Travel Time Reliability -- Reduce the Gap

Unreliable travel conditions
Making Travel More Reliable Has Multiple Benefits
Reducing the effects of events (e.g., traffic incidents, WZs, weather) Provides “double” congestion relief:
More predictable (less variable travel), AND Lower overall delay
Improves safety Duration of motorist exposure to unsafe conditions
reduced Saves fuel Reduces emissions
Unreliable trips valued at a premium by users 2-6X the average for commuters Higher value for freight, especially JIT
Examples of Aggressive Operations Strategies to Improve
System Reliability
Traffic Incident Management
Work Zone Management
Traveler Information
Traffic Incident ManagementAggressive:• Formal regional program with mutual
agreements.• Defined performance goals.• Integrated on-scene activity.
Typical:• Informal, personality-dependent programs.• Agency culture and priorities drive on-scene
operations.• Incompatible communications systems.
Integrated On-Scene OperationsSeattle, WA
• Joint Operations Policy Statement• WSDOT and WSP• 90 Minute Clearance Goal
Work Zone Safety and MobilityAggressive:• Real time traveler information on web sites.• Shorter construction duration and traveler exposure to work zones.• Using ITS applications to improve safety and mobility in work zones.
Typical:• Only general construction information on web sites.• Limited use of innovative construction and contracting strategies designed to reduce project duration.• Minor application of ITS technologies to improve work zone performance.
Albuquerque “Big I” Work Zone ITS
New Mexico used ITS to reduce traffic incident clearance time from 45 minutes in the past to 25 minutes during the project.
ITS Control Center
Coordination with Emergency Services
Traveler InformationAggressive:• Travel times and incident information on DMS. High quality 511 services, including ubiquitous
metropolitan implementation.• High quality, easily accessible, and
understandable information on websites.
Typical:• DMS blank, limited information (e.g., “Congestion Ahead”).• No 511 service.• Out-of-date information on websites.

“Final Word”Can Operations Make a Difference
– YES!What will it take …..
A Comprehensive set of strategies Ownership by all regional stakeholders
Public, businesses, and agencies Aggressively Operate the Transportation
System Proactively and Regionally
Focus on Addressing System Reliability
