IMPROVING HIGHWAY SAFETY WITH ITSExecutive Summary NHI Course No. 137044
Why Attend Course • Increase awareness of deploying ITS to improve highway safety • Accelerate the introduction of ITS applications into traditional safety projects • Increase recognition of the contribution ITS can make in improving highway safety
Purpose of CourseDevelop Collaboration and Coordination • Increase awareness of ITS applications among safety professionals • Identify opportunities for collaboration between Safety and ITS personnel • Reinforce shared goals and objectives • Accelerate the introduction of ITS applications in traditional safety approaches
Course Goals • Provide participants with basic tools and resources • Discuss specific actions • Identify “Out of the Box” innovative approaches • Provide participants direction for finding more information
Audience • Safety and ITS Professionals • Planners and Designers • Operations and Maintenance Staff • State DOT, MPO, city and county agencies • Contractors who provide services to state and local agencies
Format • 2 Day Course • 5 Lessons • Presentation/mini-lectures • Open discussion – local issues • Case Study • 6 Interactive activities • Fishbowl Exercise • Small group activities • Individual action plan
4.9 persons killed every hour • 42,643 in 2003 (compared to 58,000 U.S. fatalities during 8-year Vietnam war) • 330 persons injured every hour • 2.9 million injuries in 2003
Average Day • 117 fatalities a day • 30% of daily fatalities (35) are under the age of 25 • Daily financial loss is $630 million
FHWA Safety Goal • Reduce roadway fatality rate from 1.5 per million VMT in 2001 to 1.0 by 2008 • Highway Safety must be improved, and ITS has the potential to help
Sample Safety Goals • Reduce vehicle, bicycle & pedestrian fatalities • Improve the safety of highway-railroad crossings • Improve the safety of commercial vehicle operations • Minimize incident response times • Improve data & decision support systems • Reduce intersection, pedestrian, and/or roadway departure crashes
Course Topics • Improving Safety with ITS • Work Zone Case Study • Nominal Vs. Substantive Safety • Safety Strategic Planning and ITS Deployment Process • Safety and ITS Collaboration • Organizational and Individual Level Action Plans
ITS Definition Intelligent Transportation Systems (ITS) means electronics, communications, or information processing used singly or in combination to improve the efficiency and/or safety of a surface transportation system. 23 CFR Part 940
Intersections & Interchanges Pedestrians & Bicycles Highway-Rail Grade Crossings Road Weather Other Adverse Roadway Conditions Speed Management Work Zones Incident Response & Mitigation Public Transportation Archived Information Management 10 Places ITS Improves Safety
Case StudyBig-I Project Characteristics • Two-year interchange rebuild project • Intersection of two Interstates • ADT - 300,000 vehicles • 111 lane-miles of construction • 45 new and 10 rehabilitated bridges
Big-I Work Zone Safety Challenges • Traffic pattern changes • Nighttime closures • Alternate routes • Information on travel route availability • Potential for extreme congestion • Incident management in work zone
Traditional Approaches • Advanced Signing • Cones/Barrels • Barriers • Detour Signing • Temporary Pavement Markings • Nighttime Lighting
Big-I Work Zone – ITS Applications • Traffic Management Center (TMC) • Incident detection using cameras & sensors • Traveler information disseminated over multiple outlets • Incident response using motorist assistance vehicles
Big-I Work Zone – ITS Benefits • NO FATALITIES • Reduced crashes & secondary crashes by 32% • Reduced incident management times from 45 to 25-mins • Saved effort through automation • Reduced traffic through work zone • Identified & responded to areas that were difficult to navigate
Nominal vs. Substantive Safety • Nominal Safety • Compliance with standards, warrants, guidelines & sanctioned design procedures • Substantive Safety • Involves pro-active enhancements • Employs available resources, including technology, design, maintenance, enforcement & emergency services
Nominal Safety Example – Sharp Curve After Long Tangent • Curve Design Speed of 35 mph is acceptable • But speed differential value >12 mph is known to pose high safety risk of 10%+ higher crash rates
Moving Toward Substantive Safety • Work to understand the context of hot-spots • Develop pro-active system-wide safety enhancements that help prevent crashes • Use data to help predict potential problems • Employ all available resources, including technology, design, maintenance, enforcement, & emergency services
How ITS SupportsSafety Countermeasures • Enhance safety solution • Facilitate data collection & performance measurement • Enable automated enforcement • Enable real-time performance monitoring
Designing ITS-Supported Countermeasures • Identify: • Safety challenge • Performance measures & data requirements • Institutional issues • Traditional approaches to address challenge • ITS to support traditional approaches • Form: • ITS-supported countermeasure
Strategic Planning/ITS Deployment • Safety Strategic Plan • ITS Deployment Process • Synergies between them
How Does Safety & ITS Collaboration Help? • Collaboration will help: • Identify ITS for highway safety challenges & data collection needs • Focus the deployment of ITS to improve system-wide highway safety (beyond the hot spots) • Develop new ITS applications for regional & statewide safety challenges
Course Activities • Identify Safety Challenges • Safety Priority Area Voting • Develop ITS-Supported Countermeasures • Develop Collaborative Action Plans
