Why CAMEA Combines WIM with Other Technologies for Direct Enforcement
As part of a Proof-of-Concept project, CAMEA has successfully installed, tested, certified and handed over a CAMEA ITS system in Oman that weighs vehicles in motion (WIM) and also measures their speed. By combining the two functions into one system, the system's utility value is significantly increased as individual components are shared for multiple functions.
With respect to saving both investment and operating costs, it is very efficient to use sensors, cameras, computing units, power and communication infrastructure for two enforcement systems certified for fully automated direct enforcement at the same time. In practice, trucks, which by definition drive relatively slowly, are often overloaded, and passenger cars, which are typically not overloaded, often exceed the speed limit.
Proven Effectiveness and Traffic Observations
The effectiveness of such a solution was demonstrated by analyzing the measured data, where some vehicles were found to weigh around 120 t, many of them repeatedly. These were mostly tank trucks going to a nearby refinery and vehicles carrying earth, which are frequently transported commodities in Oman. In addition, several vehicles per day were found to pass through the WIM station at speeds of over 200 km/h.
It is now up to the user to decide how to deal with the offenders, but it is already evident that CAMEA ITS technology can make a significant contribution to road protection and road safety in Oman, without the need to install two enforcement systems. CAMEA is deploying a similar concept in other countries around the world
