【摘要】：城市主干道投资时机对于促进城市经济发展,提高投资资金的使用价值具有重要的意义。目前,我国在城市主干道项目的决策中往往注重效益的大小,而忽视了对最佳投资时机的选择。本文首先建立道路通行时间模型来研究城市主干道上通行时间与交通量的关系,从汽车通过城市主干道的时间与交通量的关系着手,再通过建立城市主干道交通量预测模型,基于城市智慧交通综合管控系统来估计城市主干道上未来的交通量,从而确定未来城市主干道上的交通密度,交通密度等于或者刚超过最佳密度的时间就是城市主干道的最佳投资时机。最后,以某市琴台大道罗七路为例,对城市主干道投资时机进行实证研究,以期为城市主干道工程正确地进行项目决策,适宜地选择最佳投资时机提供参考。
[Abstract]:The timing of urban main road investment is of great significance for promoting the development of urban economy and improving the use value of investment funds. At present, our country often pays attention to the benefit in the decision of the urban main road project, but neglects the choice of the best investment opportunity. This paper first establishes the road traffic time model to study the relationship between the traffic time and the traffic volume on the urban main road, starting with the relationship between the time of passing through the city main road and the traffic volume, and then establishing the traffic volume prediction model of the city main road. Based on the urban intelligent traffic management and control system to estimate the future traffic volume on the urban main roads, and thus determine the traffic density on the future urban main roads, A time when the density of traffic is equal to or just exceeds the optimum density is the best time to invest in urban main roads. Finally, taking the seven roads of Qintai Dadao in a certain city as an example, this paper makes an empirical study on the investment opportunity of the urban main road, in order to provide a reference for the project decision and the optimal investment opportunity for the urban trunk road project.
