GPS/INSBased Intersection Turning of Autonomous Vehicle ZHU Yu-Xi, QU Chao, CHEN Hui Journal of Transportation Systems Engineering and Information Technology    2012, 12 (增1): 91-98.   Abstract （5768）      PDF （1130KB）（9826）       This paper introduces a method to realize automatic turning at intersections in urban environment based on the GPS/INS (global positioning system/inertial navigation system). It not only uses the GPS/INS to generate route network definition file, but obtains real time positioning and turning information. As the vehicle approaches the intersection, the paper utilizes waypoints which locate the end segment of the current road and the beginning segment of the next road to perform local path planning online by polynomial curve fitting. The preview follower control is used to make the vehicle following the trajectory planned to cross the intersection when secure for turning. As to the preview follower control method, the simulation of “vehicleroadcontroller” based on the Matlab/Simulink shows that the vehicle can follow the planned trajectory with smooth steering wheel angle curve which can be conducted by steering system. Finally, field test shows that by applying this method, the unmanned vehicle with EPS can turn autonomously at intersections.

Commuter’s Choice Behaviorof Travel Time and Travel Mode ZHUGe Cheng-Xiang, SHAO Chun-Fu, LI Xia, MENG Meng Journal of Transportation Systems Engineering and Information Technology    2012, 12 (2): 126-131.   Abstract （5141）      PDF （414KB）（3040）       With analysis of the joint choice features of travel time and travel mode, the paper develops two nested Logit (NL) models on commuters’ travel time and travel model choice behavior .The data from the 2005 Beijing household travel survey are used to estimate the two models by the BIOGEME. The structure of the NL model is identified by the inclusive value parameter, and the result reveals the travel timetravel mode model is more reasonable than the travel modetravel time model, which indicates that the commuters always choose the travel time at first and then consider the travel mode under the time constrain. Moreover, the parameters of travel timetravel mode model are calibrated and analyzed.

The paper analyzes the differences between the statistical data of transportation energy consumption in China and the international statistical caliber, and thinks that the data of private vehicle, motorcycle, low-speed vehicle (agricultural automobile) are lack in the statistics of China. It develops a calculation model of transportation energy consumption based on the vehicle driving and calibrates related parameters. The result shows that, based on the correction of international caliber, the transportation accounts for 60.1％ (36.4％ according to the domestic statistics) of the total petroleum end-use consumption, and the transportation accounts for 12.7％ (8.1％ according to the domestic statistics) of the total energy end-use consumption. The paper also compares the transportation energy consumption level of China with other developed countries, and finds that the energy consumption per capita and the transportation energy consumption proportion are relatively low in China, but increase rapidly in recent years.
