Abstract

With the advancements in technology, the concept of transforming urban landscapes into sustainable and efficient environments is gaining more and more interest worldwide, thanks to the integration of new communication systems and intelligent devices. This concept is known as Smart Cities. An important aspect for it is then Traffic Management, in which a key point to improve in order to achieve the Smart City goals is Intersection Management. By implementing Internet of Things solutions, like an auction system in the semaphore controllers aided by a central server to propagate the vehicles' bids, we can reduce the average waiting times at traffic lights, and thus the overall trip times. For such a system to be applied in reality it might need to support many different layouts, including roads divided in multiple lanes and with restricted turns; yet, many approaches in the literature do not consider this established solution, used to improve intersections since decades ago. Because of this reason, we propose mitigations for this problem: we take such an auction-based semaphore approach and implement support for lanes. We test our solution on a grid network using the renowned transport simulator MATSim, comparing it against the previous results it achieved, along with other related auction systems: one with a different propagation scheme for bids and one with no coordination, using a Fixed Time Control as a baseline. By studying the results, we demonstrate that it is indeed worthwhile to include such a fundamental staple of traffic management into the evaluation of new solutions, as they apply to many locations all around the world.

Conflict-free Intersection Management through Auctions of Vehicles in a Smart City grid
With the advancements in technology, the concept of transforming urban landscapes into sustainable and efficient environments is gaining more and more interest worldwide, thanks to the integration of new communication systems and intelligent devices. This concept is known as Smart Cities. An important aspect for it is then Traffic Management, in which a key point to improve in order to achieve the Smart City goals is Intersection Management. By implementing Internet of Things solutions, like an auction system in the semaphore controllers aided by a central server to propagate the vehicles' bids, we can reduce the average waiting times at traffic lights, and thus the overall trip times. For such a system to be applied in reality it might need to support many different layouts, including roads divided in multiple lanes and with restricted turns; yet, many approaches in the literature do not consider this established solution, used to improve intersections since decades ago. Because of this reason, we propose mitigations for this problem: we take such an auction-based semaphore approach and implement support for lanes. We test our solution on a grid network using the renowned transport simulator MATSim, comparing it against the previous results it achieved, along with other related auction systems: one with a different propagation scheme for bids and one with no coordination, using a Fixed Time Control as a baseline. By studying the results, we demonstrate that it is indeed worthwhile to include such a fundamental staple of traffic management into the evaluation of new solutions, as they apply to many locations all around the world.
