Embodiment Construction

[0067] Hereinafter, the present invention will be further explained in conjunction with the drawings.

[0068] This embodiment only figure 2 The four one-way sections marked 1, 2, 3, and 4 and the turn generated by section 1 are calculated. The traffic management measures involved in section 1 and section 3 include: bus lane (one), truck prohibition and congestion charging ; The management measures involved in Section 2 and Section 4 include: roadside parking and ban on trucks; traffic management measures existing at intersections include: prohibition of steering and green wave coordinated control. Such as figure 1 , figure 2 with image 3 As shown, an urban road network generalized right-of-way calculation method of the present invention considering comprehensive traffic management measures includes the following steps:

[0069] (1) Calculation of road section time impedance considering traffic management measures

[0070] This step also includes four steps: analysis of the basi...

Abstract

The invention discloses an urban road network generalized road right calculating method considering comprehensive traffic management measures. The method comprises road section time impedance calculation with traffic management measures being taken into consideration and intersection delay calculation under a traffic control strategy, and specifically comprises road section basic traffic capacity analysis, influence correction of the traffic management measures on road section traffic capacity, road section time impedance analysis and correction of the traffic management measures on road section time impedance; and intersection entrance road lane group division based on turning relation, lane group motor basic traffic capacity analysis, influence correction of the traffic management measures on lane group traffic capacity and intersection delay analysis for traffic assignment. The method can reflect independent road rights of different types of vehicles in an urban road network, can enable simulation and prediction results to be more accurate, quantifies difference of different traffic management strategy combination schemes and provides powerful support for planning of current urban traffic management and control and formulation of traffic policies.

Description

Technical field [0001] The invention belongs to the field of urban road traffic planning and management, and relates to a generalized road right calculation method for urban road networks considering comprehensive traffic management measures. Background technique [0002] With the advancement of my country's urbanization and the rapid growth of motorization, the contradiction between the supply and demand of urban road traffic has become increasingly serious, and traffic congestion has become the norm in large and medium-sized cities. [0003] Prioritizing the development of public transportation and improving the effectiveness of traffic management measures are the main methods for most cities in my country to alleviate the above-mentioned problems. Adjust the traffic travel structure through public transportation priority strategy, formulate traffic demand management plan to improve the rationality of travel demand, cooperate with traffic security management plan to improve the r...
