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
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
