![]() ![]() Multi-actuators vehicle collision avoidance system - Experimental validation These single vehicle collisions (SVCs), and how to prevent them occurring, are the subject of this report. & Ward, H.Ī third of road deaths in the EU are caused by collisions that involve a single motorised vehicle where the driver, rider and/or passengers are killed but no other road users are involved. ![]() ![]() Reducing deaths in single vehicle collisions.Īdminaite, D. The mean vehicle damage estimate was $1,173. Human injuries were infrequent but potentially serious. The presence of lateral barriers was significantly more frequent at the collision locations. Wild pig- vehicle collisions occurred year-round and throughout the 24-hour daily time period. Annual attrition due to vehicle collisions averaged 0.8 percent of the population. The percentage of males was significantly higher in the single-animal accidents. ![]() As the number of animals per collision increased, the age and body mass of the individuals involved decreased. Most collisions involved single animals however, up to seven animals were involved in individual accidents. The age structure of the animals involved was significantly older than that found in the population. Data included accident parameters pertaining to the animals involved, time, location, and human impacts. In an effort to better characterize these accidents, data were collected from 179 wild pig- vehicle collisions from a location in west central South Carolina. Wild pig (Sus scrofa) collisions with vehicles are known to occur in the United States, but only minimal information describing these accidents has been reported. The developed algorithm has the potential to be used for progressive market penetration of connected vehicles in practice.ĬHARACTERIZATION OF WILD PIG VEHICLE COLLISIONSĮnergy Technology Data Exchange (ETDEWEB) Simulations show its effectiveness on collision mitigation. Model predictive control (MPC framework is used to formulate the problem to be constrained quadratic programming. The impact energy is defined as the relative kinetic energy between a consecutive pair of vehicles (approaching only. The objective is to determine the desired deceleration for each vehicle such that the total impact energy is minimized at each time step. The safety relationship can be represented as lower bound limit on deceleration of the first vehicle and upper bound on maximum deceleration of the last vehicle. The system is defined as a coupled group of vehicles with wireless communication capability and short following distances. This paper proposes a centralized control strategy for multiple vehicles to minimize the impact of multiple-vehicle collision based on vehicle-to-vehicle communication technique. Many previous works focused on collision warning and avoidance strategies of two consecutive vehicles based on onboard sensor detection only. The consequences are even worse for multiple-vehicle collision.
