Running conditions closely related to the running safety of vehicles in forest areas and factors affecting using performance are analyzed and a battery of measures are put forward to ensure running safety in forest areas.

Using a set of measuring system installed on a testing vehicle, 15 criterion numbers, which describe the details of vehicle′s driving pattern and emission characteristic on real road condition of Tianjin, are obtained from a large quantity of raw data.

This paper investigated the driving patterns and the traffic conditions on three kinds of roads,which were highway,arterial road and residential road,in the urban area of Shanghai.
