Abstract
In this paper, a method is proposed to build a real-time massive vehicle big data collection platform, and develops BD GNSS sub-meter navigation and 4G communication systems for private cars. Through the analysis of real-time sparse distributed urban transportation network data, the road space-time congestion levels are graded and Chromaticity graph are modeled. A new type of urban traffic cars incentive mechanism is proposed to retrieve and process the private car traffic rule and statistic. The case studies were carried out in typical areas of Jinan City, including the information platform prototype design, time-space road jamming rule design and model construction, BD high-precision sub-meter road test and data comparison analysis.
