学术报告题目:Big Data Applications for Traffic Management Systems


学术报告简介:


Vehicle positioning and speed data generated by individual vehicles have always been considered as big data for its size and complexity. It has been utilized to generate traffic information. We want to take one step further to incorporate individual vehicle data into traffic control, gradually replacing the role of the existing traffic surveillance systems as the dominant source of traffic data. To prepare for such a paradigm shift, one needs to overcome some key institutional barriers, in particular, the privacy issue. A Highway Voting System (HVS) is proposed to address this issue in which drivers provide link- and/or path-based vehicle data to the traffic management system in the form of "votes" in order to receive favorable service from traffic control. The proposed HVS offers a platform that links data from individual vehicles directly with traffic control. In the system, traffic control responds to voting vehicles in a way similar to the current system responding to priority vehicles and providing the requested services accordingly. Strategies to entice drivers into "voting" so as to increase the market penetration level under all traffic conditions are discussed. Examples are given to demonstrate the impact of the proposed system on algorithm development and traffic control.
