Creating quiet city zones by noise charges and quiet vehicles. Part one: Traffic flow calculations

摘要

One important subject in the EU directive 2002/49/EC regarding noise maps and action plans is to establish or preserve quiet areas. In a study within the EU FP6 project "Quiet City Transport" we have analyzed the possibility of creating Quiet City Zones. The concept is to utilize quiet vehicles and apply restrictions on noisy vehicles by means of closed gates or noise charges to reduce traffic flows and noise source emission in a zone. Traffic models were used to forecast the effects on traffic flow, using a prediction system modeling the travel demand and transport system of the entire Stockholm County. Traffic flow data from each simulation were used as input to create related noise maps of a selected study area. Applied methods and results are presented in two consecutive papers. In this paper, part one, we present traffic flow calculations. In addition, using a car type choice model we analyze what impact noise charges have on the share of low noise vehicles in the car stock. In part two, noise calculations and noise effects are presented.
