Overview of Original ObjectivesOverview of Original Objectives
Increase operating speed and time point adherence using bus signal priority and queue jump lanes
Provide dynamic bus arrival and system bulletins on-board and at stops
Improve overall passenger comfort with enhanced stations and low floor, low emission vehicles
Operating TargetsOperating Targets
• Station spacing ± every mile• Schedule time at ± 85% general traffic speed• Tight time point adherence• Minimized dwell time at stops• Headway no less than every 10 minutes
peak, 20 minutes off-peak• Conventional service retained at reduced
level

StatusStatus
• Queue jump lanes at Page Mill and Arastradero completed
• AVL/AVI and articulated coaches in service• Beta test completed on bus priority software• Signal hardware upgrade procurement
Phases I & II in process• Preliminary station sites identified
Bus Signal PriorityBus Signal Priority
Caltrans has developed signal controller software modifications to provide bus priority functionality
Articulated coaches are equipped with priority request transponders
Funding provided for bus signal priority along El Camino Real from Race Street to the Palo Alto TC by BAAQMD (70% of the corridor)
Bus Priority Operating PrinciplesBus Priority Operating Principles
Pedestrian calls as well as railroad and public safety preemption protected
Maximum frequency of priority grant every second signal cycle
No priority during transition to coordination
Phase skipping not permitted
Priority RequestsPriority Requests
No manual intervention by driver Only late buses place requests Priority requests granted on a first-
come first-served basis Priority granted as early green and/or
extended green Truncation on check out or time out
ScheduleSchedule
Procurement of hardware in process Phase I implementation in Spring ’04 Phase II implementation in Summer
‘04 Before/after study conducted
longitudinally by Cal-Berkeley PATH on both phases
