Police Vehicle Navigation System Design And Implementation

Police vehicle navigation system can be real-time traffic information and location information available to the police,so that police officers in the day-to-day activities to maximize their understanding of the situation and can docking alarm at the location or locations and the optimal path planniug the best route guidance,so that (?)olice can be reached in the shortest possible time,purpose and will effectively improving the efficiency and response alarm detection probability.Real-time monitoring center can monitor police position,a scientific and timely distribution of the police to provide support results.Police also can be adopted at the scene information wirelessly transmitted back to the command center for the leadership provide a basis for scientific decision-making.At the same time,civilian police through wireless means landing public security information network,eight real-time information resources for inquiries.In this paper,Police Vehicle Navigation System positioning technology,dynamic path planning,navigation digital map data and dynamic maintenance and update traffic information collection,processing and publication and the forecast road traffic conditions and other related technologies.Second on the police vehicle navigation system with hardware and software design,the final detailed vehicle navigation system for police use of vehicle location module,objectives retrieval module,line guide the planning module and line modules.
