Wheel detection and axle counting as key elements of level crossing protection systems
There are approximately 500,000 level crossing protection installations throughout the world. In many respects, new construction, expansion, optimisation and on-going renewal offer potential for innovation and further technological development within this market segment of railway signalling technology (Fig. 1). The range of types and variants of technical designs for level crossing protection systems is extremely widespread. The main reasons for this are country-specific design and safety requirements as well as approval regulations. In addition, providers of level crossing protection systems who generally operate on a local or regional basis work to different standards and offer various technical solutions.
