APTS Technologies

The Florida APTS website provides a comprehensive guide to various Advanced Public Transportation Systems (APTS) technologies. This guide provides a short description of each technology type with pictures if available. Select from the technology types on the left menu to view the information.

Automatic Passenger Counters
Automatic Passenger Counters (APCs) are devices that automatically count the number of passengers as they board and alight buses at each stop during a trip. An on-board microcomputer is the central processing unit of an APC system. It analyzes the signals received from the sensors in real time, then creates an electronic record at each bus stop and stores the results in memory. Data stored typically include the following: vehicle location (usually latitude and longitude coordinates), date and time the bus stops, times the doors open and close, number of passengers boarding, and number of passengers alighting. Often, additional information is recorded by time and location, such as the deployment of wheelchair lifts and bike rack utilization. These records are grouped by trip and are also stored on the vehicle until they are downloaded to an internal computer at the transit property for further processing .


Automatic Vehicle Location
Automatic Vehicle Location (AVL) systems are computer-based vehicle tracking systems that function by measuring the real-time position of each vehicle and relaying this information back to a central location. AVL systems are most frequently used for fleet management to identify the location of vehicles for a variety of purposes including: improved dispatch, operation efficiency, and faster response times to disruptions in service.


Fare Collection Systems
The collection, processing, and safekeeping of passenger fare revenues and ridership data are essential and important to a public transit system. The development of new farebox systems and advancements in support technology and software systems has provided the transit industry with a number of increased efficiencies in fare revenue and passenger recording structures .


Traveler Information Systems
Traveler Information Systems combine computer and communications technologies to provide information to travelers at home, at work, on the roadside, at bus and rail transit stations, or on the vehicle. This enables transit providers to supplement printed route maps, schedules, and fare information with dynamic real-time information about route delays, arrival estimates, next stop and transfer possibilities. Travelers can access real-time schedules and congestion information through telephones, cable television, personal computers, cellular phones, pagers, hand held computers, variable message signs, or kiosks. Implementation will be a major opportunity and challenge as applications of real-time information systems become more widely distributed
