CONNECTED MARYSVILLE

THE WORLD'S FIRST FULLY CONNECTED CITY

As a component of the 33 Smart Mobility Corridor project, the City of Marysville is upgrading all 27 traffic signals in the City and equipping them with Dedicated Short Range Communication (DSRC) radios to be used as Road Side Units aimed at delivering Signal Phase and Timing data and other safety messages to vehicles that have been outfitted with On Board Units (OBUs).

 

In addition to the deployment of traffic signal upgrades, project partners have also committed to equipping at least 1,200 vehicles with OBUs. The goal is to create a real-world environment where companies, governmental agencies, and academia can develop and test smart technology throughout the entire City in a real life environment.

Why Marysville?

The City of Marysville is located in the heart of Ohio’s 33 Smart Mobility Corridor. Through the support of the Ohio Department of Transportation and multiple partners, in 2019, the installation of 432 strands of redundant fiber along US-33 and Industrial Parkway will be completed. This fiber network will allow the City to connect each of its 27 traffic signals for the testing of AV/CV technologies. Additionally, 67 DSRCs will be installed along US 33, allowing for off-the-road testing at the Transportation Research Center and on-the-road testing in rural, suburban, and urban environments throughout the corridor. As a smaller community with lower traffic volumes, Connected Marysville will allow >10% penetration rate with at least 1,200 vehicles equipped with on-board units. As a result, the connected vehicles will have a greater saturation of the local traffic network than if they were in a larger community. This, and the presence of several smart mobility and automotive assets in the community, allows for the “right size” design of new technologies.

Future Applications

Connected Traffic Signals: A device is installed in signal cabinets and collects real time signal timing data. The device will have access to individual vehicle speeds, classification, positions, arrivals rates, acceleration/deceleration rates, and queue lengths. The data is then sent to a server using a 4g LTE cellular network. The data is made available to a cell phone app or in-car display which will assist drivers with making better decisions. Various OEMs have incorporated this technology in their new vehicle models. 

Vehicle Platooning: Vehicle platooning is a group of vehicles that can travel very closely together, safely at high speed. Each vehicle communicates with the other vehicles in the platoon. There is a lead vehicle that controls the speed and direction, and all following vehicles (which have precisely matched braking and acceleration) respond to the lead vehicle’s movement. As technology advances, eventually self-driving or autonomous vehicles will be able to automatically join platoons that may function like long trains of vehicles on a highway. Platooning will ease traffic congestion, advance highway safety, and make travel and energy consumption more efficient.
