Description of Problem & Solution

Problem

  • Over 17% of all traffic fatalities involve pedestrians
  • Bicyclists constitute 1% of all trips but 2% of all traffic fatalities

Solution

  • Address both safety and mobility issues pertaining to vulnerable road users
  • Use connected vehicle and autonomous vehicle technology & smart phone

applications

Feasibility for Adoption

  • Aligns with the Florida’s existing Pedestrian and Bicyclist Strategic Safety Plan
  • Generic enough to be adopted by agencies within and outside Florida

SLIDE 5

Scenario B: Vehicles are aware

  • f the presence of bicyclists,

and are yielding to bicyclists

slide-6

Scenario C: Bicyclists are Given the Right-of-way When There are No Vehicles in the Conflicting Approaches

Green is extended for approaching bicyclists

Safety

  • Improved pedestrian/bicyclist detection, verification, validation, and response.
  • Fewer pedestrian and bicycle crashes at signalized intersections.
  • Reduce red-light violations.
  • Help proactively prioritize locations for safety improvements based on conflict analysis.

Mobility

  • Maximizing the available green time and signal phases to accommodate all modes.
  • Reduced delay and number of stops for bicyclists.
  • Increasing the throughput of bicycles and vehicles due to advanced detection.
  • Accommodating higher pedestrian volume particularly in downtown.

Enforcement

  • Future enhancement: An additional detection system that will determine the at-fault road

user and issue a ticket.
