Dynamic route guidance method oriented to urban traffic

Abstract

The invention discloses a dynamic route guidance method oriented to urban traffic, relating to various optimal route planning methods in a geographic information system (GIS) and an intelligent traffic system. The method comprises the following steps: through taking a GIS (geographic information system) software product ArcGIS road model provided by the Environmental System Research Institute (ESRI) in America as the basis, loading a road traffic map of the Beijing city, simulating the operation efficiency of twelve route planning methods such as a PSP (play station portable), Dijkstra and soon in different road traffic conditions, and displaying the dynamic traffic information of major roads in real time to realize the presentation of the dynamic traffic flow information; and simulatingthe operation efficiency of different route planning methods in dynamic traffic condition by successfully applying the dynamic traffic flow information in the computation of the dynamic optimal route. The prototype system belongs to the field of transportation, and can be applied to the simulation experiment of the optimal route planning method in an intelligent transportation system, a vehicle navigation system and the GIS, thereby providing a reference and basis for the research on road guidance systems.

AI Technical Summary

Benefits of technology

The technology described by this patented describes various ways that optimize paths within a computerized or smart vehicle (S/AV). These techniques help predict how fast moving vehicles are going through certain areas during their journey without being stopped due to obstacles like buildings or other structures around them. They also allow users to plan routes based upon these predictions. Overall, they aim to improve efficient driving systems while reducing costs associated therewith.

Problems solved by technology

This patented describes an invention that helps guide vehicles safely along roads by collecting relevant information like road conditions or accident scenes on their way during travel. It uses different techniques including routing algorithms based upon geographic coordinates (GPS) technology, radar detection systems, GIS databases, etc., which help determine where they're located accurately while navigating around obstacles.
