Authors: Li Miao Hua , Chen Shu Yan
Published: July 2014

Considering the fact that the amount of traffic incident data is rare compared to the large amount of normal traffic state data in the real word, we proposed an Automatic Incident Detection (AID) algorithm based on subsampling method. First, an improved subsampling method based on Edited Nearest Neighbor Rule (ENN) algorithm was used to reconstruct the training set to get a balanced dataset. Then, the Support Vector Machine (SVM) was adopted as a classifier to detect traffic incidents. The real traffic data collected from the I-880 freeway in American was used to build the model and test the performance of the proposed AID algorithm. In addition, we made a comparison of the detection performances between the AID algorithm obtained by the original training set and the one by the relatively balanced training set. The experimental results show that the proposed AID algorithm based on subsampling is suitable for imbalanced dataset and can obtain a better detection performance.

Published: July 2014

Corn bran was liquefied in phenol catalyzed by sulfuric acid at 120-180 °C. The liquefaction product (LCB) had groups of bound phenol and was considered as a precursor for synthesizing corn bran-based epoxy resin (LCBER). Namely, the phenolic OH groups of LCB reacted with epichlorohydrin under alkali condition. The structure and average molecular weights of LCB and LCBER in various reaction conditions were examined by FT-IR and GPC. Epoxy functionality was introduced to LCB and the extreme high molecular weight portion of LCBER-30 was obtained using LCB at 30 min as raw materials. LCBER was cured with polyamide-650 (PA-650) and the thermal and mechanical properties were evaluated. Comparing to the petroleum-based bisphenol-A type epoxy resin (DGEBA), LCBER presented higher adhesive shear strength and good thermal stability. These suggested that LCBER would be more suitable to glue biomass materials.

The relationship between the inside clearances and speeds of different types of vehicles is studied by mathematical statistics so as to establish a model of the relationship between inside clearances and speeds. Based on the collision deformation of different barrier types and the demand for the actual functions of the central strip, how to select the width of the central strip and the barrier type of the arterial highway of Xinjiang Corps is analyzed. According to the results, there is a linear relationship between inside clearances and speeds of vehicles; monolithic concrete barriers require a small width of the central strip and they are cheap on the whole and suitable for the corps area.

Published: July 2014

In analyzing the factors of traffic accident, the most important reasons are the influence of people, vehicles, roads, and the environment for traffic accident. Learning how to handle traffic accident normatively and identify the traffic accident correctly, is the important lesson need to be solved urgently. however, the current safety performance technical expertise work for accidental vehicles lack of according with relevant laws and regulations, scientific, adaptable, and workable identification norms. To solve this problem stated previously, this paper studies the technical identification standard of accident vehicles, which mainly introduces the effect, basis, selection of identification items of accidental vehicles safety performance technical identification, the content and demand of the identification process.

For positive effect traffic control means imposed on road traffic, collaborative optimization model were established, based on signal timing that can reflect the dynamic relationship between the intersection delay and intersection signal cycle, signal timing each lane including bus lanes, flow change and other parameters, Applying S-Paramics, the model were applied to a typical intersection in Dong Cheng district of Beijing, and regarded average speed and travel time as output. The simulation shows that compared with the single traffic control means, the model can decrease travel time and increase average speed.

The goal of this paper is to discuss whether building photovoltaic systems are suitable to be applied in Shanghai and Chenjiazhen in Chongming Island is taken as a typical example to be researched. Practical running data tested from building photovoltaic system of Chenjia Town ecological building and planning design of Building Integrated PV in Chenjia Town international ecological community were analysed. The research result was positive to use this energy system. Therefore, when new buildings in similar areas are planned to be designed, the designers should pay more attention to the applicable possibility of Building Integrated PV, which is beneficial to boost the use of renewable energy.

To explore travel options and travel equilibrium problem in urban traffic, the traditional research mainly focuses on the degree of association & mechanism between the travelers' choice behavior and influence factors. A generalized travel cost model is constructed based on the analysis of the main factors affecting travel behavior in the paper, the Nash equilibrium theory is introduced to analyze the best travel combinations between travel routes and transportation modes during to the travel cost matrix based on generalized travel cost, and Nash equilibrium cost matrix can be get. In this equilibrium condition, the generalized travel cost of each travel route and transportation mode becomes more balanced, which benefit distribution equilibrium; and no operator can obtain higher profits by changing the price strategy unilaterally, which ensure the stability of the cost matrix. The example and conclusion shows that the Nash equilibrium is existed in the analysis of cost in travel choice, and confirms that a better balanced travel can be obtained by adjusting the travel cost.

Published: July 2014

Vehicular flow in highway is inherently complex and development of microscopic models of vehicular flow has been a daunting task for researchers. This paper presents the use of Cellular automata (CA) micro simulation for modeling multi-lane traffic characteristics in highway, as well as considering the average speed difference (ASD) and lane-changing rules (LCR) in the CA model. Firstly, on the base of the Symmetric Two-Lane Cellular Automata (STCA) model, we analyzed the impact on traffic characteristics, through adjusting the maximum speed and lane-changing rules. Secondly, by the micro simulation, the relationships between speed and density in traffic flow were given considering the ASD and the LCR. The simulation results showed that, (a) the more obvious of speed dispersion, the more serious about speed declining, (b) the speed of overall traffic flow slowed down by 163% under extreme conditions, (c) the more reckless of lane-changing rule drivers used, the higher speed of traffic flow can reach.

Published: July 2014

Since the traffic safety of freeway interchange merging sections and the accidents occurred in this areas can not meet the requirement of statistical analysis, this paper employed traffic conflict technique to analyze the safety situation of freeway merging sections. The traffic data of vehicles through the merging sections are collected and analyzed. These data include the vehicle type, speed, time headway and others based on the features of individual vehicle. Then two methodologies are developed, the first is based on time to collision (TTC), which can calculate the rear-end conflict number, while the second is based on post encroachment time (PET), which can calculate the lane-change conflict number. The results show that these surrogate measures can quantitatively describe the rear-end conflict situation and lane-change conflict situation.
