14 Purpose and Need This freeway experiences high travel demand, especially during peak commute periods. This has created severe traffic congestion and impaired mobility along the route. At various locations, travel demand has exceeded highway design capacity, resulting in bottlenecks. These bottlenecks have been created by multiple factors, including high traffic volumes, short weaving and merging areas, lane drops, limited sight distances, inadequate intelligent transportation system (ITS) elements, and incomplete bus/carpool and auxiliary lane networks. Heavy congestion and stop-and-go traffic have contributed to increased vehicle emissions, increased travel costs, and reduced travel time reliability.

25 Managed Lanes Value Priced Lanes Toll Lanes HOT Lanes HOV Lanes Truck Lane Restrictions Use of HOV Lanes by other Vehicle Groups Multi-faceted Managed Lane Facilities Value Priced Lanes Toll Lanes Bus ways Transit ways Exclusive truck facilities Pricing Traditional toll lanes and toll lanes that use congestion pricing, where price is varied during certain time periods in order to manage demand (e.g., peak-period surcharge or off-peak discount). Vehicle eligibility The lanes are managed by allowing certain vehicles or restricting others; minimum occupancy is an example of an eligibility restriction. Access control An example would be express lanes where all vehicles are allowed but access is limited during long stretches of the facility, minimizing turbulence in the flow of vehicles.
