This study examines the effects of the permanent traffic increase generated by a private hospital
planned to be opened around the signalized intersection located at the connection of D550
(Çanakkale–İzmir Highway) and Marmara Street in the city center of Çanakkale on intersection
performance. With the hospital becoming operational, it is anticipated that traffic demand at the
intersection will increase due to patient and visitor movements, staff transportation, logistics
services, and ambulance arrivals and departures. The study aims to evaluate the effects of this
increase on performance indicators such as delay, queue length, degree of saturation, level of
service, traffic flow, emissions, and energy consumption. Within the scope of the study, the
open-source microsimulation software SUMO is used. The existing geometry of the
intersection, lane configuration, signalization plan, and traffic demand are determined using
field data; model calibration is carried out with the help of traffic counts, turning movements,
queue lengths, and speed data. Subsequently, four different scenarios are compared: the current
situation, traffic demand after the hospital opening, adaptive signal control, and ambulance
priority. The originality of the study lies in addressing the permanent hospital-induced traffic
demand through a microsimulation approach supported by real field data and evaluating
ambulance priority strategies not only in terms of emergency accessibility but also with respect
to normal traffic flow and environmental impacts. The research is expected to provide decisionmakers
with feasible signalization-based solution proposals instead of high-cost physical
interventions.
