ABSTRACT
Traffic environment deterioration under adverse weather condition is important cause to induce traffic accident. In order to ensure traffic safety, a method to identify safety state of traffic environment must be found and the safety state should be sent to road users for reminding and guiding them in time. That is also one important content among intelligent transportation systems(ITS). This paper introduced two means to collect information about traffic environment under adverse weather condition, which were roadside sensors technology and floating car technology. The information included tire-road friction, atmosphere temperature, humidity, pressure, wind speed and direction, visibility. Then the structure and principle of these two technical equipment were analyzed. Lastly, a good method called D-S evidence inference based on multisensor information fusion theory was put forward to process those collected information.
