Intersection collisions account for a significant portion of accidents and fatalities on roadways. We are developing a vehicle-to-vehicle cooperative collision warning system as part of our effort to enhance driver’s awareness of roadway situation and to reduce the accident rate. Central to the system is a threat assessment algorithm that is based on location and velocity information of the sub...

Distributed Reactive Collision Avoidance Emmett Lalish Chair of the Supervisory Committee: Professor Kristi A. Morgansen Aeronautics and Astronautics Collision avoidance is an important aspect of multivehicle coordination because it prevents vehicles from disrupting or destroying each other. The work contained in this dissertation concerns a novel approach to the n-vehicle collision avoidance p...

Collision-induced migration (CIM) is a process in which energetic gas-phase atoms or molecules at the tail of the Boltzmann distribution enhance surface migration of adsorbates upon collision. It is believed to exist and play an important role in any realistic high pressure-high-temperature heterogeneous catalytic system. Combining supersonic beam-surface collision setup with in-situ optical se...

To analyze the detection probability of shipborne AIS (automatic identification system) signal from space, a mathematical model dependent upon three factors of message collision avoidance, power of signal received by satellite and interference ratio of signal received is presented in the paper. The altitude and footprint area of the AIS satellite are discussed to overcome the collision of messa...

Automotive manufacturers are researching forward collision warning systems (FCWS) to reduce the occurrence of rear-end collision accidents between vehicles. Traditionally these systems use forward scanning sensor technology such as RADAR or LIDAR to measure the distance between the equipped vehicle and other vehicles/obstacles ahead. The U.S. Army is using such technology on their ground vehicl...

For point to point navigation, calculating suitable paths for an an autonomous ground vehicle is computationally difficult. Maneuvering an autonomous vehicle safely around obstacles is essential, and the ability to generate safe paths in a real time environment is crucial for vehicle viability. We previously presented a method for developing feasible paths through complicated environments using...

BACKGROUND Few studies have looked at how obesity affects injury outcomes among vehicle occupants involved in traffic collisions. OBJECTIVE To estimate the association of obesity with death risk among drivers of passenger vehicles aged ≥16 and to examine effect modification by driver sex, driver seat belt use, vehicle type and collision type. METHODS We conducted a matched-pair cohort study...
