Abstract

A method for obtaining OD real-time running time between adjacent checkpoints comprises the following steps that (1) parameters are set and initialized; (2) a real-time vehicle passing information table is established, vehicle passing information of all checkpoints is inserted in the table, and the vehicle passing information at least comprises the following keywords such as vehicle types, plate numbers, vehicle passing time, checkpoint ID and checkpoint position information; (3) the statistical process is conducted for the ith time; (4) according to a calculation result obtained in the step (3) and the following mode, OD real-time running time Xi counted at the ith time is adjusted and the length of a statistical time window at the i+1th time is determined; (5) after T minutes, the statistical process of the next period is conducted. According to the method for obtaining OD real-time running time between the adjacent checkpoints, accuracy is good and instantaneity is good.

Description

technical field

[0001] The invention relates to the field of OD travel analysis, in particular to a method for acquiring real-time OD travel time between adjacent bayonets. Background technique

[0002] With the continuous development of urbanization in my country, the population and the number of motor vehicles in large and medium-sized cities have grown rapidly. However, due to factors such as geography, space, capital investment, and road construction cycle, the speed of urban road construction is relatively slow, and urban roads are basically saturated. state, road congestion is widespread. Therefore, how to choose travel routes and avoid peak road sections has become an important topic in the analysis of citizens' travel.

[0003] The existing OD travel time algorithm generally divides the long path into several small road sections, counts the travel time of each road segment by segment, and finally sums up the OD travel time.

[0004] With the improvement of the bayon...
