Abstract

The maintenance and the rehabilitation of the urban road pavements are not often based on systematic program and scheduling but rather on emergency or on other not identified reasons. Moreover the Life Cycle Cost Analysis (LCCA), the only peculiar procedure for the management pavement, finds its own application for highway and motorway, even if it is possible to search the best investment for the urban interstate and arterials. By the light of the quantity of the involved resources, it seems necessary to define an operative methodology for programming the maintenance and rehabilitation activities for the urban pavement. The paper is oriented towards the development of a multidisciplinary approach to make decision on management of urban pavement using the basic concepts of the LCCA and micro-simulation model to define a scheme of work zone that minimizes the delay on the traffic flow. The best rehabilitation strategy should be characterized by the lowest users’ cost that depends on the time period of the work zone, which is conditioned by both own scheme and the provided treatment, and on “social cost” as increased travel time for queue generation . Different scenarios for different work zone plans were developed and a micro-simulation model was used to assess increased total travel time of a traffic flow within the maintenance area. In this work an analysis by means of the above mentioned approach was carried out on real scenario in the city of Palermo in order to point out the several frames of the adopted methodology.
