                   Deruytter explained, “The ITS market
                  is a rather traditional market, although
                  traffic authorities have expressed an
                  increasingly greater interest in innovative
                  technologies  over  the  past  decade.
                  For example, many city authorities
                  today are looking into multi-functional
                  technologies, like smart cameras, which
                  are able  to  combine  traffic  detection

                  Prior  to  implementation  of  a  new
                  WIM system, Kistler’s road analysis
                  determines the ideal position for the
                  sensors. This is key since the reliability
                  of measurements and the sensors’
                  lifespan depend on the road quality.
                  This  process  also  helps estimate
                  measurement accuracy. Furthermore,
                  a calibration service from experienced
