By using the bus GPS data and map matching algorithm, this paper depicts the actual bus running status, counts the one-way time consumption and arrival time interval of the bus, quantitatively analyzes the reliability of bus travel time, evaluates the running effect of bus lines, and puts forward a method of identifying road sections with high traffic congestion based on an increasing rate of travel time. With the bus track data in Harbin as an example, this paper analyzes the operation of a bus No. 84. The results show that the one-way punctuality of this line is 88. 33%, and the one-way punctuality stability is 61.55%. The congestion model based on an increasing rate of travel time can effectively identify frequently congested sections of the line, and spatial distribution of the congested sections can be seen on the heat map. Through the analysis of the track data, changing characteristics of the bus operation are discovered, which provides an important reference for solving urban traffic congestion and improving bus service level and reliability.

In order to optimize the in - road parking layout and improve the utilization rate of parking facilities in the city, so as to improve the city * s static traffic situation and solve the traffic congestion problem, this paper first conducts a data survey on the parking situation in the commercial district of Le Song in Harbin, and obtains the basic data such as the supply of parking spaces on the road, the number of parking during rush hours and the parking characteristic parameters. After finishing, the parking characteristics and sat¬isfaction degree of parking status are analyzed, and the factors that affect the demand and supply of parking spaces are obtained. Then, an in - road parking demand model based on the regional road network capacity, the comprehensive reduction factor of road network us¬age and the proportion of parking behaviors is established. The demand for in - road parking spaces in Harbin * s Le Song commercial district is predicted and corrected. The number of available parking spaces for two different parking modes, oblique parking and vertical parking, is calculated. The analysis results show that it is more reasonable to set up parking spaces at an angle of 60 degrees. At last, it puts forward various schemes to adjust the parking price system on the road, feasible suggestions to improve parking utilization rate and management methods. The research results provide a reliable theoretical basis for the formulation of on - road parking planning schemes and management strategies [ABSTRACT FROM AUTHOR]
