Traffic Control System

Traffic Control System

• An efficient and cleaner way to regulate traffic

2

• Aim Of The Project
• To construct a cleaner and more time efficient
  traffic system.
• To minimize the time delays at traffic signals.
• To provide a less dense route to the customers on
  their request.
• To help reduce fuel consumption.
• To help reduce air and sound pollution.

• Parts Of The Project
• A Central Unit that will maintain real time data
  of the traffic density, operate the traffic
  signals and also serve as the other end of Path
  Tracking Unit
• 2) A Communicator Unit installed on every
  vehicle that will give certain information to
  Central Unit
• 3) Traffic signals which are operated
  depending upon the current state of the traffic
• 4) A Path Tracking Unit which shall give the
  customer an available, short and clear route

• The Communicator Unit
• This unit shall contain an antenna, modulator,
  demodulator, speaker, microphone and a processor.
  
• It shall transmit some data to the Central Unit.
  This data shall contain the type, registration
  no. of the vehicle and the speed of the vehicle.
  It is coupled with the speedometer for this
  purpose.
• It shall also have a provision for sending and
  receiving data regarding Path Tracking Unit. (
  This facility is optional)
• In short, this device will be attached to the
  vehicle. The functioning will be on similar
  lines to that of a mobile phone device. On
  commercial scale, the production cost will be
  equivalent to that of low end cell phone

• Collection of Data
• The data sent by the Communicator Units shall be
  collected through Signal Towers of cell phone
  service providers to the Central Unit.
• Techniques
• The position of a vehicle can be tracked down
  using the signal transmitted by the Communicator
  Unit installed in the vehicle. This can Be done
  using the Triangulation Concept. The following
  technique implements this concept
• Uplink Time Difference of Arrival (U-TDOA)

• Central Unit
• This is a vital Unit having the following parts
• Traffic Density Data Analyzer This part
  compares the traffic density along various roads
  accordingly processes the data and feeds it to
  the Traffic Signal Controller. Simultaneously, it
  analysis the data on-demand for path tracking
  system.
• Traffic Signal Controller This determines the
  time durations of the traffic signals and trips
  them accordingly.
• IVRS Setup This contains verbal database of all
  the landmarks, places of a city. The voice input
  of the customer is compared to existing places in
  the database the best route for the customer is
  obtained from the path Tracking Unit is
  provided in terms of the landmarks, names of the
  roads in the path. This is transmitted to the
  customer.
• Path Tracking Unit This unit shall find a short
  less dense route for the customer on his
  demand. The traffic density available routes to
  the customer are compared and a short route is
  decided is sent to IVRS Setup.

• ANALYSIS
• Cost Analysis
• The scaled down version would require the
  development of the Communicator Units, The
  Central Unit, Model of a part of city, some
  minor components.
• Each communicator unit would cost around 1500 Rs.
  On real scale, due to mass production, itll
  become cheaper.
• For central unit, the hardware required would
  correspond to a computer for a modelled version,
  and an IVR system.
• A cardboard model of a part of city with enough
  complexity will be constructed to test the system
  using remote controlled toy cars.
• Models of antenna towers and traffic signal.

• Timeline
• The project shall be done in following sequence
• The Communicator Unit signal transmissions
  (data collection) is dealt first, since they are
  interlinked. We estimate that the Communicator
  Unit will take 2 months for completion.
• The setting up of the Central Unit consists of
  programming , developing database of IVRS. The
  traffic signals will be set up simultaneously.
  The time taken for this will depend upon the
  complexity ( scale) of the system and the
  programming. We estimate that the programming
  of the Central Unit will take 2-3 months.

Necessity of the Project

• So much attention is paid nowadays on traffic
  management.
• Improperly planned roads traffic system.
• Avoiding Traffic Jams.
• Certain features of the Communicator Unit can be
  used for other purposes (Universality).
• Reduction of pollution.
