The California Department of Transportation’s (Caltrans) District 7 is to deploy an advanced Arterial Management System (AMS) along a section of the Pacific Coast Highway (PCH) that is part of State Route 1, which will be a critical element of the agency’s Dynamic Corridor Congestion Management (DCCM) program.
Caltrans District 7, in conjunction with its multidisciplinary engineering consultant, Parsons, is implementing the new AMS at 91 signalized intersections on the PCH and parallel arterial routes from I-105 to I-110. The trailblazing project will make use of Sensys Networks’ SensTraffic IoT (Internet of Things) traffic data and analytics platform and SNAPS server software architecture to obtain a host of performance measures on the arterials, including Level-of-Service, travel-time variability/reliability, and intersection queue length.
As a result, the platform will provide real-time assessments of the arterial system’s performance and enable signal timing change to accommodate unforeseen events on the adjacent freeway or the arterial system. The system will also broadcast recommended routes and predictive travel times to roadway users through the use of dynamic message signs (DMS) and online applications.
The SensTraffic platform provides high-resolution performance measures, automated statistical processing of a wide variety of precise traffic detection data, and remote network monitoring and diagnostics. The platform is available with a variety of optional modules, including:
SensMetrics, which uses high-resolution data and analytics to optimize traffic signal timing and safety;
SensID, which uses wi-fi/Bluetooth MAC address re-identification for travel times, intersection delay, and origin/destination analysis;
SensFlow, which provides accurate volume, occupancy and speed reports, including vehicle miles travelled (VMT) and vehicle hours travelled (VHT);
SensDiag, which offers complete remote network diagnostics monitoring and life-cycle management of the traffic detection system;
SensBike, which gives accurate real-time bicycle counts, including non-ferrous bike frames.
“We are especially proud of our involvement in our home state in this advanced AMS project with Caltrans and Parsons,” said Amine Haoui, CEO for Sensys Networks. “This particular implementation leverages the full capabilities of our IoT and data analytics platform, and is an excellent example of how our systems are enabling smart city solutions to deliver measurable benefits to the traveling public.”
Dan Lukasik, Parsons vice president, noted, “Intelligent transportation systems increase capacity, efficiency and safety for motorists. This important project will collect and manage the data and performance measures that will allow our ITS systems to maximize mobility and minimize the impact of traffic incidents.”
