• Abstract:
  Traffic and demand management are major strategies to control delay and congestion in highway bottlenecks including work zones. The Federal Highway Administration (FHWA) introduced innovative strategies, called Active Traffic and Demand Management (ATDM) to manage congestion. Speed harmonization, known as Variable Speed Limit (VSL), is one of the ATDM strategies. In the past studies on speed harmonization, the decision variables are advisory speeds displayed by changeable message signs (CMSs); however there is another feature which is the location of the CMSs that needs to be optimally designed. Thus the objective of this study is to develop and solve a mathematical program to find the optimal location of the CMSs and displayed advisory speeds.
