vta background
VTA Background
  • VTA recently celebrated its 20-year anniversary for introduction of light rail in San Jose
  • VTA operates 42 total miles of light rail in several cities
  • The VTA system includes 62 light rail stations and 21 park & ride lots
  • The current VTA system is the product of a series of light rail extensions

VTA Safety Review Board

  • Rail System Safety Review Board (RSSRB)
    • Reviews and approves safety issues
    • related to light rail
    • Includes VTA staff members from all departments
    • CPUC staff participates in RSSRB meetings
    • Responsible to monitor safety of the system
    • Identifies opportunities to enhance safety
slide15

Focus Areas

  • VTA has been evaluating intersections based on number and type of incidents.
  • Two main areas of focus to enhance system safety:
    • Left turn incident
    • Track intrusion
slide16

Examples

Left turn incident

slide17

Examples

Track intrusion

slide18

Analysis

  • Conducted Analysis
  • Formed work group
  • Obtained incident reports and records
  • Reviewed witness statements
  • Visited incident locations
  • Developed Findings
  • Identified primary cause of incidents
  • Searched for common links between incidents
  • Proposed recommendations
slide19

Findings

  • Left Turn Incidents
  • Incidents mainly from drivers from local area
  • However, caused from drivers lack of attention
  • Track Intrusion
  • Driver not distinguish track from roadway
  • Track flush with road
  • Drivers did not notice low track curb
slide20

Recommendations

  • Left Turn Incidents
  • Relocation of limit lines
  • Install signage “ Stop Here on Red”
  • Enhance pavement marking
  • Public education and operators training
  • Track Intrusion
  • Install bollards (markers) with reflective striping and markers
  • Install bright reflective signage
  • Public education and operators training
slide21

Mitigation Examples

  • Karina Court/First Street
  • Relocate limit lines
  • Install pavement marking
  • Replace active train approaching sign with two flashing messages.
  • Install signage and modify traffic loops
slide22

Mitigation Examples

  • First Street/Tasman Drive
  • Clearly delineate ROW, installing bollards and painting curb
  • Install striping
  • Install signage
slide23

Next Steps

  • Complete design
  • Coordinate with CPUC and jurisdictions
  • Construct improvements
  • Monitor intersections after construction
