Regional Arterial Traffic Performance Measurement System (RATPeMS)

 

Location

The RATPeMS project has developed a Level of Service (LOS) model for 157 signalized intersections within the City of Glendale, creating an arterial traffic performance measurement system that allows for real-time operation timing.” This revision adds some clarity by specifying that the LOS model is for signalized intersections within the city and emphasizes the creation of the traffic performance measurement system.

Description

The RATPeMS project has successfully developed a Level of Service (LOS) model for 157 signalized intersections within the city, transforming them into an advanced arterial traffic performance measurement system that enables real-time operation timing. Additionally, the project has implemented a cutting-edge fiber optic system called the State-of-the-Art Iteris Vantage Next video detection system at multiple locations, seamlessly connecting them to the City’s Traffic Management Center (TMC). This system provides real-time updates on corridor conditions and performance metrics, which are accessible through a user-friendly web-based interface.

To achieve our goals of enhancing safety, preserving infrastructure, and promoting sustainability, the project addresses the communication infrastructure gaps along major city corridors. It integrates a powerful Synchro Model as a performance measurement tool. This sophisticated system collects real-time data from intelligent transportation systems, including vehicle sensors and traffic signal systems, storing it permanently in a data warehouse. This valuable information is then presented in various formats, catering to traffic managers, engineers, planners, and researchers. Ultimately, RATPeMS provides the City with a comprehensive toolset for evaluating the impacts of operational changes, enabling better resource management, and assessing the achievement of established goals.
Our partnership with the Los Angeles County Metropolitan Transportation Authority (Metro) has been instrumental in the success of RATPeMS. Metro issued a “Call for Projects,” inviting local agencies to submit funding applications for various transportation improvements, including Intelligent Transportation System projects. The City submitted an application, which received approval for a Proposition C Discretionary grant fund from Metro, amounting to $530,869. This funding supported the design and construction of the Regional Arterial Traffic Performance Measurement System project, an integral component of the City’s Traffic Management Center (GTMC). It also provides real-time access to multiple stakeholders across jurisdictional boundaries through the Los Angeles County Information Exchange Network (IEN), a unique and vital aspect of the project benefiting multiple agencies.
As part of the RATPeMS project’s commitment to continuous improvement, ongoing data analysis is conducted to identify potential enhancements and optimizations. Regular reports and performance evaluations are shared with the City’s Traffic Management Center and other relevant stakeholders to ensure that the system continues to meet its objectives efficiently. This data-driven approach allows for informed decision-making and the ability to adapt to changing traffic patterns and emerging technologies.

The City of Glendale has already experienced tangible benefits from the implementation of RATPeMS. These include cost savings and streamlined signal maintenance operations. Additionally, the public has benefited from reduced signal-related travel delays, shorter travel times, lower greenhouse gas emissions, and improved overall public safety.
Furthermore, the RATPeMS project fosters collaboration and knowledge sharing within the transportation community. It actively engages with industry experts, researchers, and transportation agencies to exchange best practices and explore innovative solutions. This collaborative effort not only benefits the City of Glendale but also contributes to the broader field of intelligent transportation systems, making a positive impact on traffic management and urban mobility on a regional and national scale.
