DIVERT: A Distributed Vehicular Traffic Re-Routing System for Congestion Avoidance

Abstract

The centralized system encounters two vital issues, the central server needs to perform genuine calculation and communication with the vehicles continuously, which can make such architecture infeasible for extensive zones with various vehicles; and driver security is not guaranteed since the drivers need to share their area furthermore the beginning stages and goal of their excursion with the server, which may keep the acknowledgment of such courses of action. To address these issues, a half and half vehicular rerouting structure is enlivened. The structure off-weights a tremendous part of the rerouting figuring at the vehicles, and therefore, the re-coordinating system gets the opportunity to be useful persistently. To settle on group rerouting decisions, the vehicles exchange messages over vehicular extraordinarily delegated frameworks. The system is hybrid since notwithstanding it uses a server to choose an exact overall point of view of the development more than 2G/3G affiliation. Likewise imperative is that the customer security is balanced with the rerouting ampleness. SCMS issues advanced endorsements to taking an interest vehicles for setting up trust among them, which is imperative for prosperity applications in perspective of vehicle-to vehicle correspondences. It underpins four principal use cases, to be particular, bootstrapping, endorsement provisioning, bad conduct reporting and renouncement. The principle outline goal is to give both security and insurance to the greatest degree sensible and possible. To fulfill the last specified, vehicles are issued pseudonym certificates, and the provisioning of those supports is partitioned among different affiliations. One of the essential challenges is to energize capable renouncement while giving insurance against attacks from insiders.

Towards a distributed and infrastructure-less vehicular traffic management system

“…The assessment of the control channel is important since all the solutions analyzed apply the beaconing approach to share context-awareness information. In the experiments, the beacon transmission rate of 1Hz was set to all systems [4,7], including dEASY. Figure 7 depicts the performance results of the control channel at all the penetration rate possibilities.…”

“…Many works have proposed congestion detection systems and real-time vehicle path planning with the support of VANETs. They also use a combination of different technologies such as induction loops, central server, and road sensors to achieve their goals [4,5,6,7,16,17,18]. The main purpose of these systems is redistributing the flow of vehicle traffic that is going to the congested area, using real-time traffic data collected, to the non-congested area.…”

“…c i indicates the amount of data that contributed to the generation of the new aggregated value. Every time the vehicle receives a report concerning a given road i, it will smooth the computed aggregate average speed v curr agg (i) using the following Equation 7:…”

“…This can be done without the need to invest in new road infrastructure. Due to the limitations mentioned in the first solution, significant research efforts have been directed toward the second one [3,4,5,6,7]. One of the promising technologies for an efficient traffic management system is the Vehicular ad hoc Networks (VANETs).…”

T-Coin: Dynamic Traffic Congestion Pricing System for the Internet of Vehicles in Smart Cities

“…SAINT was applied by Shen et al [24] for an emergency management framework called SAINT+, which used vehicular-to-vehicular communication to decrease the response time of emergency services in case of traffic accidents. Pan et al [25] introduced DIVERT for vehicular networks which is a distributed rerouting and congestion avoidance system. DIVERT uses the vehicles to help the server compute the optimal paths, and therefore the rerouting decisions are possible to perform in real time.…”
