Abstract


In order to adapt to the rapid economic development and urban sprawl, the construction of the tunnel is an important way to solve the traffic problems in some city, Xiamen tunnel group. However, because the tunnel is a semi-enclosed special space in the event of an accident, it is likely to cause traffic congestion, even paralysis of the entire road network, therefore the need to implement effective security management and traffic control measures to ease the pressure of urban tunnel traffic. Xiamen City Tunnel as the background, a summary analysis of the theory and practice of the organization of the city tunnel traffic system to extract the traffic tunnel under the city tunnel traffic characteristics of the tunnel and its road network reliability calculation method, the conventional conditions program, including the management and control programs, abnormal traffic flow evacuation and rescue organizations of the city the tunnel road traffic organization and management methods. The main work of this paper are as follows: (1) from the point of view of the whole road network and the entire region to study the reliability of the regional road network of the city tunnel influencing factors, given the quantitative calculation of tunnel reliability mainly with connectivity reliability and smooth reliability, important prerequisite for the tunnel road traffic organization and management to provide basis for decision making. (2) in urban tunnels at home and abroad has been a model of road traffic organization based on the analysis, combined with the city tunnel traffic driving traffic characteristics, summarizes the macroscopic transport organizations and the microscopic transport organizations combining conventional tunnel traffic organization, the main tunnel entrances, convergence, intersection, basic sections and other microscopic traffic organization. (3) through the analysis of the abnormal situation in the city tunnel traffic driving characteristics, extracted from the tunnel area of ??influence within the traffic guidance and management control mode. For tunnel the internal lane blocked and full lane blocked summarizes the tunnel staff, the the evacuation organization and rescue vehicles of the vehicle rescue organization program. And tunnel affect traffic in the area within the ease traffic organization and control management measures proposed regional impact within three shunt control mode, including a set of three control points and three evacuation road, signal control and non-signal control two control modes, The objective of maximizing the evacuation efficiency. (4) design Xiamen roundabout roads wear Convention Center tunnel road traffic organization and management programs, and the use of VISSIM micro-simulation software for optimization and simulation evaluation, a tunnel control the intersection to ease the organization.
