Preferential access to the and transportation alternatives in the corridor. Managed Lanes will allow buses to provide high-speed, "rapid" service. Bus Rapid Transit Centers (BRTCs) are planned adjacent to the freeway in Mira Mesa, Sabre PURPOSE AND NEED Springs/Rancho Penasquitos, Rancho Bernardo, near I-15 has serious traffic congestion problems affecting North County Fair and in Escondido. commuters, businesses, and regional goods movers. The Average Daily Traffic (ADT) on the corridor today In addition, the stations will have "Park & Ride" lots for ranges from 170,000 to 290,000 vehicles, with daily carpools and will be connected to the managed lanes by commute delays ranging from 30-45 minutes. In direct-access ramps, allowing buses and HOVs to quickly addition, I-15 is subject to additional delays during rainy bypass freeway on-ramps. The BRT System provides days, incidents, or special events due to a lack of needed transportation alternatives to single occupancy adjacent parallel routes. vehicles and reduces demand and congestion on the corridor. Traffic delays will increase as the regional economy and populations expand along the corridor. By 2020, SANDAG is conducting studies of transit needs between average volumes are expected to approach 380,000 SR-163 and Interstate 5.

Managed Lane traffic may be configured using a movable barrier to accommodate the specific traffic demands throughout the day. Caltrans and SANDAG employ highly skilled professionals familiar with design sequencing For example, the movable barrier -- which is similar to projects.
