The article proposes that traffic-induced emissions pose a serious threat to air quality in many metropolises. The paper stresses that the urban transport planning must be conducted under the constraint of environment. As the traffic flow on the urban roads usually is the mixed traffic flow, there is a need to analyze the mixed traffic volume to implement unified standard of the vehicles. That is, the different kinds of vehicle can be converted to the Passenger Car Equivalents (PCE). Many researches put forward the PCE based on the road traffic capacity. In this paper, the conception of vehicle equivalent conversion coefficients based on the emission is presented. The PCE based on the emission is calculated according to the emission concentration variation when some kind of vehicle is added into the traffic flow. Finally, the PCE based on the emission is recommended taking the field measurement data from Yangpu District of Shanghai as the case.
