Abstract
Theoretically there is a fundamental relationship between the number of accidents, speed and volume. Mathematical and graphic relationships can be used to understand those traffic behaviour. This model is expected to provide estimates or predictions of traffic accident figures as a basis to improve traffic safety on Surabaya-Gempol toll road. Data processing is performed using the non-linear Poisson regression method because accident rates are discrete and cannot be negative. From the results it is known that in Waru-Sidoarjo segment, the lower the speed, the denser the traffic volume and accidents will remain constant. In the Sidoarjo-Porong section, the denser the traffic volume, the speed will decrease and the accident rate will increase. In Kejapanan-Gempol section, the denser the traffic volume, the less accidents will occur.
