Equipment Package: Roadway Probe Beacons

Description: This equipment package monitors traffic and road conditions by collecting information from passing vehicles that are equipped with a transponder or other short range communications device. The probe data collected by this equipment package may include link travel times, average speeds, road conditions, and any other data that can be measured and communicated by passing vehicles. This equipment package consists of roadside equipment that communicates with passing vehicles using dedicated short range communications, collects the information provided by the vehicles, and forwards this information back to the Traffic Management Subsystem.

Processes: 1.1.2.6 - Process Collected Vehicle Smart Probe Data
1.1.6 - Collect Vehicle Probe Data
1.1.7 - Collect Vehicle Smart Probe Data
1.2.7.7 - Process Vehicle Smart Probe Data for Output
User Service Requirements: 1.0 - TRAVEL AND TRAFFIC MANAGEMENT
1.6 - TRAFFIC CONTROL
1.6.2 - TC shall include a Traffic Surveillance function.
1.6.2.2 - Traffic Surveillance shall include a data collect function to provide the capability to collect data for determining traffic flow and prediction.
1.6.2.3 - Traffic Surveillance shall include a wide-area surveillance capability to include several jurisdictions.
1.6.2.3.1 - The wide-area surveillance shall gather speed and flow information.
1.6.2.3.2 - The wide-area surveillance shall cover a large number of roadway segments.
1.6.2.4 - TC shall provide the capability to acquire detailed traffic measurements at specific locations.
1.6.2.4.1 - Traffic Surveillance shall include a data process function to process the traffic data which are acquired.
1.6.2.5 - The wide area surveillance shall acquire sufficient data to provide the system with the knowledge of the existing conditions.
1.6.2.5.1 - The data process function shall combine and process traffic data from multiple sources and times in order to improve the accuracy of the view of the current traffic condition.
1.8.2 - TDM shall include a processing function.
1.8.2.10 - The processing function's dynamically generated management and control strategies shall include the parking management and controls to include, but not be limited to, the following:
1.8.2.10(b) - Allocation to selected vehicles.

1.9.2.1 - RPA shall be capable of detecting the level of emission of ozone precursors with a high degree of accuracy.
1.9.2.1.3 - RPA shall be capable of reading suitably equipped vehicle's diagnostic data to determine that vehicle's operational status.
8.0 - MAINTENANCE AND CONSTRUCTION MANAGEMENT
8.1 - MAINTENANCE AND CONSTRUCTION OPERATIONS
8.1.2 - Maintenance and Construction Operations shall provide a Roadway Management (RWM) function to monitor traffic, road surface, and environmental conditions and forecast traffic and road surface conditions to support management of routine and hazardous road condition remediation and to communicate changes in conditions. This function includes interactions among Traffic Managers, Supervisors, Dispatchers, Field Crews, Construction Crews, Asset Managers, Planning Agencies, and Weather Services Organizations.
8.1.2.1 - RWM shall support a number of different services, including but not limited to:
8.1.2.1(e) - Repair activities
