Abstract:
An environmental traffic impedance model is constructed based on generalized impedance. First,a method of calculating pollutant concentration on the bottom of street is given. Then vertical distribution of pollutant concentration is obtained through unitary nonlinear fitting. Healthy effect caused by atmosphere pollutant is quantitatively analyzed by using concentration-response relationship between pollutant concentration and healthy effect, and then this healthy effect is monetized by willing payment method. Generalized impedance model considering health impacts is constructed, which is based on traditional BPR(bureau of public road)function. At last, an example of generalized impedance model based on CO is constructed and its characteristic is analyzed. Health impacts monetization is the most important part in the generalized impedance model which is based on health impacts. Impedance calculated by BPR model is a fixed value when the traffic volume is fixed. However, generalized impedance is variable if vehicle type proportion changes, because different vehicle types have different emission factors.
