About the Webinar:
The Urban Mobility Report (UMR) has been providing information on urban congestion levels in the U.S. for more than three decades. The UMR uses private-sector crowdsourced speed data combined with traditional public-agency roadway inventory data to measure mobility conditions. The current UMR statistics describe overall congestion levels, but do not classify causes of congestion. With the advent of improvements in the third-party provider data stream, it is now possible to quantify at least some aspects of the mobility contribution provided by traffic signals. This project used detailed crowdsourced travel time data collected by a private-sector vendor (INRIX) to report on the performance of traffic signals for a proof of concept of evaluation at the corridor, urban area, and statewide levels.
Researchers reviewed and quantified signal operations for urban areas by evaluating signal operations metrics obtained from crowdsourced data, such as arrivals on green and split failures. In addition, an index metric (traffic signal efficiency index) was used to assess overall quality of traffic signal progression. These new data enhance evaluations that can be obtained from traditional metrics such as arterial street delay. Urban areas were categorized using population and traffic signal density to ensure that any comparisons include contextual elements that are key to decision-maker understanding and messaging strategies.
About the Presenter:
Mr. Luke Albert is an Associate Research Engineer with broad experience in traffic operations and transportation engineering. He worked as a private transportation engineering consultant for almost 7 years and as a City Traffic Engineer for over 13 years. As the City Traffic Engineer in Goodyear, Arizona, he oversaw traffic management, traffic operations, pavement management, street maintenance, and street sweeping divisions. He is a champion of enhancing traffic signal operations through technology, and oversaw the installation of approximately 50 miles of fiber optic communication that connected the City’s traffic signals to the Traffic Management Center. He is a registered professional engineer in Arizona and Texas and is also registered as a Professional Traffic Operations Engineer.
Ms. Debbie Albert is an Associate Research Engineer with over 20 years of municipal experience. While working for the City of Glendale in Arizona, she served the last four years as the City Traffic Engineer providing management and direction for all traffic engineering and operations functions as well as coordinating regional transportation projects affecting the city. During her tenue with Glendale, she led various efforts in the areas of intelligent transportation systems, public engagement and special event traffic management, focusing on the efficient flow of traffic in Arizona’s fifth largest city. Specifically, she was responsible for development and implementation of a citywide intelligent transportation system including fiber optic cable communications, traffic monitoring cameras, dynamic message signs and a state-of-the-art traffic management center. She coordinated the transportation management plans for professional hockey, baseball and football facilities anchored by a $1 Billion mixed-use development entertainment, dining and retail development. Over her 20-year career, she also engaged the public on neighborhood traffic concerns, specific high-profile projects including a light rail transit line and with various city Boards and Commissions.
Mr. Kartik Jha is an Associate Transportation Researcher at TTI in College Station, Texas, where he has been involved in urban mobility measurement, freight mobility, project prioritization and special event traffic management projects. He has helped with research in areas involving exploration and application of travel time databases, system performance measurement for FHWA pooled fund study, best practices for public transportation agencies, travel data quality assessment for low-volume roadways, utilizing NPMRDS for MAP-21 performance monitoring, as well as using FAF database to determine value of truck freight flow between urban regions and on US roadways. His areas of interest lie in transportation statistics and transportation system performance monitoring. Prior to joining TTI, Mr. Jha worked as a highway design engineer with a design consultancy in India. During this time, he also gained some experience in projects in the areas of transportation planning, survey optimization and city transit planning.
