Absctract	Nowadays, Transportation system provides a necessary linkage between people and the society, which is one of the most demanded services and it shapes people’s daily living by bringing convenience. Therefore, people are considering in taking account of user cost while traveling. As the pavement condition directly affects the user cost and comfortability of drivers, pavement rehabilitation and maintenance are unavoidable in order to preserve serviceability of the roadway. Occupancy of travel lanes during rehabilitation is an ordinary situation, but it imposes extra cost on the users due to traffic disturbances. As a result, it is necessary to minimize the cost owing to rehabilitation activities. Optimization problem regarding the agency cost due to pavement maintenance and rehabilitation activities has been widely addressed by a numerous researcher and included in the pavement management system (PMS). Although there are also many researching articles inclusive of similar optimization problems regarding the user cost due to roadway closure, their solutions are limited by either network properties underestimation or inefficient computation even if network topology is being considered. In fact, there is research showed the user cost is much higher than that of agency cost, it is crucial to quantify the traffic disturbances efficiently and include it into PMS. Therefore, optimization problem in minimizing user cost, which inclusive of additional user travel cost owing to resurfacing and additional operational cost experienced by users because of the low fuel efficiency resulting from high pavement roughness, within a network-level pavement system due to complete or partial roadway resurfacing is proposed to be dealt in this research. This report performs a preliminary simple case on studying user cost optimization problem while considering both transportation network topology and traffic redistribution. The computation result satisfies the Pareto Optimality and it shows the Pareto set which could help to make focused tradeoffs within the related parameters. This report consists of five chapters, including introduction and objective, background, methodologies, a case study showing solution procedures and results, and conclusion. References and Appendix for detail steps in solving the optimization problem and results would also be provided at the end of this report.
