THE COMPARISON BETWEEN PREDICTION AND MESUREMENT OF THE TRAFFIC INVESTIGATION FOR THE ENVIRONMENTAL IMPACT ASSESSMENT OF THE URBAN SCIENCE PARK.

We report the outline of the traffic investigation for the environmental impact assessment of the Science Park that located in urban area. In 1985, we predicted and evaluated the traffic volumes at 22 links around the developping area before construction of the Science Park. In 1990, we measured the traffic volumes at the same links after completion of the Science Park. We compared the mesured value with the predicted value. The predictive average error ratio is 9.4 per-cent except several links around the new opened supermarket whitch we could not consider in our prediction.
