- Abstract:
- Aiming at the problem that the existing road network data model cannot make effective modeling and expression of dynamic network topology for different types and different time periods, and the traditional path planning method lacked the support of time-dependent traffic restriction information, which cannot meet the basic daily traffic demands, the dynamic network topology of time interval, vehicle type (number of mantissa) and restriction information in the time-dependent traffic restriction was analyzed. The dynamic road network topology model under different time-dependent traffic restrictions was proposed so as to achieve the dynamic modeling of the complex city traffic network connectivity topology for different vehicle types (number of mantissa) and different time intervals. Meanwhile, based on the Dijkstra algorithm, and combined with characteristics of network model of time-dependent traffic restriction road and other algorithms, such as judgment of nodes connectivity and improvement of judgment of vehicle type, time, steering limit, a route planning optimization method was constructed on the basis of time-dependent traffic restriction information. Taken the time-dependent traffic restriction information of Wuhan City road network, Wuhan Yangtze River Bridge and Wuhan Yangtze River Second Bridge as test data, the traffic restriction route planning experiment of different vehicle types and different periods was carried out to verify the feasibility of this model. The results show that the dynamic road network topology model and route optimization method on the basis of time-dependent traffic restriction perfect the deficiencies of the current traffic data model and route planning method, and also satisfy the daily travel demands under the new road network data.
