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.
