Developing Consistency in ITS Safety Solutions – Intersection Warning Systems E N T E R P R I S E Project Overview December 2011
Agenda • Project scope • Design and evaluation guidance • Roadmap to standardization • Questions E N T E R P R I S E
Project Scope Bring together organizations that have developed and deployed intersection warning systems to develop a consistent approach for accelerated, uniform deployment and further evaluation of intersection warning systems, and to recommend preliminary design and evaluation guidancefor MUTCD consideration. E N T E R P R I S E
Project Scope • Anticipated results • Increase awareness of systems deployed • Develop design guidance to support accelerated and more consistent deployment • Establish evaluation framework • Create roadmap for reaching standards in MUTCD and Highway Safety Manual E N T E R P R I S E
Project Scope • Webinar (June 23) • Shared knowledge and educated each other on systems deployed • Missouri, North Carolina and Minnesota • Identified challenges with future deployments • Warrants/Function • Liability • Placement • Failsafe/Reliability • Design • Capital and Operating Costs • Effectiveness • Connected Vehicle • Quality Control E N T E R P R I S E
Project Scope • Workshop #1 (July 28-29) • Discussed content of a preliminary standard • Shift to design and evaluation guidance • Discussed roadmap for reaching standardization • Engage further human factors research • Support further evaluation across state boundaries • Identify what may be required for interim compliance with existing MUTCD standards • Allow for continued deployment and evaluation • Brief the NCUTCD and AASHTO SCOTE to initiate formal processes E N T E R P R I S E
Project Scope • Workshop #2 (September 15-16) • Review preliminary design guidance • Develop an evaluation framework that may be used in future deployments • Establish measures of effectiveness and data needs for each system type to facilitate comparison of systems • Discuss plans for future deployment and coordination plans • Refined roadmap for standardization E N T E R P R I S E
Design and Evaluation Guidance • Introduction • Purpose • Typical system components • Glossary of terms
Design and Evaluation Guidance • Design guidance • Four typical layouts based on warning direction and intersection configuration • Preliminary illustrations • Offer technical insight and recommended practice • Do not limit engineering judgment or agency discretion • Conditions, intended driver use, layout, options, notes and references • More details conditions (warrants) • Anticipated benefits and costs E N T E R P R I S E
Design and Evaluation Guidance • Evaluation guidance • Not all systems have been formally evaluated • Acknowledged various evaluation approaches • Establish a common framework for evaluation • Individual and national • Based on ITS Evaluation Guidelines • Goal • Strategy • Hypotheses • Test plan parameters E N T E R P R I S E
