Research On Dynamic Equilibrium Model Of Public Transportation In Peak Period Based On Seat Availability Reliability

Transportation is the blood of the city.It is extended by the development of the times and continues to sublimate with the progress of science and technology.However,the vigorous development of traffic demand has led to frequent traffic jams during peak hours,which has a major impact on the regularity and reliability of public transportation system services,and has caused great inconvenience to travelers.In order to provide reliable public transportation services,it is very important for bus operators to weigh the relationship between operating costs and service levels,and how to provide reliable bus operation services with limited resources and capacity allocation.This article first defines the concept of available seat reliability from the perspective of improving passenger travel comfort,builds an analytical model to study the factors that affect the reliability of available seats,and combines real passenger travel data to prove that reasonable setting of departure intervals can effectively improve station seating Reliability,and further obtain the available seat position interval of each station,and evaluate the influence of different departure intervals on the seat reliability.Taking into account the interests of public transport companies,increasing the frequency of departures to ensure higher seat reliability costs is not conducive to achieving its target profit,and changing bus models is an easily accepted solution for public transport companies.This paper then establishes a dynamic single-point and single-point dynamic equilibrium riding model based on the reliability of seats,and researches on the travel behavior of passengers during peak hours,analyzes the nature of passenger travel in an equilibrium state,and Through two examples,comprehensive and intuitive analysis of passenger travel characteristics and laws.The results show that changing the car model is also a scheme that can improve travel comfort.There are certain rules for passenger travel under capacity constraints.The bus company can study the behavior of travelers in depth and improve the operation plan accordingly to improve the level of bus service.It has certain reference value.This paper considers from multiple perspectives of bus passengers and bus companies,and strives to provide reliable bus operation services under the premise of limited resources and capacity allocation.It has important practical significance to alleviate the problem of public transport congestion from the system level.
