City of Riverside Innovation Corridor

The City of Riverside Innovation Corridor is a six-mile section of University Avenue between University of California, Riverside and downtown Riverside. This area was selected due to the its proximity to an expanding transit and alternative transportation network, research institutions associated with UCR, and the ever-expanding entertainment destinations in the downtown region, as shown in Figure 1. Along the corridor, all traffic signal controllers are being updated to be compatible with SAE connectivity standards. Dedicated Short Range Communication (DSRC) roadside-units are mounted along with each traffic signal. Signal Phase and Time (SPaT) messages are directly transmitted to the DSRC units and forwarded to the vehicles equipped with onboard units. Meanwhile, Radio Technical Commission for Maritime Services (RTCM) and Map messages are broadcasted via DSRC devices to support geofencing and accurate positioning.  The Innovative Corridor will serve as a key testbed in southern California for Connected and Automated Vehicles (CAVs) applications, such as connected eco-approach and departure (EAD), eco-transit operation, smart Intersection management, and other applications to improve safety, mobility and environmental sustainability. Figure 2 shows a photo from an EAD test along the Innovative Corridor. The Digital Visual Interface (DVI) inside the car displays the signal state and countdown information from the through movement at the downstream intersection. A target speed recommendation is also provided based on a digital speedometer to give drivers eco-driving guidance to pass the intersection in the most energy efficient manner.

There are many state-of-the-art elements to the Innovation Corridor that not only address transportation, but also energy and air quality. New generation air quality sensors are planned to be deployed at buses stops, intersections and downwind/upwind of the freeways to evaluate the air quality and health impact of the traffic. A variety of other futuristic elements will also be integrated in the corridor, such as user-focused shared zero emissions mobility services, renewable energy generation and vehicle-to-grid interaction.
