【摘要】 城市道路的发展状况已经成为制约城市社会经济发展的“瓶颈”,许多地区采取了各种各样的措施来缓解交通压力,但是收效甚微,关键在于我们没有从根本上认识产生这一现象的根源。本文通过建立城市道路与人口的非线性动力学模式,分析城市道路与人口之间的关系。更多还原

【Abstract】 With the development of the economy and the increase of the population in the cities, traffic jam has become a serious problem. It brings a threat to the harmonious development of urban economy and society. How to solve or allevia te the "bottleneck" of the traffic jam in the cities has become an important dis cussion issue confronted by all the levels of the governments in China. Many cou nter-measures have been taken as possible as we could. Utilizing the nonlinear theory, this paper attempts to make a research on the dynamic relationship between the acreage change of the roads and the populat ion in the cities, and forecasts their developing trends. Through setting up the nonlinear dynamic model of the roads and the population in the cities, the pape r also analyzes their essential relationship. The results show that the stable p opulation in the cities is positive to the stable road acreage occupied by the f low passengers; the increase of road acreage is constrained by the maximum road acreage; the amount of road has a proportion to the maximum amount of population and inverses to the road flow capacity. The utility rate of the resources will be improved and the communication system will be managed well so as to increase the flow of goods and passengers. From the research, we can see that it is vital for us to balance the population and the economic development.更多还原
