Roadway Equipment Coordination Equipment Package

Description:

This equipment package coordinates field equipment that is distributed along the roadway by supporting communications directly between the field equipment. This includes coordination between remote sensors and field devices (e.g., Dynamic Message Signs) and coordination between the field devices themselves (e.g., coordination between traffic controllers that are controlling adjacent intersections.).

1.6.3.3.2	Device Control shall include the capability to dynamically control traffic signing.
1.6.3.3.3	Device Control shall include the capability to control freeway ramp metering.
1.6.3.4	Device Control shall communicate control data to the following devices.
1.6.3.4(b)	Ramp meters.
1.6.3.4(c)	Information signs.
1.7	INCIDENT MANAGEMENT
1.7.1	Incident Management shall provide an Incident Identification function to identify incidents.
1.7.1.1	The Incident Identification function shall include the capability to identify predicted incidents.
1.7.1.1.1	The Incident Identification function shall use information from the following types of sources, where available, to identify predicted incidents:
1.7.1.1.1(a)	Traffic flow sensors.
1.7.1.1.1(b)	Environmental sensors.
1.7.1.1.1(g)	Sponsors of special events.
1.7.1.2	The Incident Identification function shall include the capability to identify existing (both planned and unplanned) incidents.
1.7.1.2.1	The Incident Identification function shall use information from the following types of sources, where available, to identify existing incidents:
1.7.1.2.1(b)	Environmental sensors.
1.8.2	TDM shall include a processing function.
1.8.2.1	The processing function shall provide the capability to generate management and control strategies that facilitate the implementation of policies and regulations designed to address the following:
1.8.2.1(e)	Air pollution/emission information and detection.
