Development of the system for estimating the reduction of road traffic pollution by traffic managemental countermeasures

The purpose of this study is to develop the system for estimating the reduction of road traffic noise and air pollution in addition to the measures on traffic safety and smoothness by traffic manageinental countermeasures. The system developed here consists of three core simulation models and the expert system mentioned as follows, 1). Traffic Flow Simulation Model; It is micro simulation model which is based on MICSTRANII. 2). Noise Prediction Simulation Model; It predicts the noise levels at any roadside point in simulation networks, by using the output of 1). 3). Emission Prediction Simulation Model; It predicts the air pollution levels on any road link in simulation networks by using the output of 1). 4). Expert System; It includes the database which are input and output data on simulation models and various countermeasures. By using this system, the effects of individual countermeasure or the effects of the combined countermeasures considered to be implemented, are automatically obtained through the simulation experiments under the given conditions or through referring to the database.
