• Abstract:
  Traffic congestion is an increasing problem in the nation’s urban areas, leading to personal inconvenience, ; increased pollution, hampered economic productivity, and reduced quality of life. While traffic congestion tends ; to continuously increase, growth in transportation infrastructure is limited by financial and land availability ; constraints. This has placed an increasing emphasis on using dynamic traffic management strategies, such as ; speed harmonization and peak-period shoulder use, to efficiently manage congestion using existing freeway ; capacity. This project implemented various strategies of variable speed limits and shoulder use and assessed their ; impact on traffic operations and safety of freeway. These strategies were found to homogenize traffic and create ; safer driving conditions, but did not increase the throughput of the system. The ITS devices required to ; implement these strategies, enforcement issues, potential impediments in their implementations, and a framework ; for cost-benefit analysis to determine the economic viability are also discussed.
