Audio Sample

Most likely it is telemetry for pubic transportation. You can also hear it on 173.275 in Salzburg,there it is confirmed that this comes from the so callen "Obus" which is a electric bus. The buses also can controll traffic lights,but I have to find this frequency. For audio communication the are using 173.075 for communication,and 168.475 Mhz But it would be nice to get the name of the used protocoll.
