Texas – I-35 Connected Work Zone Workshop

Some documents are made available in PDF format. You will need Adobe Reader to view them.

The Texas A&M Transportation Institute (TTI), the Texas Department of Transportation (TxDOT), the Federal Highway Administration (FHWA), Southwest Research Institute (SwRI), VOLPE, and the Crash Avoidance Metrics Partnership (CAMP) held a 3-day meeting/workshop on March 26-28, 2018. The objective of the workshop was to 1) provide project updates and generate technical discussion by all agencies involved in the I-35 Connected Work Zone demonstration project, and 2) gain feedback on an effort to develop a decision-support tool framework to help infrastructure owner-operators (IOOs) evaluate V2I applications for their needs.

March 28, 2018 Wrap-Up

Key Takeaways:

• The level of mapping detail that an IOO can likely provide is very different than the level of detail desired by original equipment manufacturers (OEMs). Until techniques and information availability advance, a disparity between practical and preferred exists.
• There are various levels of resolution possible for mapping work zone locations for connected vehicle applications. CAMP has come up with a procedure that has been shown to work and will be demonstrated on I-35. SwRI is working on integrating data and processes to get data to/from roadside units (RSUs) and create a map.
• The potential for TxDOT to come up with a smart cone specification that could automatically map itself and talk to roadside units (RSUs) in a connected vehicle environment could eventually evolve into a national methodology. It may be worth discussing this idea with the connected-vehicle pooled-fund study members and technology vendors to see if interest exists.
• The framework for evaluating potential V2I benefits still needs stakeholder review and comment to ensure it will provide information useful to agencies. A question that remains is whether the pieces of the framework can be built iteratively.
• Measuring performance of connected vehicle technologies will be key to assessing benefits and supporting the business case for future development and deployment.
