PENENTUAN RUTE EVAKUASI PENANGANAN KORBAN KECELAKAAN LALU LINTAS DI LOKASI RAWAN KECELAKAAN (STUDI KASUS : KOTA YOGYAKARTA)

Yogyakarta City is one of the cities with a relatively high number of accidents. Accidents that tend to occur during peak hours certainly impact the delay in carrying out evacuations for accident victims, even when using ambulances, which are priority vehicles on the road. This problem is exacerbated if there are no effective route indicators to expedite access to adequate healthcare facilities, such as hospitals. Out of a total of 18 blacklink in Yogyakarta City in 2023, 5 blacklink have recorded accident victims who died while en route to healthcare facilities, specifically hospitals. Therefore, the researcher developed evacuation routes for handling traffic accident victims in accident-prone areas. Route determination involved first identifying the service areas of healthcare facilities (hospitals) and then determining the evacuation routes using Dijkstra's Algorithm. The variables used in route determination include the travel time of each segment directly connecting blacklink with hospitals. The analysis shows that most areas of Yogyakarta City are covered and fall within the service area of hospitals. The route determination resulted in 29 evacuation routes, both from referral hospitals to blacklink and vice versa. These routes have a travel time of less than 5 minutes, so when considering the 10-minute response time, these routes are expected to facilitate victim evacuation and reduce the potential increase in fatality rates among accident victims.
