Statistical Data Enabled Navigation System Experiment in Beijing

The paper introduces the research on statistical and live traffic information aggregated navigation experiment in Beijing. Around 7000 taxies running on roads send GPS data to the traffic information center to produce live traffic data, and the center accumulates the probe data for months. By analyzing historical probe data, statistical database is generated, and in-vehicle navigation system can search route based on live traffic data downloaded through CDMA network and the statistical database produced offline. The field test is carried out in January 2007 in Beijing.
