This paper presents an evolutionary algorithm for recognizing high and low crash road segments using Genetic Algorithm as a dynamic segmentation method. Social and economic costs as well as physical and mental injuries make the governments perceiving to road safety indexes in order to diminish the consequences of road accidents. Due to the limitation of budget for safety...

The objective of an accident-mapping algorithm is to snap traffic accidents onto the correct road segments. Assigning accidents onto the correct segments facilitate to robustly carry out some key analyses in accident research including the identification of accident hot-spots, network-level risk mapping and segment-level accident risk modelling. Existing risk mapping algorithms have some severe...

During last decades, owing to the increase in a number of vehicles, the rate of accident occurrence grows significantly. Efforts must be made to provide efficient tools to prioritize segments requiring safety improvement and identify influential factors on accidents. This objective of the research was to determine the safety oriented threshold of International Roughness Index (IRI) to recognize...

This paper describes development and application of a road accident analysis and visualization package Road Accident View (RAV), which integrated Microcomputer Accident Analysis Package (MAAP) and Geographical Information System (GIS) components. GIS offer an advanced engine to drive, both area-wide and location-oriented investigations. With this system the possibility to raise and solve accide...

In this paper a methodology for the development of multiple impact models for road networks is described. Road impacts can be categorized into impacts for different stakeholder groups, namely the public, the owner and the road users. The current investigations address multiple impacts only for road users, but the developed methodology can be extended to estimate the impacts of all stakeholder g...

One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the accident cause makes the selection of high accident prone segments inaccurate. In this paper, by...

road transportation by way of automobiles is a very convenient means of transportation. today, the most detrimental consequence of developing transportation systems in a country is traffic accident that places a huge financial burden on society. this paper investigates the role of information systems in transportation safety that leads to improved planning and operation of the transportation sy...

This paper describes an attempt to shed some light on road safety in Asia Pacific region by characterizing and assessing its road accidents. The relevant national road accident data were extracted from centralized data sources of international agencies. Due to data incompleteness and missing values, 21 Asia Pacific countries, presenting more than half of the world’s population, were selected fo...

spinal cord injuries (sci) are highly disabling and injuries. this study aims to describe the demographic and epidemiologic data on auto accident patients who were admitted at khatam alanbia hospital. the results obtained from 73 sci patients treated on the sci inpatient units of the khatam alanbia hospital (from march 2009 to march 2013) were evaluated retrospectively. then patient gender, age...

road traffic accident (rta) is a global burden of disease. more than 1.25 million people per year are killed by rtas. more than half of the fatalities strike vulnerable road users (e. g. pedestrians, skaters, cyclists and other non-protected road users). the ongoing challenge is to protect vulnerable road users (vru). as a vru is neither shielded by seatbelts or crumple zones nor by airbags, th...
