Embodiment
[0089] Select a certain city as an example analysis, in order to verify and evaluate the method of the present invention. The city has 141 existing bus lines with a total length of 2854km. The city's bus passenger flow is generally high. According to the traffic survey of the city's residents, more than 40% of the road sections have a peak-hour passenger flow of more than 6,000 people. Urban road conditions are good, and most bus corridors have more than three lanes in one direction.
[0090] According to the city's existing road conditions and the OD volume of bus trips, select roads with a bus passenger flow of more than 6,000 passengers in peak hours in the city to form a set L, select roads with a number of lanes greater than or equal to 3 to form a set M, and calculate the set L and The intersection N of the set M, the roads in the set N are planned as the initial bus-only lanes, and the initial bus-only lanes are obtained as image 3As shown in the figure, each bus-onl...

The invention provides a planning and network distribution method of exclusive lanes for urban public transportation and belongs to the field of the urban public transportation, aiming at solving the problems that an existing public transportation exclusive lane is low in service level and a public transportation trip proportion is influenced. The planning and network distribution method comprises the following steps: determining an urban public transportation passenger flow and an public transportation operation speed, establishing a requirement set of the exclusive lanes for the urban public transportation, establishing a public transportation exclusive lane supply set, reallocating urban transportation OD quantity predicted according to urban transportation requirements based on the change of a road impedance function of urban roads after setting an initial public transportation exclusive lane; calculating to obtain the quantity of passengers transported by each road section in a road network in unit time and average trip time of passengers in the road section after reallocating the OD transportation quantity; establishing a connection road section set of a public transportation exclusive lane network, planning road sections in a set R into public transportation exclusive lanes, and communicating the public transportation exclusive lanes to form a network. The method provided by the invention considers the factor that starting and terminal points of the public transportation exclusive lanes can become bottleneck road sections, so that the capability of transporting the passengers by buses is improved, the attraction of the public transportation is increased and the urban traffic jam is relieved.
Description
technical field [0001] The invention belongs to the field of urban public transport, in particular to a method for planning and distributing a network of an urban bus lane. Background technique [0002] With the increase in the number of cars in our country, urban road traffic congestion is becoming more and more serious. Traffic congestion has brought a series of traffic problems, frequent road traffic accidents, and aggravated environmental pollution. Giving priority to the development of urban public transportation is an effective means to solve urban road traffic congestion. The priority of bus right of way fully embodies the concept of giving priority to the development of public transportation. The setting of bus lanes enables buses to enjoy the priority of road use. Therefore, bus lanes play a significant role in solving current traffic problems. Many large cities in my country have set up bus-only lanes. Practice has shown that setting up bus-only lanes can greatly ...
