    Abstract: This paper presents a methodology for using vehicle trajectory data to study the intradriver heterogeneity of driving behavior between the acceleration process and the deceleration process. Trajectory data were collected during peak hours on Dutch Motorway A2. Criteria were proposed for the selection of subtrajectories corresponding to both the acceleration and the deceleration processes of car-following. With the application of these subtrajectories to calibrate three types of models (the Helly model, the Gipps model, and the intelligent driver model), it was found that obvious intradriver heterogeneities existed in driving behaviors between the acceleration and deceleration processes of car-following: (a) the average response time of drivers in the acceleration process was longer than that in the deceleration process according to the prediction of the Helly and intelligent driver models; (b) drivers were apt to respond more intensively to surrounding traffic in the deceleration process than they did in the acceleration process; and (c) more than 65% of drivers involved in this study drove in obviously different styles between the acceleration and deceleration processes. Moreover, a compensation for the response delay from model parameters was observed, and all three models presented low robustness in predicting driving behaviors of one car-following process with the parameters optimized from the data of other car-following processes. This work not only provides insight into intradriver heterogeneity in car-following behaviors but also suggests some important criteria for car-following modeling.

    Scheduling of Feeder Vehicles for Intermodal Services for Special Events
    SAGE Publications ; 2011

    Abstract: During special events, shuttle services provided by a feeder bus system can be very useful for providing passengers access to the mass rapid transit system, especially passengers in suburban areas where regular transit service is not usually available. During Expo 2010 Shanghai in China, such shuttle services connected the major terminals and the expected locations of passenger generation. Because of constrained vehicle resources and the staggered characteristics of peak hours, the free time spans of regular vehicles were used to complete the fixed feeder timetables. An integer-linear programming model was developed to obtain the optimal schedules of the feeder vehicles, and an associated coordination mechanism was proposed to adjust the model-developed schedules to obtain feasible solutions. This model was applied to the feeder system in Jiading district during Expo 2010 Shanghai. The results showed that the temporary feeder system could serve Expo passengers with a relatively high level of service without causing evident degradation in the regular bus service.

    High-Speed Rail Project Development Processes in the United States and China

    Abstract: Amid increasing global economic competition, both the United States and China are investing in high-speed rail (HSR) as a national strategy to enhance their competitiveness. China is rapidly advancing by laying down HSR tracks, while the United States is deliberating the environmental, social, and economic implications of HSR development before embarking on actual construction. With the California High-Speed Rail Project and the Beijing–Shanghai Express Railway Project as case studies, this paper juxtaposes the HSR development processes concerning investment decisions, planning, and implementation in the United States and China and draws lessons informative to strategic infrastructure investments in both countries.
