Implementation of Absolute Priority in a Predictive Traffic Actuation Schemes

Abstract

Nowadays, the improvement of the emergency vehicles' priority is required to improve their response time. Presently, the emergency vehicles alert the road users using the sirens and lights, which might cause disturbances in the traffic or lead to accidents due to the unpredictability of the road users' behaviors. This paper introduces the priority indicator, which calculates the priority of several emergency vehicles as they approach an intersection and sort them in a way that allows granting priority to each one without causing delays neither for the emergency nor for the normal vehicles. The priority indicator is then introduced in a predictive traffic actuation program (DIRECTOR) that adjusts the signal timing in a dynamic way. Thus, this research aims to create a generalized priority form that simplifies granting the priority for emergency vehicles in a harmonized way in all over the Netherlands, making sure that it takes into consideration the several conditions of the intersection.

“…If the infrastructure and the techniques are available, an implementation of an algorithm synchronizing the traffic lights with the use of adaptive traffic control can help for a global optimization approach to achieve a traffic lights configuration that guarantees a sustainable improvement of mobility patterns. (Nesmachnow et al, 2019) The system can be predictive and help allocate the priority depending on the traffic situation and the emergency if the bus is behind schedule, this requires more sophisticated programs and shall be more useful in the future traffic predictive controllers (Boudhrioua and Shatanawi, 2021).…”
