TY - JOUR PY - 2007// TI - Linear Model Based Expressway Traffic-Flow Wave Analysis on the Influence of Traffic Incidents and Intervention Process JO - Journal of Wuhan University of Technology (Transportation Science and Engineering) A1 - Wang, Jiangping A1 - Huang, Lan SP - 172 EP - 175 VL - 31 IS - 1 N2 - Owing to the influence of traffic incidents, natural expressway traffic flow will be influenced. In order to promote dissipation of traffic flow congestion or clog and reduce vehicle queue delay under the influence of traffic incidents, some intervention measures should be adopted in the upper reaches of the origin of traffic incidents. Based on hydrodynamic traffic flow wave theory, it is analyzed the interactive influence of traffic incidents and intervention measures on expressway traffic flow, established traffic flow wave speed model, traffic flow wave position models and corresponding time models under the interactive influence of intervention shock wave and concentration-wave, startup-wave and dissipation-wave result from traffic incidents and relieving diffluent intervention measures time model on the basis of linear model of speed related to traffic density. These models or critical parameters provide theoretical basis for effectively determining schemes to solve traffic incidents and quickly eliminating traffic congestion or clog.
