Physical Object: Connected Vehicle Roadside Equipment

RSE Intersection Safety

Overview

'RSE Intersection Safety' uses short range communications to support connected vehicle applications that improve intersection safety. It communicates with approaching vehicles and ITS infrastructure to alert and warn drivers of potential stop sign, red light, and non-motorized user crossing conflicts or violations.

This functional object is included in the "Connected Vehicle Roadside Equipment" physical object.

This functional object is included in the following service packages:

This functional object is mapped to the following Functional View PSpecs:

Requirements

# Requirement
01 The roadway equipment shall collect the current location (latitude, longitude, and elevation) from personal information devices.
02 The roadway equipment shall communicate with approaching vehicles to alert and warn drivers of potential stop sign, red light, and non-motorized user crossing conflicts or violations.
03 The roadway equipment shall collect vehicle path information sent by a vehicle.
04 The roadway equipment shall provide current crossing status including permission to cross, crossing time remaining.
05 The roadway equipment shall send to Connected Vehicles intersection signal timing information in order for the vehicle to determine if it will safely cross the intersection given its current speed and location.
06 The roadway equipment shall send to connected vehicles a warning if an intersection violation appears to be imminent.
07 The field element shall collect current conflict monitor and intersection control data from the traffic signal controller.
