Connected/Automated Vehicles Resources

The Institute of Transportation Engineers, on behalf of the Roadside Unit (RSU) Standardization Working Group is pleased to announce the publication of RSU Standard Version 1.0, also known as Connected Transportation Interoperability (CTI 4001 v01.00). The RSU Standard is a non-proprietary, technology neutral, industry-based consensus standard for roadside units, based on stakeholder inputs and existing resources such as the RSU Specification Version 4.1, NEMA's TS-10 Connected Vehicle Infrastructure – Roadside Equipment Standard as well as lessons learned from pilot deployments. The RSU Working Group accomplished this effort with broad stakeholder representation including standards development organizations (SDOs), infrastructure owner operators (IOOs), automotive original equipment manufacturers (OEMs) and suppliers, infrastructure equipment vendors, security specialists, Intelligent Transportation Systems (ITS) integrators, and end-users of data and services

The Institute of Transportation Engineers (ITE), on behalf of the Connected Intersections Project Committee, is pleased to announce the publication of the Connected Intersections (CI) Implementation Guide, known also as Connected Transportation Interoperability (CTI 4501 v01.00). This initial version of the CI Implementation Guide provides a detailed interface specification that can be used by the ITS community to deploy a nationally interoperable, openly available broadcast providing traffic Signal Phase and Timing and associated required mapping ("MAP") information that can be received by connected vehicles and other interested participants in the transportation system. This information enables applications such as Red Light Violation Warning and others that can increase both safety and efficiency. The Connected Intersections Project Committee accomplished this effort with broad stakeholder representation including standards development organizations , Intelligent Transportation Systems (ITS) infrastructure owner operators (IOOs), automotive original equipment manufacturers and suppliers, infrastructure equipment vendors, security specialists, ITS integrators, and end-users of data and services.

The 2021 ITE Developing Trends Report represents collective input from ITE Councils and Standing Committees on emerging transportation challenges and solutions. The report covers transportation planning, engineering, management, and operation advancements and will benefit the industry's leaders and professionals in the public and private sectors. The Developing Trends Report Task Force reached out to all ITE Councils and Standing Committees to identify trends relevant to their scope and expertise.

The individual LEDs or blocks of LEDs in a display rapidly flash on and off at a rate invisible to the human eye. In some full color matrix displays that contain Red, Green, and Blue (RGB) LEDs, the individual colors flash on and off at different rates. Many TCDs (DMS, traffic signals, and railroad flashers) use LEDs with refresh rates that cycle at 60-240 Hertz (Hz). This has created an emerging issue with sensor technology being used for detection in certain automated vehicles. Automated Driving Systems (ADS) cameras are a sensor component capable of detecting an electronic display TCD and recognizing the message provided.

By automating vehicle speed regulation, improving reaction times, and reducing or eliminating the incidence of distracted and/or impaired driving, AVs have the potential to support several of the core elements of the Safe System Approach. However, transportation professionals need to work with policymakers and vehicle companies toward policy, legislation, and vehicle and software design that create safe AVs and safe streets to operate them on. In combination with street design and built environment strategies, targeting AV speed--which is a critical factor in determining collision severity--will be an important safety strategy in the future.

During the past decade, the potentials of vehicle automation have become one of most exciting transportation topics, prompting both public and private sectors to invest significant resources toward research and development. For a number of years, the focus of automated vehicles (AVs) has been on the optimization of system performance and the creation of self-driving cars. These efforts have resulted in a variety of technologies that are available in many new vehicles.

Connected Vehicles Deployment Benefits

The USDOT's recent award of $60 million in Automated Driving Systems grants solidified the notion that we've moved beyond simple demonstrations for these types of deployments, especially with Autonomous Vehicle (AV) shuttles. Available AV shuttles on today's market typically accommodate six to 12 passengers in a vehicle that either resembles an elongated golf cart or a small transit vehicle.

As a part of its mandate to serve its membership, ITE is advancing knowledge, providing guidance, and instilling the spirit of workforce development in all aspects of transportation technology advancements. As part of ITE's Connected and Automated Vehicle (CAV) Institute Initiative, a joint Steering Committee on CAV was formed. Some of the objectives of this CAV Steering Committee include: advocating for the policy and governance elements; providing guidance on technology deployments; documenting the lessons learned; discussing topics of interest to the practitioners; and speaking for the membership on policy, education, outreach, national standards, rule-making, and more.

The transportation industry is on the verge of the largest disruption since the invention of the automobile.
