ABSTRACT

The performance of maintenance actions are needed in order to overcome road networks degradation. Such actions modify the traffic and road environment conditions offered to users on a specific part of the network, even if on a temporary basis, creating the so call “work zones”. With the purpose to support strategies and practices to minimize the impacts of work zones, this study addresses the assessment of impacts through methodologies such as the one proposed by the TRB in HCM2010 for the calculation of capacity in sections under construction; the binary logistic regression applied to official crash data to identify the main contributing factors; and previous work developed by the authors on the modeling of road user costs. The study takes into account the Portuguese reality and is supported by other experiences, given in the end the framework to deal with the impact of these zones.
