Expansion of state

Traffic control system

Due to the Air Pollution Control Act (IG -L), a traffic management system (VBA ) with LED variable message signs in the section Gratkorn North was in 2009 - Lebring built. At too high particulate loads the speed limit is automatically reduced to 100 km / h ( so called particulate hundreds). Also, the driver is warned of fog and dangers. Likewise, LED traffic information boards located at the intersection St. Michael, who warn of construction sites, tunnel barriers or jam. After the closure of the gap S35 S6 offers the route - S35 an alternative to the single-tube and special toll Gleinalmtunnel. With the completion of construction, the new variable direction Styria was around the nodal regions Graz West, Bruck, St. Michael and Peggau - German Feistritzwerke put into operation. This road users can be redirected interregionally signs and electronic billboards and so avoid a traffic jam on your route in the case of distance barriers.

Section Control
