Abstract
A digital road network traffic state reckoning method includes: S1, acquiring traffic weight coefficients of vehicles; S2, calculating traffic weight coefficients of evaluation objects in the road network at different spatial scales; S3, reckoning traffic operation indexes of the different evaluation objects in the road network; S4, reckoning delay time indexes and average delay times of the different evaluation objects in the road network; S5, reckoning indexes of the numbers of times of stopping and average numbers of times of stopping of the different evaluation objects in the road network; and S6, reckoning indexes of mileages of congested roads and proportions of mileages of heavily congested roads of the different evaluation objects in the road network by using the mileages of the heavily congested roads and the traffic weight coefficients of the vehicles.
