The Impact Analysis of the Urban Highway Traffic Incidents on FCD

Future traffic information (i.e. speed, traveling time) can be predicted through analyzing former floating car data (FCD). However, a significant deviation of the forecast usually occurs due to traffic incidents. In order to study the impact on traffic caused by incidents, this article sampled the incidents of the highways of a certain area in Beijing to analyze the alterations of FCD and the impact of the occuring time, location, and the local traffic condition on the characteristics of the traffic incidents. Both qualitative and quantitative analyses were applied to analyze the speed decline of the floating car caused by the incidents, impact road length, and impact duration of the incidents. The article concluded that local traffic conditions plays a key role in speed decline and the occurring time effects impact duration and speed decline.
