“…DOT and will form the central focus for its IntelliDrive program, formerly known as vehicle-infrastructure integration.2. The analysis illustrates that DSRC is the only viable technology in the near term that offers the latency, accuracy, and reliability needed for active safety.The preceding critical points have motivated a lot of interest in developing applications with DSRC technology to improve safety and mobility of traffic on U.S. highways (3)(4)(5)(6)(7)(8)(9)(10)(11). Recently, a remote collision avoidance system using DSRC-based V2V communication was verified (8).…”

This paper describes the architecture, functionality, and field demonstration of a newly developed dedicated short-range communication (DSRC)–based vehicle-to-infrastructure communication system for improving traffic efficiency and safety in work-zone-related congestion buildup on U.S. roadways. The goal was to develop a portable system that could be easily deployed at a work-zone site to acquire and communicate important travel information, such as the start of congestion (SoC) and travel time (TT) of the driver. With this information, drivers could make informed decisions about route choice and be prepared for upcoming congestion. The system is composed of a portable roadside unit, which can engage the onboard units (OBUs) of traveling vehicles with DSRC technology to acquire necessary traffic data (speed, time, and location). With the acquired data, the roadside unit periodically estimates the SoC and the TT, which are broadcast to all vehicles in the coverage range. An OBU receiving the broadcast message calculates the distance to the SoC. The distance to the SoC and the TT are then relayed to the driver, who can make smart decisions about whether to seek an alternate route and when to expect a sudden speed reduction. Results from the field demonstration have shown that the developed system can adapt to a changing work-zone environment smoothly under various congestion patterns on the road.

Cooperative Intersection Collision Avoidance System (CICAS) program uses roadside radar sensors, a computer processor and algorithms to determine unsafe conditions, and an active LED icon based sign to provide timely alerts and warnings which are designed to reduce the frequency of crashes at rural expressway intersections. The cooperative component of the CICAS system consists of roadside equipment (RSE), on-board equipment (OBE), geospatial information database (GID) and intersection sign state (ISS). Both the RSE and OBE use dedicated short range communication (DSRC) radios operating on the 5.9GHz band. For the tests described in this paper, the supplier of the DSRC radios is Arada. The tests documenting performance were done at the CICAS test intersection located at the intersection of U.S. 169 and County State Aid Highway 13 north of Milaca, MN. The goal of this test was to determine the efficacy with which information can be broadcast from the RSE and received by the OBE as a function of direction and distance of travel from the intersection. The result is it is sufficient to ensure that approaching vehicles will receive a complete GID in sufficient time for its intended use.

This paper describes the architecture, functionality, and field demonstration results of a newly developed dedicated short-range communication–based vehicle-to-infrastructure work zone traffic information system with vehicle-to-vehicle assistance. The new system is portable and can automatically acquire important work zone travel information such as the travel time and the starting location of congestion and then relay this information to drivers approaching the congestion site. Such information can help drivers make informed decisions on route choice, prepare for upcoming congestion, or both. The authors had designed a similar system earlier; that system had limited congestion coverage and message broadcast ranges, but the new system can achieve a much longer broadcast range (up to a few tens of kilometers) and can handle much longer congestion coverage (up to a few kilometers) by incorporating vehicle-to-infrastructure communication assisted by vehicle-to-vehicle communication. The system requires only a single roadside unit to acquire traffic data by engaging the vehicles traveling on the road whether within or outside of its direct wireless access range. From the traffic data, the system estimates important traffic parameters such as travel time and starting location of congestion and periodically broadcasts this information back to the vehicles approaching the congestion well before they enter the congested area. The results from the field demonstration show that the new system can adapt to a dynamically changing work zone traffic environment and can handle much longer congestion lengths as compared with the previous system, which used only vehicle-to-infrastructure communication without vehicle-to-vehicle assistance.
