CTA Bus transportation

The Bus Network:

The bus tracker API

The Bus Tracker API allows developers to request and retrieve data directly from BusTime (the system which produces estimated arrival times and which provides location and route information in real-time).

What data is available through the API?

Data available through the API includes:

  •  Vehicle locations
  •  Route data (route lists, stop lists geo-positional route definitions, etc.)
  •  Prediction Data
  •  Service Bulletins

How does the Developer API work?

  • The developer API uses the same data from the BusTime system, which powers CTA Bus Tracker. Information about the location, direction and status of CTA buses is fed from each bus and delivered to the BusTime system, which then can show where buses are or estimate arrival times to stops ahead of a bus.
    Data is updated about once per minute, and arrival estimations are based on how long it normally takes for a bus to get from one place to the next. Because traffic conditions and other unexpected delays occur, we can‖t predict precisely when a bus will arrive—only estimate based on normal travel times during the time of day where an estimate is occurring.
    In order to use the API, the user must sign in to their CTA Bus Tracker account and then request an API key. Only one key will be available per account. Once the request has been approved, the user will be sent an e-mail will be sent to the user containing the API key.

The request that are possible to do with the API technology

  • Delayed Vehicle – The state entered by a vehicle when it has been determined to be stationary for more than a pre-defined time period.
  • Direction – Common direction of travel of a route.
  • Off-route Vehicle – State entered by a transit vehicle when it has strayed from its scheduled
  • Pattern – A unique sequence of geo-positional points (waypoints and stops) that combine to form the path that a transit vehicle will repetitively travel. A route often has more than one possible pattern.
  • Route – One or more set of patterns that together form a single service.
  • Service Bulletin – Text-based announcements affecting a set of one or more services (route,
    stops, etc.).
  • Stop – Location where a transit vehicle can pick-up or drop-off passengers. Predictions are only generated at stops.
  • Waypoint – A geo-positional point in a pattern used to define the travel path of a transit vehicle.

The CTA state:

The Chicago Transit Authority (CTA) operates the nation’s second largest public transportation system–a regional transit system that serves the City of Chicago and 40 neighboring communities. CTA provides 1.64 million rides on an average weekday, accounting for over 80% of all transit trips taken in the six-county Chicago metropolitan region.Presently, CTA service is provided by two modes: bus and rail.Most rides on CTA are taken by bus. Our bus system consists of 140 routes. Buses make over 25,000 trips daily, and serve nearly 12,000 bus stops throughout the region.

Kinect, flexible system for data collection

Information about pedestrian and public transport users activity, including volumes, walking speed, and trajectories, are used by transportation agencies and researchers for planning, design and analysis purposes. There exist a number of technologies for automatic pedestrian data collection; however all have inherent limitations either in functionality or in monetary cost. Also, most technologies only provide counts. The idea we wnat to proposes is the use of an inexpensive motion sensing device: the Microsoft Kinect, which is able to track multiple people in low-light conditions and could be combined with existing video based daytime tracking. The tracking software and speed estimation methodologies are described, and indoor and outdoor studies show the system’s effectiveness at determining pedestrian volumes and walking speeds. The accuracy of speed data is very satisfactory, with correlation of 98% or more with respect to video data validation speeds. The accuracy of pedestrian volume data varies with traffic conditions, however in low to moderate traffic conditions its performance is accept able with an under counting error of about 8%. The different applications of the sensor and its complementarity with other sensors is discussed, this being the first step towards a multi-sensor system.


In this Pdf. is possible to see a very interesting example of the Kinect technology for the control and the analysis of the  customers of one or more shops. The same idea expressed in this document is what we are thinking to applicate in the the bus and railway station of the city

RIFD, GPS for public transport

It is possible to create in some of the neighborhood a transport system based in the technology of the GPS, RIFD, KINECT, smartphones and social network to permit to change the trip of the buses and the position of the bike sharing docks by the preference of the customers?

The idea is to use the smartphones to keep contacted people and public transportations to create the more efficience trip for customers:

The RIFS app for smartphone:

The RFID Connect smartphone app is more than just the conference program guide in the palm of the hand-it’s an interactive tool synched with the RFID Connect Web site, It is possible to search for products, exhibitors and sessions people wish to attend, and add these to your event planner. People can also introduce themself to other attendees and request meetings. Any sessions, meetings or to-dos added to your event planner online will be synched with the smartphone app, and any of these items added on the phone will be reflected on the Web site.

The application can includes the following features:

Passport program: At our larger events, scan a QR Code when you visit a booth and you could win a wide variety of prizes.

Facebook and Twitter: Post to Facebook or Tweet right from the app.

Facility info: View a map of the conference facility.

GPS & Public Transportation article

Have you ever experienced that sinking feeling of knowing you’ve got an appointment to keep and you’ve missed your ride? People who rely on public transport options such as buses have experienced that feeling all too often due to buses not keeping reliable schedules. One day the bus might arrive (and leave) ten minutes early, while the next day it keeps you waiting five to ten minutes longer than expected. Either way, the unpredictable schedule could make you late for work or cause you to miss an important meeting altogether. As cities try to tackle the growing problem, some are turning to GPS vehicle tracking for help.

GPS vehicle tracking allows managers to monitor the movement of fleet vehicles such as city buses from a remote location. A transmitter placed on the vehicle sends signals to a computer, reporting such information as location, speed, duration of stops, and fuel usage. The information gathered enables stricter monitoring of schedules for each individual driver and encourages more precise timing for stops. It also allows location information to be tracked on a website so that transit riders can check to see where the bus is before they head for the bus stop. Sometimes a traffic jam or an accident makes a late stop unavoidable, but with GPS vehicle tracking, passengers will know to plan for the change and can avoid standing in the rain or cold weather while waiting for the bus.

Cities such as Asheville, NC are considering implementing the GPS vehicle tracking technology to improve the overall image of the bus system as well as to better serve their passengers. As more businesses and individuals desire to “go green,” more people may begin taking advantage of public transportation to reduce emissions, a decision which makes reliability an even greater responsibility for city bus systems. People shouldn’t have to make the choice between kindness to the environment and reliable transportation. With the help of GPS vehicle tracking, cities can serve their citizens by giving them the opportunity to take advantage of a reliable transit system that reduces the number of cars on the road.

We’ve all experienced the frustration of being stuck in a traffic jam when you’ve got an appointment to keep. Next time you find yourself stopped in traffic on the way to work, consider whether it might be worth the reduced hassle and reduced emissions to get up a few minutes earlier and catch the bus.
