During the heavy rainfall and associated disastrous floods and massive landslides in 2014, the territory of the the Valjevo City, located in the western Serbia, suffered strong road network issues, particularly landslide‐related effects. Herein, it was attempted to assess critical sections, to propose targeted and systematic actions. The network included about 200 km of categorized roads which were identified as elements at risk. The territory was assessed for landslide susceptibility and hazard, by Analytical Hierarchy Process multi‐criteria approach, with standard conditioning factors and landslide inventory from BEWARE project deliverables. Further analysis involved exposure and vulnerability assessment per each road segment, including distance to the highest landslide hazard zone and road segment importance/frequency/quality‐state. These were overlapped and the risk along the road network segments was delineated. High risk points were used to simulate road breaks in various routing impact scenarios, to delineate road segments with highest priority for preventive/precaution actions.
