State Route 14 Reversible Lanes High Occupancy Vehicle Feasibility Study and Preliminary Engineering, Los Angeles County, California
KOA conducted a study and preliminary engineering for the Los Angeles County Metropolitan Transportation Authority to examine the potential of constructing reversible High Occupancy Vehicle (HOV) lanes on the State Route 14 corridor between Interstate 5 and the Kern County line. The project sought to maximize the capacity of the SR-14 while minimizing the need for additional right-of-way and associated construction costs. This project studied the feasibility, costs and available funding mechanisms for two alternatives between I-5 and Avenue P: (1) conversion of the existing HOV lane pairs into an AM / PM reversible operation, (2) construction of a third HOV lane to ultimately convert to a 3-reversible HOV lane operation. The study addressed issues identified by Caltrans, including the safety and efficiency of the reversible HOV lane operation with transit and mix-flow traffic, and examined accessibility to and from the reversible HOV lanes along the entire SR-14 corridor.
