Improving the Safety of Mobile Lane ClosuresAbstract:
This digest contains excerpts from a study conducted for National Cooperative Highway Research Program (NCHRP) Project 20-05, Synthesis of Information Related to Highway Problems. The objective of this report is to synthesize practices employed by transportation agencies during mobile lane closures and to summarize research carried out on different components of mobile lane closure. There are two components to this report. The first is a literature review that includes an overview of the terms applicable to mobile lane closures and their definitions, as used by different agencies; an overview of existing guidelines, handbooks, and manuals; current experiences and notable practices
employed by various agencies; and an overview of existing research that evaluates the effectiveness of different practices and
technologies. The second component is a survey questionnaire that addresses the state of the practices employed by (U.S.) state and (Canadian) provincial transportation agencies.
