Continued growth in travel on congested freeway corridors exceeds agencies abilities to provide sufficient solutions and alternatives based on traditional roadway expansion and improvement projects. High construction costs, constrained right-of-way, statutory restrictions, and environmental factors are pushing agencies to explore solutions such as active traffic management and managed lanes, which improve safety by reducing collisions and nonrecurring congestion and maximize throughput under congested conditions. Finding cost-effective options to mitigate recurrent and nonrecurrent congestion on freeway facilities is one of the most significant challenges State and regional transportation organizations face. |
