  expansion (C03) suggestions needed for cases
• Contributions of operations, technology, design
  (C05) need data sources on arterial flow

Highlights-Safety

• Finalize sample design driver and vehicles
  factors (S05)
• Selection of sites for field study (S07)
• Urban, rural, suburban
• Weather, topography, design factors
• Other data sources
• Qualified contractors
• Rodeo to test roadside/roadway data collection
  capabilities (S03/S04)

10
SHRP 2 Reliability Research

• reduce congestion through incident reduction,
  management, response, and mitigation
• 18 million 12 projects

11
Reliability
Performance Measures

• Travel Time Variability
• Travel time index Average travel time/free-flow
  travel time
• Planning time index 95th percentile travel time
  index
• Buffer time time added to trip to arrive within
  a window with acceptable probability
• Buffer index (mean 95 percentile)/mean

12
Traffic Math 10175 vs. 90 Minutes Clearance
TimeExplaining the Value of 15 Minutes Saved

• Example
• I-5 northbound, Fife vicinity
• Average 8 trucks
• Two (of four) lanes blocked
• 600 a.m., typical Wednesday
• 14 - 18/hour Auto Delay Cost
• 56/hour Truck Delay Cost
• Cost savings of clearing 15 minutes faster
