Electronic toll collection system (ETCS) devices on vehicles communicate wirelessly with road head devices at toll stations. ETCS is preferred in countries because it is more convenient and efficient than manual toll collection. However, the scattered and constant innovations in this sector require a bridge between worldwide ETCS usage and advancements and a single page to grasp this sector's developments to ensure further developments. Following a systematic review, this study examined ETCS worldwide and technology adaption considering the scopes, limitations, usages, and related technology of the ever‐developing electronic toll collection system. Existing ETCS technologies have been investigated and synchronized with ingrowing tech disparity to overcome the research synchronization gap. The study also included a bibliometric assessment to identify the important areas of research, technologies most used, degree of knowledge generated, growth/trend of the researches, most well‐known authors, keywords, countries, documents, source of publication, and so on considering time‐to‐time changes. The study provided bibliometric solutions to the gap of lack of synchronization of research worldwide and even ETCS implementation difference within a country, which complicated collaboration with the central system and linked organizations and made it difficult for users to adapt the system.

“…However, vehicular communication protocols like IEEE 802.11p [36] aim to make the new standard more robust in the real-world vehicular scenarios [40]. For example, in IEEE 802.11p, the vehicles are allowed to transmit and receive data frames with the wildcard setting, which means the vehicles can immediately communicate with the RSU upon encounter without any additional overhead [40], [41]. Consequently, since we focus on the distribution of contact, we only investigate the potential communication opportunities between vehicles and RSUs, and we leave the issues related to how to ensure successful data transmissions during contacts as future work.…”

Roadside units (RSUs), which enable vehicles-toinfrastructure communications, are deployed along roadsides to handle the ever-growing communication demands caused by explosive increase of vehicular traffics. How to efficiently utilize them to enhance the vehicular delay tolerant network (VDTN) performance are the important problems in designing RSU-aided VDTNs. In this work, we implement an extensive experiment involving tens of thousands of operational vehicles in Beijing city. Based on this newly collected Beijing trace and the existing Shanghai trace, we obtain some invariant properties for communication contacts of large scale RSU-aided VDTNs. Specifically, we find that the contact time between RSUs and vehicles obeys an exponential distribution, while the contact rate between them follows a Poisson distribution. According to these observations, we investigate the problem of communication contact-aware mobile data replication for RSU-aided VDTNs by considering the mobile data dissemination system that transmits data from the Internet to vehicles via RSUs through opportunistic communications. In particular, we formulate the communication contact-aware RSU-aided vehicular mobile data dissemination problem as an optimization problem with realistic VDTN settings, and we provide an efficient heuristic solution for this NP-hard problem. By carrying out extensive simulation using realistic vehicular traces, we demonstrate the effectiveness of our proposed heuristic contact-aware data replication scheme, in comparison with the optimal solution and other existing schemes. , IEEE Transactions on Mobile Computingwithχ(t k ) = χ r − χ u (t k ) . Consequently, the contact duration can be obtained by t d − t c . Then, the contact interval can be obtained as the time interval of two successive communication contacts. We note that the LI method is based on the approximate assumption that the distance between RSU and vehicle changes linearly closed to and during the communication 1536-1233 (c)

“…The second car may stop without collision when the first car brakes hard, based on driver vision, but the third car cannot stop fast enough and collides with the second car. If the cars had vehicle-tovehicle communication devices, such as ITRI WAVE/ DSRC Communications Units (IWCUs) [8], each car could broadcast basic safety message (BSM) [9] information to warn cars in the neighbourhood. Hence, the third car would receive the broadcast BSM information from the first car; and based on this information, the third car would decide whether to alert the driver.…”

Safety applications in vehicular networks have been popular research topics in recent years, such as forward collision warning, emergency braking warning and intersection collision warning systems. The basic safety message broadcast from each car transmits the position, car speed and car heading information. Neighbouring cars receiving this information can decide if there is any danger within the next second. However, the safety application message has positioning accuracy and time-critical problems. Accurate positioning of the car provides a more effective warning to the driver. Moreover, the reliable and efficient delivery of safety information needs to be improved when the penetration rate increases. Hence, this paper proposes a cooperative emergency braking warning system to solve the above problems. This is a system that integrates a camera sensor to construct the state of neighbourhood cars in order to solve the first problem. It then proposes to reduce the repeat and derivable information between the broadcast messages in order to solve the second problem. The proposed system has been implemented to provide a safer driving environment.
