Evaluation of work zone strategies and user delay costs associated strategies and treatments.

The transportation sector is an integral part of the local, provincial and national economies. There are three important issues, including mobility, safety and economics, which must be considered when highway work zones are engineered. These competing issues are important to the key parties involved in highway construction, which include the owner, the transportation agency, hired contractor, consultants and the traveling public. To effectively assess these issues, this research is divided into four Modules. Module One focuses on developing work zone strategies appropriate for the construction being performed. Module Two investigates methods of improving safety within work zones. Module Three develops a prediction model for user delay cost while Module Four is a multi-variant decision model to assist transport agencies in incorporating an appropriate amount of user delay cost for a given facility type. The paper provides recommended practices and prediction models to improve mobility, safety and balance the economic impacts between key parties.
