Study on Toll Rate Model for Toll-by-weight Road Based on Cost Compensation

Aimed at lack of the pricing theory for toll-by-weight road and the measurement methods being irregular and non-uniform,the average annual maintenance costs of road were obtained using road maintenance cost model according to the road compensated costs combining with the toll road pricing theory and the investigated equivalent standard axles.Then taken the rate of toll-by-weigh as an unknown variable,the annual net cash flow was figured out based on the annual toll revenue,maintenance cost and other costs.The two rate models for toll-by-weight road,commercial road and government loan-repayment road,were finally established using the cost-inverse method.A couple of suggestions were put forward based on the key parameters of rate models for toll-by-weight road.Comparison and analysis show that the proposed model could provide reasonable and definite theoretical guidance for the rate calculation of toll-by-weigh road to result in proper development and effective deepening of toll-by-weigh work.
