User costs related to maintenance operations represent a considerable amount of public expense in the United States. They are in the forms of extra fuel consumption, higher vehicular operating and maintenance costs, and additional travel time. As the demand for road maintenance keeps increasing, there is a tremendous need to reduce the user costs by introducing new technologies. Automating road...

Rapid growth in a number of vehicles on roadways accelerates pavement deterioration trends. Pavement inefficiency in carrying the applied load from passing vehicles results in spending significant costs on continues Maintenance and Rehabilitation (M&R) treatments. Lane closure owing to the implementation of M&R operations incurs enormous costs on road users. The research aimed to calculate, and...

In this paper a methodology for the development of multiple impact models for road networks is described. Road impacts can be categorized into impacts for different stakeholder groups, namely the public, the owner and the road users. The current investigations address multiple impacts only for road users, but the developed methodology can be extended to estimate the impacts of all stakeholder g...

This paper identifies a set of important criteria to consider when evaluating potential road user charging (RUC) systems, grouped into charging accuracy, system costs and societal benefits, flexibility and modifiability, operational aspects, and security and privacy. These criteria are then used in a comparative analysis of four RUC candidate systems for heavy goods vehicles in Sweden. We concl...

R oad user cost is an important consideration in highway economic analyses. The two main components of this cost are (a) motorvehicle running cost and (b) travel time. Highway engineers and economists know that, for road user costs (running costs plus travel time), lower traffic volume usually provides the least unit cost; as volume increases, the cost to the user increases because of congestio...
