In train collisions, multi-level rail passenger vehicles can deform in modes that are different from the behavior of single level cars. The deformation in single level cars usually occurs at the front end during a collision. In one particular incident, a cab car buckled laterally near the back end of the car. The buckling of the car caused both lateral and vertical accelerations, which led to u...

The objective of this paper is to optimize defrost/demist performance in a vehicle. However, to initiate the problem, it is necessary to have a thorough understanding of flow behavior within the compartment. So a full-scale model of passenger compartment has been modeled and the air stream from very near to the windshield up to back of the compartment has been analyzed applying computational fl...

We undertook a study to determine if the automatic detection and counting of vehicle passengers is feasible. An automated passenger counting system would greatly facilitate the operation of freeway lanes reserved for car-pools (HOV lanes). In the present paper we report our findings regarding the appropriate sensor phenomenology and arrangement for the task. We propose a novel system based on f...

SUMMARY This paper presents an extension of Lighthill, Whitham and Richards' dynamic traffic flow model (LWR) to a number of vehicle classes. Each class will be described by a separate fundamental diagram. When the various diagrams are similar in shape a scaling can be carried out that is related to the passenger-car equivalents. We present both an analytical framework and a numerical computati...

background: motor vehicle crashes (mvc) are considered to be the most common safety challenge, causing more than a million deaths worldwide annually. objectives: the current study was aimed at identifying the etiological role of human and vehicle safety factors in road crashes, and their effects on the severity of injury and fatality in the sistan and baluchistan province, south east iran. pati...

To evaluate the performance and scalability of Altair RADIOSS on Intel® Xeon® processor E7-4890 v2, Altair benchmarked RADIOSS using a modified publicly available crash simulation model of a Chrysler Neon* passenger car on a single-node platform with 4 sockets/60 cores/120 threads and 256 GB of memory. RADIOSS was able to easily take advantage of all 60 cores, running the workload 2.75X faster ...
