Problems solved by technology
[0002] The operation and service of urban public transport is restricted by the carrying capacity of the platform, and buses and trams are also affected by the mixed traffic flow of urban roads, which leads to delays in the time dimension of vehicles and congestion in the space dimension, which intensifies the negative utility of passenger travel.
Earlier, most scholars took the full load rate of public transport vehicles as the core indicator for evaluating the quality of service (LOS) of annual public transport operations. Evaluation of operational services from a spatial perspective lacks comprehensiveness

[0038] The following is attached figure 1 The technical scheme of the present invention is further described.
[0039] Step 1: Collect the data required for the calculation of public transport corridor / network passenger flow congestion index, including public transport operation data and basic data, etc. The classification and acquisition methods are shown in Table 1;
[0040] Data required for the model in Table 1

[0043] The second step: parameter calibration, for the above Formulas (8) and (13) The parameter α in1 ,α 2 ,β 1 ,β 2 ,χ 1 ,χ 2 Make an estimate. The SP (Stated Preference) survey method can be used for parameter estimation, and the design dependent variable is T WTM and T RTM , and then set four independent characteristic variables—passenger flow density in the compartment (D C ), platform passenger density (D P ), interval travel time (T r ) and station waiting time (T w ). A questionnaire including different riding and wai...

The invention provides an urban public transportation passenger flow congestion index calculation method based on subjective perceptions of passengers, relating to the field of traffic engineering. The method is based on a 'limitation extension' thought, the subjective perceptions of the passengers on travel time and space congestion are systematacially quantized, are more close to physiological and psychological states of the passengers on a public transportation service and can be taken as one important index for measuring public transportation service level in future, quantizable public transportation operation and service performance dynamic index support are provided for an urban transportation industrial management unit and a public transportation monitoring command organization, anddecision support is provided for industry service monitoring, developing a bus operation service improving strategy and evaluating a public transportation investment effect.
Description
technical field [0001] The present invention relates to the quantitative characterization of passenger flow congestion in urban public transport (urban rail transit and ground bus and tram traffic), and proposes a quantitative characterization index for passenger flow congestion based on the idea of "time extension", which belongs to the field of transportation engineering. Background technique [0002] The operation and service of urban public transportation is restricted by the carrying capacity of the platform, and buses and trams are also affected by the mixed traffic flow of urban roads, which leads to the delay of vehicles in the time dimension and the congestion in the space dimension, which intensifies the negative utility of passenger travel. . Earlier, most scholars took the full load rate of public transport vehicles as the core indicator for evaluating the quality of service (LOS) of annual public transport operations. Evaluation of operational services from a...
