Research on the Land Use Model in the Regional Traffic Demand Forecast

Abstract

The article analyzes the relationship between use of the cities in some areas and the traffic demand of each city in the region, pointing out the problems of the traditional use model in the regional traffic demand The problems include too much statistical work before the establishment of the model, the difficulty of the determination of the model's parameters because the models are non-linear, and as a result, the inaccurate relationship between the use situations and the factors, such as population, economic development, GDP, etc, about the traffic demand in the territory. The large amount of inaccurate statistics. skew the calculations. Because of the problems, one much briefer use model, which consists of only two steps, that is land use- traffic demand is established. The model connects use situations of each city in the area investigated with the traffic demand of the cities in the territory compared with the traditional use model being used in the regional traffic demand forecast, which takes three steps, that is land use - the factors about trip generations - traffic demand forecast. And so the two-step model can forecast the regional traffic demand briefly and accurately.
