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 methodolog
