A proposed overtaking model for Egyptian two-lane two-way roads
Overtaking is one of the most complex maneuvers on the two-lane two-way (TLTW) roads, where the follower vehicles use the opposing lane to bypass the leader slower vehicles. Overtaking becomes more riskier with the presence of oncoming vehicles from the opposite direction. This paper presents the de...

| description | Overtaking is one of the most complex maneuvers on the two-lane two-way (TLTW) roads, where the follower vehicles use the opposing lane to bypass the leader slower vehicles. Overtaking becomes more riskier with the presence of oncoming vehicles from the opposite direction. This paper presents the development of an overtaking model for the Egyptian TLTW roads under mixed traffic conditions. About 20-h of videotaped data from 6 different TLTW roads, located in the Delta region in Egypt are studied to develop the proposed model. This model considers key factors affecting model performance that are not considered in most international state-of-the-art models. These factors include (a) acceleration of the follower vehicle (FV) during all phases of overtaking, (b) deceleration of the leader vehicle (LV), (c) length of the LV, and (d) speed change of the LV during overtaking. The proposed overtaking model is divided into two parts. The first part includes two conditions as criteria for acceptance/rejection decision of overtaking while the second part computes the overtaking duration and the corresponding distance for successful overtakes. The model is calibrated for 4 sites and validated on the remaining 2 sites. The results show that the proposed overtaking model matches closely the observed accepted and rejected overtakes by 96.45% and 95.90%, respectively. Furthermore, the results showed that the proposed model was consistent with the observed overtaking distances and times. In addition, the results are compared with other international models such as the Ghods, Tang, TWO-PAS, and Cirianni models. |
