to minimize the reconstruction error of the filter banks such that the worst case energy gain between the input and the reconstruction error is below a prescribed bound. Our solution is formulated in terms of a set of linear matrix inequalities (LMIs) which can be directly computed by Matlab.

description: ABSTRACTSurfactant formulations used in chemical dispersing agents are derived from the same functional components used in numerous household products such as dishwashing soaps and laundry detergents. During the Deep Water Horizon (DWH) oil spill response, a significant volume of chemical dispersant was deployed, causing members of the public and the media to question the role of chemical dispersant (Corexit 9500) usage in mitigating oil spill effects. Consequently, laboratory tests were conducted by regulatory agencies to further evaluate and substantiate the existing aquatic toxicity of Corexit dispersants. To help put dispersant toxicity in context, two independent accredited labs were commissioned to conduct parallel studies that compared the acute toxicity of Corexit 9500 to common household cleaning agents. The results indicate that the acute toxicity of Corexit 9500 to marine aquatic organism is either within the median range or less toxic than the household cleaning agents tested. The median LC50 value for Corexit 9500 exposures to Americamysis bahia was 42.5 mg/L (four products were less toxic and four products were more toxic); whereas, the median LC50 value for Corexit 9500 exposures to Menidia beryllina was 73.1 mg/L (one product was less toxic and seven products were more toxic).
CykelBus´´'ter projektet i Århus - resultater, konklusioner og perspektiver

description: Regeringens trafikpolitiske regegørelse fra dec 1995 har som mål, at 4% af persontransportarbejdet skal flyttes fra bil til cykel. Metoderne til at opnå en sådan ændring opdeles ofte i pisk- og gulerodsmetoder. Piskemetoderne er velkendte i form at afgifter på biler og benzin mv. Gulerodsmetoderne er derimod mindre udviklede. Kan man få bilister til at opgive bilen og istedet bruge cykel eller bus ved at motivere dem med forskellige fordele? Dette spørgsmål er forsøgt besvaret i CykelBus’ter projektet. CykelBus’ter projektet i Århus er gennemført af Århus kommune i samarbejde med Miljøstyrelsen i perioden 1. maj 1995 til 31. marts 1996 . Projektet er evalueret af Trafikforskningsgruppen ved Aalborg Universitet med økonomisk støtte fra Transportrådet. Projektets formål var at undersøge, i hvilket omfang, man gennem en massiv påvirkningsindsats overfor motiverede personer kan flytte persontrafik fra bil til cykel og bus. Som målgruppe blev der i projektet valgt personer, som kørte i bil til arbejde i Århus centrum hver dag, og som boede i en afstand på mellem 2-8 km fra centrum - denne afstand blev valgt, fordi cyklen på disse afstande er et godt alternativ til bilen. Gennem en massiv hvervekampagne, hvor 1700 personer meldte sig som deltagere, blev projektets 173 deltagerne fundet. De blev lovet en ny cykel med diverse udstyr til 4.000 kr, som de efter projektåret kunne købe til 1000 kr. Yderligere fik de et gratis buskort. Til gengæld skulle de - i projektperioden - love at lade bilen stå i så høj grad som muligt og istedet bruge cykel eller bus, samt deltage i et forskningsprojekt. CykelBus’ter projektet er tidligere præsenteret på Trafikdagene i 1995 og 1996. Papers fra disse præsentationer beskriver projektdesign og evalueringsprogrammet. Endvidere præsenteres resultaterne fra kilometeropgørelsen og dele af kørebogsanalysen. Interesserede læsere henvises til konferencerapporterne fra 1995 og 1996. I dette paper præsenteres resultaterne fra spørgeskemaundersøgelserne, helbredscheck og dele af kørebogsanalysen. Endvidere er der forsøgt opstillet en sammenfattende konklusion på projektet, herunder hvordan resultaterne kan generaliseres dels til hele Århus, dels til hele landet.

description: Pot and field experiments were conducted to investigate the effects of soil amendments (cow manure, rice straw, zeolite, dicalcium phosphate) on the growth and metal uptake (Cd, Zn) of maize (Zea mays) grown in Cd/Zn contaminated soil. The addition of cow manure and rice straw significantly increased the dry biomass, shoot and root length, and grain yield of maize when compared with the control. In pot study, cow manure, rice straw, and dicalcium phosphate all proved effective in reducing Cd and Zn concentrations in shoots and roots. Cd and Zn concentrations in the grains of maize grown in field study plots with cow manure and dicalcium phosphate amendments to highly contaminated soil (Cd 36.5 mg kg−1 and Zn 1520.8 mg kg−1) conformed to acceptable standards for animal feed. Additionally both cow manure and dicalcium phosphate amendments resulted in the significant decrease of Cd and Zn concentrations in shoots of maize.
How to enhance walking and cycling instead of short car trips

description: The EU-DG VII (Urban Sector) project WALCYNG, which has the goal to enhance walking and cycling instead of short car trips, has taken the non-profit-marketing concept, as basis for the research work. According to this concept, changes in road user behaviour shall be achieved by improving preconditions for walking and cycling in the physical sense (product policy); by improving the image of walking and cycling (communication policy); and by giving the road users who do not yet walk and cycle incentives to make them try these modes (incentive policy). All this should be done on basis of extensive knowledge about the status quo about the needs, wishes and perspectives of different groups of road users (information policy). To start with, one should focus on those, who already walk and cycle and on those who shall be convinced to start walking and cycling instead of using the car for short trips. WALCYNG was divided into 12 different work packages. The first seven work packages covered the information and product policy part. The last work packages dealt with communication and incentive policy. In the paper some of the results will be presented.
