Abstract: Since the road system can not meet the traffic demand generated by the daytime population, traffic congestion has restricted urban economic and social development. Based on nonlinear dynamics theory, this paper analyzes the relationship between the area of urban road and the daytime population. The result shows the number of urban daytime population is proportional to the area of urban road at steady state. The author also found that the increase of urban road area is constrained by the maximum road area of a particular area at the city. When the road area is fixed, the number of urban daytime population is inversely proportional to the travel intensity.Abstract: Since the road system can not meet the traffic demand generated by the daytime population, traffic congestion has restricted urban economic and social development.
