Traffic congestion has become a major problem in every large city of the world. To ensure a reliable transportation system, it is important to have an intelligent traffic control system. The very first step to do that is to acquire traffic data. Traffic data may come from different sensors. Some examples are use of induction loop, infrared light sensor, optical flow, etc. However, in recent day’s image processing techniques has been very important and promising topic to deal with traffic related problems because of its ease of maintenance and being more intelligent system. Different techniques have been proposed to acquire traffic information. Most of the work detects edge of the vehicles and counts the number of traffic on the road. However the disadvantage of the method is that counting the number of vehicles may give faulty results when the spaces between the vehicles on the roads are very small. Moreover, most of the methods treat only cars as traffic, but in many parts of the world rickshaws, auto rickshaws, bikes are a major part of everyday traffic such as in south Asian countries
Variable message sign and Radar speed signs to ease commuter woes: variable message sign by photon play are the Variable Message Signs are the devices which are used to display the warning signals, messages or information to the people commuting on roads. LED Variable message signs new standards with its LED-based VMS. These signs are efficiently used to warn the people of traffic congestion, speed limits, road work zones, accidents and other incidents. Dynamic Message Signs are the large, electronic signs which overhang or appear along major highways in many Ohio metropolitan areas.
Radar speed signs display unit utilize a radar system that sends out radio frequency waves that bounce off an approaching vehicle to measure its speed. It is displayed on a large, high brightness LED matrix display set up prominently by the roadside to be visible in bright sunlight from a distance. The radar speed limit signs s also displays safe speed limit for that zone. Visualize a driver with his foot down on the accelerator approaching the sign. The flashing LED sign catches his attention and alerts him to the fact that he is exceeding the radar speed limit. The Traffic Calming Signs are used in addition to or in place of speed breakers, speed humps, speed tables, speed bumps and speed cushions. Also known as Driver Feedback Signs, these devices are very successful in managing the traffic on busy roads.
Growth factors of Global Traffic Management: This system is mainly stand for the objective to ensure safety, reduced and trouble-free travel time followed by comfort of effective infrastructure. It is a necessary to monitor the road incidents proactively in order to acquire preventive measures for effective transportation.
- Increased use of advanced technologies.
- huge interest in the population all over the world to own more than one vehicle is increasing the traffics
- On the other hand, growing infrastructures that include the building of huge and smooth national highways are hampering the global market.
- The global traffic management market is one of the factors for growing awareness of the people about traffic rules.
- Speed is important on highway to secure the pedestrian
In addition to improving the compliance of all roadway users with traffic controls and laws, there are several measures that can be taken to improve conditions for pedestrians.
They focus on:
- Slowing vehicle speeds.
- Reducing street crossing distances for pedestrians.
- Improving the visibility of pedestrians.
- Increasing the level of caution taken by pedestrians
- Providing pedestrian facilities (sidewalks, crossing islands)
