| Summary | This paper assumes that except for the tolled expressway, there still exists one alternative free road for all commuters that they can choose to reach their workplaces. Then we derive the optimal toll scheme under the electronic road pricing system (ERPS) at ramps of the expressway. The optimal toll for the expressway includes two parts of fare: First, a basic charge according to the length that each road user has driven along the expressway. Second, congestion tolls paid by the road user to ensure the efficient use of the expressway. The step congestion toll scheme are levied under the condition that the traffic flow is equal to the road capacity. This paper also evaluates the economic benefit from the ERPS at ramps of the expressway. The evaluation result is obtained by comparing the increased and decreased social costs that happened after implementing the optimum toll on the expressway. The result of the economic benefit will be objectively evaluated for the authority’s references. |
