Traffic management systems are mostly based on the data supplied by local detectors. Frequently, these site-based measuring values must then be processed further to provide road-specific information. This is done using estimation procedures and models which in some cases do not sufficiently reflect reality.
Direct Data Collection
New approaches involve the direct collection of road-specific data such as travel time and speed. Traffic jams and disruptions can be derived from this data with much more accuracy.
Siemens offers two sustained, infrastructure-supported solutions: Sicore and Wimag. Two high-tech solutions, many advantages:
Direct and precise measurement of travel time
Determination of traffic volume
High technological reliability
Easy to install
The Sicore Camera
... automatically recognizes any number plate and has undergone extensive field testing. Almost every vehicle is recognized, classified and then, at a second monitoring station, positively identified.
Sicore is suitable for measuring the travel time, also for long road sections with a high number of turn off and entry processes. The high recognition rate allows the travel times to be measured with a high accuracy.
The Wimag Detector
… a “wireless magnetic detector”. It stands for innovation with added value:
Low installation costs
Fast and simple installation in the road surface
Practical readings of only 7,5 x 7,5 x 5,0 cm
No supply cables necessary
Long life span of about ten years
Wimag measures the magnetic signatures which vary from vehicle to vehicle. The data obtained is transmitted by radio to a base station and evaluated there. Due to the achieved recognition rates, the detector can also be used for travel time measurement. This detector is suitable for sections with a length of one to three kilometers and for a small or medium number of turn off and entry processes on the road.
