TRAFFIC FLOW PREDICTION SYSTEM USING SPATIOTEMPORAL STOCHASTIC MODEL

摘要

The present invention relates to a kind of magnitude of traffic flow evaluation systems to use space-time probability system. Traffic flow evaluation system can probability Geostatistical analysis in real time and historical traffic data, using the speed and vehicle number image data and input and from VDS sensors and accurately calculate Business Stream according to the Business Stream of geographical relationship. Therefore, the present invention includes: offline estimation device, generates a model to indicate the Business Stream in relational spacetime domain; With On-line Estimation device, a typical value is generated, installed on the road measured by the various sensors of statistical analysis of the single time point by data and using estimation model, model is estimated by off-line learning, to export the traffic in some period. ;The 2015 of copyright KIPO submissions
