“…DSRC is commercially available but highly expensive [16]. To counter the high-cost of commercial devices, we previously designed a laptop-based testbed [17] and an SDR-based testbed [10], with the latter being utilized for the simulations in this paper.…”

“…This section will be used to briefly introduce our testbed, experiment methodology, and the field tests conducted to gather our results. This testbed is based on our previous works relating to an empirical DSRC testbed utilizing SDR devices [10], and we conducted empirical evaluations as to the capabilities of the system. Further details on the testbed can be found in this work.…”

“…We believe analyzing the reliability and the impacts of consecutive loss are vital for identifying safety-related performance aspects. The testbed used in this work has been previously demonstrated in Reference [10] and shown to perform to DSRC standards. This work investigates how stopping distance can be reduced, as well as the impact of consecutive packet loss or burst losses on stopping distance.…”

“…The novelty of this paper is in two key areas, the first being an extension of previous work [10] where we will be investigating and modeling the reduction of stopping distance that can be achieved with vehicle communications. In the second, we will be modeling the impact of consecutive packet losses and how this alters the reduction we have shown is attainable with communication, and a model has been designed to allow this to be proven.…”

Dedicated Short-Range Communication (DSRC) or IEEE 802.11p/OCB (Out of the Context of a Base-station) is widely considered to be a primary technology for Vehicle-to-Vehicle (V2V) communication, and it is aimed toward increasing the safety of users on the road by sharing information between one another. The requirements of DSRC are to maintain real-time communication with low latency and high reliability. In this paper, we investigate how communication can be used to improve stopping distance performance based on fieldwork results. In addition, we assess the impacts of reduced reliability, in terms of distance independent, distance dependent and density-based consecutive packet losses. A model is developed based on empirical measurements results depending on distance, data rate, and traveling speed. With this model, it is shown that cooperative V2V communications can effectively reduce reaction time and increase safety stop distance, and highlight the importance of high reliability. The obtained results can be further used for the design of cooperative V2V-based driving and safety applications.

The limited connectivity of vehicles presents a notable challenge, as their inability to establish communication with other vehicles and pedestrians can lead to safety concerns, particularly for vulnerable road users (VRUs). The Infrastructure-to-Pedestrian (I2P) communication pathway can play a vital role in mitigating these safety concerns, as implementing I2P is expected to significantly enhance safety for pedestrians, cyclists, and motorcyclists. The Third Generation Partnership Program (3GPP) introduced cellular vehicle-to-everything (V2X) communication with the release for 3GPP Release 14 in 2017. In this paper, we conduct an extensive review of V2I and I2P communication, and then present a Long-Term Evolution (LTE)-I2P communication architecture. We later describe key ideas of software-defined networks and their concepts for I2P services. Additionally, we conduct a field test of I2P LTE-based communication and assess its feasibility. The urban connected testbed in downtown Chattanooga, “MLK Smart Corridor,” services is the experimental platform for this assessment. Performance indicators like average end-to-end (E2E) latency and packet delivery ratio (PDR) are used for comparison.
