这反过来又取决于该地区的经济状况来进一步说明，可以假定线形图的横轴衡量每条车道每小时的车辆数量。纵轴表示旅行的需求或边际效益。选择在某条特定路线上行驶的驾驶员，其出行成本，即货币和时间成本的总和，即他们将三辆车的总和考虑在内。它们会继续驱动，直到两个轴都达到平衡。但在成本大于边际效用的情况下，选择不开车的人。通过对该图的分析发现，当失去平衡时，驾驶员选择不沿着特定的路线行驶。显然，为了社会的整体和谐与友好，社会中的交通拥堵需要得到缓解(Knox & McCarthy, 2012)。应用理论模型可以控制这种交通拥堵。这应该根据该地区的经济运动来调整。从规模经济的角度，把好地方的贸易从根本上分为五种类型。他们是哈姆雷特;如何在中心区位理论中对乡村、城镇、城市和区域首府进行广义的划分。交通规划需要建立在经济和货物贸易流动的基础上。
This in turn is dependent on the economics of the place to elucidate further, it is to be assumed that the horizontal axis of a line graph measures the number of vehicles per lane per hour. The vertical axis measures demand or marginal benefit of the travel. Driver who chooses to ride in a particular route factor in trip cost, the sum of the monetary and time cost i.e. they factor in the sum of the three vehicles. They will continue to drive until there is equilibrium reached in both the axes. But the driver who chooses not to drive in cases of the cost of driving is more than the marginal utility. From analysis of the graph it has been found that the drivers choose not to drive in a particular route when the equilibrium is lost. Evidently traffic congestion in the societies need to be alleviated for the overall harmony and amiability in the societies (Knox & McCarthy, 2012). Applying theoretical models can control this traffic congestion. This should be manoeuvred according to the economic movement of the place. Based on the economics of scale of the trade of good places are classified into fundamentally five types. They are hamlet; village, town, city and regional capital how the places are broadly classified in central place theory. Traffic planning needs to be developed based on the economics and the flow of trade of goods.
In these situation viable alternatives such as construction of highways, usage of tolls is suggested (Knox & McCarthy, 2012). Roads need to be restructured to allow smoother traffic flow. In the case of toll the initial cost of transaction might be higher. Nevertheless based on marginal utility principle it can be found that the toll compensates by reducing time of cost and also reduces externalities in this process. Flow of the trade of goods determines the flow of traffic in the cities. Traffic congestion causes a number of adverse effects to the society. They increase the externality factor. This can be detrimental to the trade and supply chain operations of a place. Hence there is an imperative need to address this traffic congestion of a place. From analysis it has been found that three variables determine the route a driver chooses to take. Distance, costs of the time spent and monetary travel cost are the three important variables that driver factor in while taking a particular road. Using marginal utility principle the actual cost of travel must be equal to the social cost obtained from the travel.
