According to the World Book Encyclopedia, “Throughout most of
history, transportation was extremely difficult. Prehistoric people
travelled mainly on foot. They transported goods on their backs or heads
or by dragging them along the ground. About 5000 B.C, people began to
use animals to haul loads. By 3000 B.C., wagons and sailing vessels had
been invented.” As we try to observe the history of transportation, improvements on vehicle were invented. However,
the increasing population of vehicles affects the traffic condition on
roads. Traffic congestion, traffic jams and traffic accidents occur. On
the contrary, there are possible solutions to prevent or control having
this problems and these include (1)Electronic Signs and Signals (2)
Putting CCTVs (3) Road widening (4) Separate lanes for motorcyles and
huge vehicles(e.g. trucks, buses, cars, jeepneys).


According to Traffic Management Technologies,
- Improved response to incidents by the emergency services. This will greatly contribute to minimizing the likelihood injuries of becoming fatalities at accident sites as the improved response time to providing critical medical care has a proven impact on reducing the likelihood of death from injury.
- Major incidents and congestion are effectively monitored and managed. Rapid and accurate incident detection can provide significant reductions in delays due to incidents. In addition, the chances of secondary incidents or accidents occurring are reduced, providing significant improvements to road safety.
- Rapid overview of network conditions provides up-to-the-minute information for traffic management services and the media. The provision of accurate and timely traffic information is one of the key functions of the traffic management operator. Cameras will allow strategic traffic management from the Traffic Management Centre. This will allow the online updating of signal timings to counter manage unforeseen events or incidents on the arterial network. This includes breakdowns and accidents. This provides a significant contribution not only to road safety, but also to personal safety for stranded motorists."
