Extensible database systems allow users to create new data types representing spatial, text, image, and other multimedia objects, and functions which operate on the new types[S96]. The new data types and functions can be used as predicates in SQL queries. Consider an insurance industry application, built using an extensible DBMS that has user defined extensions for spatial, text, date/time, and...

Traditional actuarial pricing procedures have focused on pre-accident driver attributes, vehicle characteristics, and garaging location in an effort to explain personal automobile loss cost “drivers.” Although these traditional factors are important for statewide ratemaking in a static environment, they account for only part of the influences on auto insurance loss costs. This paper draws on th...

The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...

OBJECTIVES To determine the prevalence rate of post traumatic stress disorder (PTSD) and associated risk factors among motor vehicle accident (MVA) survivors attending the orthopaedic and trauma clinic at Kenyatta National Hospital, Nairobi. DESIGN A cross-sectional study. SETTING Kenyatta National Hospital, Nairobi. SUBJECTS One hundred and ninety seven adult males and sixty seven female...

This paper summarizes the results of an effort to identify and rank vehicle collision scenarios in order to create a "collision typology" that could aid in the assessment of the potential benefit of accident avoidance technologies. Data from four computerized accident files were used to construct an 18-level collision configuration variable. This variable includes the number of vehicles involve...

Accidents statistics show that multiple-event accidents (MEAs) represent a considerable and increasing proportion of all vehicle traffic accidents. MEAs are characterized by having at least one vehicle subjected to more than one harmful event. MEAs now comprise approximately 25% of all passenger vehicle accidents. This thesis aims to make systematic progress towards developing a vehicle Post Im...

This paper proposed an intelligent RFID traffic cone that is applied for vehicle accident detection and identification based on image compressing analysis and RFID detection tracking in an accident clamming system and traffic reporting system. The gain benefit of this paper can reduce the waiting time of an accident clamming process that usually used along time with normally vehicle crash acces...

Pavement frictional characteristics are commonly determined by conducting skid tests in accordance with ASTM Standard E274. The results of these tests [skid number (SN)] are used in ranking roads to establish construction priorities and to estimate tirepavement friction in accident analysis. The role of SN in these two applications is addressed. There are serious limitations constraining the us...

The problem of generating a 3D simulation of a car accident from a written description can be divided into two subtasks: the linguistic analysis and the virtual scene generation. As a means of communication between these two system parts, we designed a template formalism to represent a written accident report. The CarSim system processes formal descriptions of accidents and creates correspondin...

Vehicular ad hoc networks (VANETs) have been a research focus in recent years. VANET’s applications are mostly applied to the road safety and reduce the traffic accident earlier. Moreover, use VANET system can also help the emergency vehicles go to accident location as soon as possible. Therefore how to protect the transmission message is important. We propose a secure emergency vehicle transmi...
