Special Issue Information

Dear Colleagues,

Traffic accidents caused by automobiles and environmental problems are common in today’s world. Consequently, various efforts are being made to realize improved road safety, including the construction of more advanced road transportation infrastructure and the utilization of research. For environmental issues, the realization of carbon neutrality is crucial. There are also concerns about the shortage of drivers for public buses and logistics trucks due to the declining birthrate, aging population, and shrinking workforce. The evolution of society toward sustainable mobility is expected to solve these issues. Intelligent Transport Systems (ITSs) represent systems that use state-of-the-art information and control technologies to prevent accidents, traffic congestion, and environmental issues. ITSs also require a joint effort by the public and private sectors, including the development of official standards and laws set by the government, the deployment of transportation infrastructure in cooperation with related ministries, and the proposal and reflection of such standards in future policies. The current automotive industry is said to be in the midst of a period of change, with ongoing R&D and demonstrations of connectedness, automation, sharing, and electrification.

This Special Issue aims to publish original and visionary papers describing scientific methods and technologies that can improve the efficiency, productivity, quality, and reliability of transportation systems. In this Special Issue, we will focus on the efforts toward making efficient, human- and environmentally-friendly, and sustainable intelligent transportation systems a reality. We strongly encourage contributions detailing scientific results from experts from academia and industry around the world.

Convoys composed of autonomous vehicles could improve the transportation and freight industries in several ways. One of the avenues of improvement is in fuel efficiency, where the vehicles maintain a close following distance to each other in order to reduce air resistance by way of the draft effect. While close following distances improve fuel efficiency, they also reduce both the margin of safety and the system’s tolerance to disturbances in relative position. The system’s tolerance to disturbances is known as string stability, where the error magnitude either grows or decays as it propagates rearward through the convoy. One of the major factors in a system’s string stability is its delay in sending state updates to other vehicles, the most pertinent being a hard braking maneuver. Both external sensors and vehicle-to-vehicle communication standards have relatively long delays between peer vehicle state changes and the information being actionable by the ego vehicle. The system presented here, called the Convoy Vehicular Ad Hoc Network (Convoy VANET), was designed to reliably propagate emergency event messages with low delay while maintaining reasonable channel efficiency. It accomplishes this using a combination of several techniques, notably relative position-based retransmission delays. Our results using Network Simulator 3 (ns3) show the system propagating messages down a 20-vehicle convoy in less than 100 ms even with more than a 35% message loss between vehicles that are not immediately adjacent. These simulation results show the potential for this kind of system in situations where emergency information must be disseminated quickly in low-reliability wireless environments. Full article

Cooperative intelligent transport systems (C-ITS) continue to be developed to enhance transportation safety and sustainability. However, the communication of vehicle-to-everything (V2X) systems is inherently open, leading to vulnerabilities that attackers can exploit. This represents a threat to all road users, as security failures can lead to privacy violations or even fatalities. Moreover, a high fatality rate is correlated with soft-mobility road users. Therefore, when developing C-ITS systems, it is important to broaden the focus beyond connected vehicles to include soft-mobility users and legacy vehicles. This work presents a new approach developed in the context of emerging hybrid networks, combining intelligent transport systems operating in 5.9 GHz (ITS-G5) and radio-mobile cellular technologies. Two protocols were implemented and evaluated to introduce security guarantees (such as privacy and integrity) in communications within the developed C-ITS hybrid environment. As a result, this work securely integrates G5-connected ITS stations and soft-mobility users through a smartphone application via cellular networks. Commercial equipment was used for this goal, including on-board and roadside units. Computational, transmission and end-to-end latency were used to assess the system’s performance. Implemented protocols introduce an additional 11% end-to-end latency in hybrid communications. Moreover, workflows employing hybrid communications impose, on average, an extra 28.29 ms of end-to-end latency. The proposal shows promise, as it reaches end-to-end times below the latency requirements imposed in most C-ITS use cases. Full article
