In 2015, Caltrans was awarded $6.5 million in funding through LA Metro’s Call for Projects. A year prior, Caltrans received over $24 million in State Highway Operation and Protection Program (SHOPP) funds for the freeway improvements.
The Call for Projects funding, together with the SHOPP funding, is being used to improve the infrastructure on both the arterials and freeway, and ensure a robust corridor management program can be implemented. Infrastructure improvements include:
- Installing CCTV cameras and changeable message signs
- Upgrading traffic signal controllers and detection at various on and off ramps
- Replacing loop detectors for the ramp meters and vehicle detection stations
- Modifying a traffic signal system in Duarte and installing new wireless broadband communication to the LA County system (and bringing other traffic signals in the corridor in Monrovia, Duarte, and LA County onto the County network)
- Installing Bluetooth devices to supplement existing arterial coverage to improve travel time information on the arterials
- Installing traffic signal firmware, controller, or cabinet upgrades; and video cameras for traffic detection
- Deploying a motorist guidance signing system on the arterials to dynamically assist motorists in navigating through detours during major incidents or events
- Adding roadside environmental stations for monitoring and evaluating air pollutants
- Adding information-sharing equipment between traffic management and transit operations for Foothill Transit and Pasadena Transit
Twenty-eight arterials were studied and identified as arterials for these improvements, including Mountain Street, Fair Oaks Avenue, Corson Street, Lake Avenue, Sierra Madre Boulevard, Huntington Drive, Duarte Drive, Santa Clarita, Myrtle, and Buena Vista.
