The invention discloses a road operation analysis system, and relates to the technical field of traffic planning and traffic management. The system comprises a road condition analysis module used foracquiring and storing road condition information in real time, a congestion identification module used for determining a frequently-occurring congestion road section, a congestion mileage and a congestion proportion based on massive road condition information, a traffic flow source tracing module used for tracing a vehicle source and a destination of a selected road based on historical trajectorydata, a road flow analysis module used for analyzing and determining flow data in a road area based on massive floating vehicle GPS data, etc. According to the system, comprehensive analysis of road operation characteristics is realized through the road condition data, the floating vehicle GPS data, traffic flow source tracing analysis data and the like, and formulation of traffic planning and traffic management schemes is supported.
Description
technical field [0001] The invention relates to the technical fields of traffic planning and traffic management, in particular to a road operation analysis system. Background technique [0002] After the completion of the highway, with the continuous increase of traffic flow, traffic jams often occur, and there is a hidden danger of causing a series of traffic accidents. With the explosive growth of the number of vehicles in recent years, traffic congestion has brought enormous pressure to road managers. [0003] At present, there is a single method for detecting road congestion events at home and abroad, and the early warning is weak. The single method often has problems that cannot be detected in special cases, resulting in untimely early warning. Contents of the invention [0004] The purpose of the present invention is to provide a road operation analysis system, which can analyze road operation characteristics from various aspects, support the formulation of traffic ...
