COTA Transit Fixed-Route Vehicles

Status

Description

Fixed–route bus service is the backbone of the COTA system. The service includes express, local, crosstown, and neighborhood circulator bus routes.

COTA's computer–aided dispatch and automatic vehicle location (CAD/AVL) system provides dispatchers and supervisors with the capability of tracking the location of the entire fleet in real time. Global Positioning Satellite (GPS) devices placed on each fixed–route, demand–response, supervisor and maintenance vehicle allow dispatchers to track any COTA vehicle at any time. The system, which is integrated with the Franklin County Government's is being updated to the MARCS digital radio system for voice communication. The system sends and receives fleet data using existing 800 MHz radio system.

Functional Objects

Functional ObjectDescriptionUser Defined
Transit Vehicle On–Board Fare Management'Transit Vehicle On–board Fare Management' supports fare collection using a standard fare card or other non–monetary fare medium and detects payment violations. Collected fare data are made available to the center.False
Transit Vehicle On–Board Information Services'Transit Vehicle On–board Information Services' furnishes en route transit users with real–time travel–related information on–board a transit vehicle. Current information that can be provided to transit users includes transit routes, schedules, transfer options, fares, real–time schedule adherence, current incidents, weather conditions, non–motorized transportation services, and special events are provided. In addition to tailored information for individual transit users, it also supports general annunciation and/or display of general schedule information, imminent arrival information, and other information of general interest to transit users.False
Transit Vehicle On–Board Trip Monitoring'Transit Vehicle On–Board Trip Monitoring' tracks vehicle location, monitors fuel usage, collects operational status (doors opened/closed, running times, etc.) and sends the collected, time stamped data to the Transit Management Center.False
Transit Vehicle Passenger Counting'Transit Vehicle Passenger Counting' collects transit vehicle loading data and makes it available to the center.False
Transit Vehicle Schedule Management'Transit Vehicle Schedule Management' monitors schedule performance and identifies corrective actions when a deviation is detected. It provides two–way communication between the transit vehicle and center, enabling the center to communicate with the vehicle operator and monitor on–board systems.False
Transit Vehicle Security'Transit Vehicle Security' provides security and safety functions on–board the transit vehicle. It includes surveillance and sensor systems that monitor the on–board environment, silent alarms that can be activated by transit user or vehicle operator, operator authentication, and a remote vehicle disable function. The surveillance equipment includes video (e.g. CCTV cameras), audio systems and/or event recorder systems. The sensor equipment includes threat sensors (e.g. chemical agent, toxic industrial chemical, biological, explosives, and radiological sensors) and object detection sensors (e.g. metal detectors).False
Transit Vehicle Signal Priority'Transit Vehicle Signal Priority' provides the capability for transit vehicles to determine eligibility for priority and request signal priority at signalized intersections, ramps, and interchanges through short range communication with traffic control equipment at the roadside.False
Vehicle Basic Safety Communication'Vehicle Basic Safety Communication' exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to calculate vehicle paths, and warns the driver when the potential for an impending collision is detected. If available, map data is used to filter and interpret the relative location and motion of vehicles in the vicinity. Information from on–board sensors (e.g., radars and image processing) are also used, if available, in combination with the V2V communications to detect non–equipped vehicles and corroborate connected vehicle data. Vehicle location and motion broadcasts are also received by the infrastructure and used by the infrastructure to support a wide range of roadside safety and mobility applications. This object represents a broad range of implementations ranging from basic Vehicle Awareness Devices that only broadcast vehicle location and motion and provide no driver warnings to advanced integrated safety systems that may, in addition to warning the driver, provide collision warning information to support automated control functions that can support control intervention.False
Vehicle Control Automation'Vehicle Control Automation' provides lateral and/or longitudinal control of a vehicle to allow 'hands off' and/or 'feet off' driving, automating the steering, accelerator, and brake control functions. It builds on the sensors included in 'Vehicle Safety Monitoring' and 'Vehicle Control Warning' and uses the information about the area surrounding the vehicle to safely control the vehicle. It covers the range of incremental control capabilities from driver assistance systems that take over steering or acceleration/deceleration in limited scenarios with direct monitoring by the driver to full automation where all aspects of driving are automated under all roadway and environmental conditions.False
Vehicle Control Warning'Vehicle Control Warning' monitors areas around the vehicle and provides warnings to a driver so the driver can take action to recover and maintain safe control of the vehicle. It includes lateral warning systems that warn of lane departures and obstacles or vehicles to the sides of the vehicle and longitudinal warning systems that monitor areas in the vehicle path and provide warnings when headways are insufficient or obstacles are detected in front of or behind the vehicle. It includes on–board sensors, including radars and imaging systems, and the driver information system that provides the visual, audible, and/or haptic warnings to the driver.False
Vehicle Intersection Warning'Vehicle Intersection Warning' uses V2V and V2I communications to monitor other connected vehicles at intersections and support the safe movement of the vehicle through the intersection. Driver warnings are provided and the application may also optionally take control of the vehicle to avoid collisions. The application will also notify the infrastructure and other vehicles if it detects an unsafe infringement on the intersection.False
Vehicle Situation Data Monitoring'Vehicle Situation Data Monitoring' is the highest–level representation of the functionality required to collect traffic and environmental situation data by monitoring and storing the experience of the vehicle as it travels through the road network. Collected data is aggregated into snapshots that are reported when communications is available and with flow control based on parameters provided by the infrastructure. Note that this functional object supports collection of data for areas remote from RSEs or other communications infrastructure.False
