Ohio DOT Portable Freeway Management System
Status
Planned
Description
This system is a "virtual" TMC that allows direct control of freeway field equipment (e.g., variable message signs) from remote locations, using simple equipment (e.g., a laptop computer.) Can be used for portable workzone applications.

Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| MCM Work Zone Management | 'MCM Work Zone Management' remotely monitors and supports work zone activities, controlling traffic through dynamic message signs (DMS), Highway Advisory Radio (HAR), gates and barriers, and informing other groups of activity (e.g., traveler information, traffic management, other maintenance and construction centers) for better coordination management. Work zone speeds, and delays, and closures are provided to the motorist prior to the work zones. This application provides control of field equipment in all maintenance areas, including fixed and portable field equipment supporting both stationary and mobile work zones. | False |
|---|
| Roadway HOV Control | 'Roadway HOV Control' monitors and controls high occupancy vehicle (HOV) and high occupancy toll (HOT) lanes. It includes traffic sensors that monitor HOV lane usage and display equipment such as lane control signals that provide lane status to drivers. | False |
|---|
| TMC In–Vehicle Signing Management | 'TMC In–Vehicle Signing Management' controls and monitors RSEs that support in–vehicle signing. Sign information that may include static regulatory, service, and directional sign information as well as variable information such as traffic and road conditions can be provided to the RSE, which uses short range communications to send the information to in–vehicle equipment. Information that is currently being communicated to passing vehicles and the operational status of the field equipment is monitored by this application. The operational status of the field equipment is reported to operations personnel. | False |
|---|
| TMC Reversible Lane Management | 'TMC Reversible Lane Management' remotely monitors and controls reversible lanes. It provides an interface to reversible lane field equipment (traffic sensors, surveillance equipment, lane control signals, physical lane access controls, etc.) and to traffic operations personnel to support central monitoring and control of these facilities. | False |
|---|
| TMC Work Zone Traffic Management | 'TMC Work Zone Traffic Management' coordinates work plans with maintenance systems so that work zones are established that have minimum traffic impact. Traffic control strategies are implemented to further mitigate traffic impacts associated with work zones that are established, providing work zone information to driver information systems such as dynamic message signs. | False |
|---|
| Traveler Trip Planning | 'Traveler Trip Planning' provides a personalized trip plan to the traveler. The trip plan is calculated based on preferences and constraints supplied by the traveler and provided to the traveler for confirmation. It represents kiosks and other fixed public interactive displays that may be used by travelers in public areas. | False |
|---|
| Vehicle Roadside Information Reception | 'Vehicle Roadside Information Reception' receives advisories, vehicle signage data, and other driver information and presents this information to the driver using in–vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information. | False |
