Basic Methods of Peak-Hour Traffic Generation Forecast about Urban Commercial Complex

Based on analysis of the traffic impacts characteristics of the urban commercial complex, the article proposed that single-functional project itself generated traffic volume is related to time, and conforms to the corresponding Poisson distribution function. However, the multiple-functional complex itself generated peak-hour traffic volume is not a simple sum of each single-function peak volume, but is calculated by superposing the each function respective traffic density functions. Meanwhile, the article also explored the superposition and calculation method to obtain peak-hour traffic volume during forecasting the trip generation of the urban commercial complex.
