Agencies are developing and using simple innovations for Intelligent Transportation System (ITS) technologies and processes. For example, Illinois DOT repurposed an over height detector for use as counter for trucks. In Iowa an automated process is being developed for video requests. The purpose of this project is to learn and share simple innovations used in ITS.
Current
Administration of Communications
State departments of transportation (DOTs) have various models for deploying and administering communications infrastructure to support ITS networks, some utilizing public-private partnerships, leasing, asset sharing, resource trading, or other approaches. ENTERPRISE members are interested in reducing costs and improving efficiencies as they administer communications infrastructure. This project is investigating how State DOTs may reduce costs and increase efficiencies for installing and managing infrastructure for multiple, redundant communications networks. The project will gather examples of various communications administration models and document case studies from selected State DOTs.
Potential Approaches for Wrong-Way Driving Applications – Phase 2
Wrong-way driving (WWD) is a growing concern on roadways, as the resulting crashes tend to be severe and often result in fatalities and serious injuries. Transportation agencies are deploying on-road countermeasures such as low-mounted Wrong Way signs, pavement marking improvements, detection-activated signs, but these countermeasures can only go so far to reduce wrong-way crashes.
Advancements in cooperative automated technologies will enable significant possibilities to provide WWD warnings through in-vehicle navigation systems and smartphone-based mobile applications. These types of interventions could supplement on-road countermeasures by influencing wrong-way drivers to correct their wrong-way movements while also alerting other nearby drivers. Many transportation agencies have installed on-road sensors that detect wrong-way vehicle movements and communicate WWD events to traffic management centers. In addition, public safety agencies also become aware of wrong-way drivers through calls from nearby motorists.
A national approach to consistently communicating WWD events would enable data from multiple sources (e.g., 911 calls, on-road sensors, self-reporting mobile applications) to become available through one or more data feeds for in-vehicle mechanisms to access and provide alerts to errant drivers and nearby motorists.
This ENTERPRISE project is expanding outreach efforts begun in the ENTERPRISE Potential Approaches for Wrong-Way Driving Applications project and promoting the concept of a national approach for communicating wrong-way driving event information.
