Objectives

• To install the incident detection system for
  monitoring congestion and route diversion on
  National Highways / major urban arteries and
  evaluate the efficacy of different technologies
  of various incident detection systems under
  mixed mode traffic.

Steps involved
Video cameras are installed at the site to
receive the traffic data and transformed to
Ethernet by the 2 m.b modem line. Ethernet
receives and transforms the data to matrix
unit. This matrix unit converts the data into
analog and digital mode and sends the digital
mode to CCTV to observe the live data Digital
mode data is send to analyzer which will indicate
the occurrences of the incidents and collect the
data.

Video Processing Principles

• Check the validity of the alarm
• Assess the importance of its consequences
• Precisely locate the incident and its scale
• Define appropriate actions

Functions of the Video AID

• 1. Recording of video sequences showing the
  different phases of an accident from its causes
  to its consequences.
• 2. Alarm functions
• 3. Measure functions
• Vehicle stopped on traffic lane in fluid traffic
  conditions
• Vehicle stopped on traffic lane in congested
  traffic conditions
• General slow down on traffic lanes
• Slow moving vehicle
• Fast moving vehicle
• Wrong way vehicle incidents
• Overall traffic speed,
• Flow rate
• Occupancy rate
• Average travel time in the image
• Queue length
• Head way

Application of Citilog Software

• it is necessary to set up and configure each
  camera for the following parameters
• Starting media configuration
• Connection to a camera and the associated
  analyser
• Loading or creating a configuration
• Changing a configuration
• Saving the configuration
• Sending the configuration to the corresponding
  analyser

Inferences about VIDS

• It is interesting to observe from the figures
  that the plot between observed data and system
  data are reasonably close to each other, thereby
  signifying the reliability of the system.
• Volume count obtained using the CITILOG software
  is almost matching with the ground counts but
  always showing lesser values.

31
Inferences (Contd)

• age error in traffic volume is more during peak
  hours as compared to non peak hours. This may be
  due to extreme congestion and non adherence of
  lane discipline.
• Thus it can be concluded that CITILOG software
  can be used in Indian traffic conditions for the
  purpose of traffic flow analysis and incident
  detection, if the traffic moves adhering lane
  discipline.

Background
GDP growth estimate to 9.0 2006. ( Source
Financial times, January 31, 2007)
Transport infrastructure in major constraint on
accelerated growth. Urban areas Travel demand is
increasing in many folds, having limited
resources to expand the network
further. Increases in negative externalities
with increase in travel demand Other alternative
advancement ITS Solutions, which successfully
demonstrated in developed countries.

Status of Road Transport in India Need for the
ITS
Applying Spatial Data for Advanced Traffic
Management Using ITS
Tremendous diversity in all aspects of Economy
Per capita income, Family income levels
etc. Road development 3.3 millions Kms( NH, SH,
MDR Village roads and Ordinary roads) NH
accounts 2 of total network carrying 40 total
traffic, All modes should compete for the same
lane. Fatalities per annum (2004) more than
1,00,000 accounts 10 world road fatalities ( NH
accounts 20 total fatalities.). Accidents ,
fatalities and causalities increased
dramatically, about 5 growth rate in last two
decades. Death rate per vehicle is 10 to 20 time
higher in India as compared to high developed
countries ( USA, UK, Sweden, Norway, Japan,
Australia,etc.,). Much higher even compared to
developing countries ( Brazil, Mexico, Malaysia
etc)
Intelligent Transport Systems is the one of the
best way to increase the efficiency of the
existing network, and increase the safety.
