Discussion on the Characters and Problems of the Slow Traffic System for the Technological Development Zone

Abstract

The traffic characters and conflicts are analyzed on the basis of including features of various kinds of traffic modes for the technological development zone. The investigation results reflects that travel time concentrated distribution and commuting is the mainly travel purpose. The proportion of slow traffic is more than 50% in the peak hours. The conflicts to the slow traffic mainly caused by public traffic and motor vehicle. Ignoring the slow traffic management, the lack of public participation and citizens do not satisfied the slow traffic environment and are the main problems for the slow system of technological development zone. Additionally, the strategies and contents of planning and design for slow traffic are suggested, which have good practical significance.

Construction and Simulation of Rear-End Conflicts Recognition Model Based on Improved TTC Algorithm

“…Gao et al [12] used two surrogate safety measures, TTC and DRAC, to study the rear-end conflict in the work zone based on the trajectory data of vehicles. Li et al [13] proposed a relationship model among TTC, vehicle deceleration rate and driver characteristics, and revised a conflict risk threshold for collisions in various regions of freeway based on the driver characteristics. Zheng et al [14] used the conflict rate as the evaluating measure, combining with the extreme value theory, then established the work zone traffic conflict risk measurement model.…”
