City of Victoria Emissions Monitoring Equipment
City of Victoria ITS Field Equipment
Guadalupe-Blanco River Authority Flood Warning Devices
Lavaca Navidad River Authority Flood Monitoring Devices
Lower Colorado River Authority Flood Detectors
Municipal ITS Field Equipment
TCEQ Field Emissions Monitors

USGS Flood Monitoring System

Functional Requirements:

1The field element shall include sensors (such as traffic, environmental, and work zone intrusion detection sensors) that provide data and status information to other field element devices (such as dynamic message signs, ramp meters, traffic signals, work zone intrusion alert systems), without center control.
2The field element shall include sensors (such as traffic, environmental, and work zone intrusion detection sensors) that receive control information from other field element devices, without center control.
3The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that provide data and status information to other field element devices (such as dynamic message signs, traffic controllers on adjacent intersections), without center control.
4The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that receive control information from other field element devices, without center control.
  

User Service Requirements (fully or partially addressed):

1.0TRAVEL AND TRAFFIC MANAGEMENT
1.2EN-ROUTE DRIVER INFORMATION
1.2.3DI shall provide an In-vehicle Signing capability.
1.2.3.2The DI In-vehicle Signing function shall include a long term capability to serve more of the traveler's needs.
1.2.3.2.3The In-vehicle Signing function shall provide the capability to utilize data from roadside environmental sensors as inputs to warning messages.
1.5.2TSI shall include an Information Access function that allows travelers to access the available information.
1.5.2.5Information Access shall provide the capability for travelers to access the TSI information via any of, but not limited to, the following methods:
1.5.2.5(a)Highway advisory radio.
1.6TRAFFIC CONTROL
1.6.0ITS shall include a Traffic Control (TC) function. Traffic Control provides the capability to efficiently manage the movement of traffic on streets and highways. Four functions are provided, which are, (1) Traffic Flow Optimization, (2) Traffic Surveillance, (3) Control, and (4) Provide Information. This will also include control of network signal systems with eventual integration of freeway control.
1.6.3TC shall include a Device Control function.
1.6.3.3The Device Control function shall provide the capability to exercise control over those devices utilized for traffic control.
1.6.3.3.2Device Control shall include the capability to dynamically control traffic signing.
1.6.3.3.3Device Control shall include the capability to control freeway ramp metering.
1.6.3.4Device Control shall communicate control data to the following devices.
1.6.3.4(b)Ramp meters.
1.6.3.4(c)Information signs.
1.7INCIDENT MANAGEMENT
1.7.1Incident Management shall provide an Incident Identification function to identify incidents.
1.7.1.1The Incident Identification function shall include the capability to identify predicted incidents.
1.7.1.1.1The 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.
1.7.1.2The Incident Identification function shall include the capability to identify existing (both planned and unplanned) incidents.
1.7.1.2.1The 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.
1.8.2TDM shall include a processing function.
1.8.2.1The 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.
5.0EMERGENCY MANAGEMENT
5.1EMERGENCY NOTIFICATION AND PERSONAL SECURITY
5.1.3ENPS shall include a Remote Security and Emergency Monitoring (RSEM) function to create an environment of safety in secure areas.
5.1.3.5RSEM shall include a Physical Security System (PSS) function.
5.1.3.5.4PSS shall warn travelers of impending security system deployment via local information systems.
