Congestion on the freeway is more
frequent due to several traffic incidents, namely traffic accidents, debris on
the road, vehicle breakdown, and collision with guardrails than any other
incidents. These, in turn, affect the operational performance of the freeway by
increasing queue length, volume, and density. Consequently, effective freeway
management strategies can help to minimize these impacts. The study
investigates and summarizes existing studies to identify the reasons for and
effects of the traffic incidents. Attention is given to the available solutions
of the freeway traffic incidents management. The ultimate goal of this study is
to identify the gaps which are not yet addressed to improve the operational
effectiveness of the freeway. This study was conducted through a comprehensive
literature review of existing refereed publications, established standards, and
formal guidelines. Literature was sought through the Transport Research
International Documentation (TRID) database, IEEE Transactions database, and
google scholar search engine. Research focusing on freeway traffic incidents is
a growing concern in transportation operations, as transportation network
performance depends on it. Due to the advancement of technology, emerging
vehicle technologies like connected vehicles have the potential to address
these problems affecting the US transportation system and revolutionize
mobility in the future. The study can serve as a reference for the researchers
that are involved in freeway traffic operations.
