14. TRANSPORTING CHILDREN IN CARS AND THE USE OF CHILD SAFETY RESTRAINT SYSTEMS
ABSTRACT Objective: To evaluate the transport of children in automobiles and the use of child restraints systems (CRS). Methods: This is a transversal descriptive study which included 200 vehicle drivers who carried 0-10 year old children in the city of São Luis, MA, Brazil. The drivers' passengers' and children's features were properly identified. The ch

15. Effect of driver's personal characteristics on traffic accidents in Tabuk city in Saudi Arabia
AbstractTraffic accidents are a major problem in developing countries. Saudi Arabia is no exception to this worldwide dilemma. In Saudi Arabia a high incidence of road accidents has been recorded in the last several years due to various factors. The aim of this paper is to examine what factors contribute to road accidents in the study area; and to evaluate s

16. Numerical Analysis of an Intercity Bus Structure: A Simple Unifilar Model Proposal to Assess Frontal and Semifrontal Crash Scenarios
Abstract To improve the safety of the intercity bus structure against impact scenarios and to reduce the injuries and death in traffic accidents it is crucial in a country with continental dimensions like Brazil, where the road transport matrix is fundamental in the traffic of people and goods. In this context in the present article, a numerical model of an

17. Bridging a historical gap: can changes in perceptions of law enforcement and social deterrence accelerate the prevention of drunk driving in low and middle-income countries?
Objectives: The dangers of driving while under the influence of alcohol/drugs (DWI) have been well established. Many countries have successfully reduced the incidence of DWI through effective law enforcement. We aim to explore the links between how law enforcement is perceived in cultures with different socioeconomic indicators. Our hypothesis is that socia

18. Comparison between common traffic lights and three types of traffic lights with visual cycle – a safety and capacity analysis
Abstract The objective of this paper is compare the common traffic lights (CTL) to three different types of traffic lights with countdown displays (SCD) and assess their effects on road safety and capacity. This comparison is required because the results found in the literature are divergent among countries and cities, and one of the SCD analyzed in our stud

19. Operation Efficiency Assessment Model of Route Network in Terminal Area
ABSTRACT: Terminal area is an important part of airspace system. Its operation efficiency is related to the safety, order and efficiency of the entire air traffic. So the assessment of the terminal route network operation efficiency is needed. Considering the aspects of route segment capacity, flight flow, workload and operation stability, the paper analyzes

20. Factors affecting road crash modeling
Abstract Road accident fatalities have been on an increasing trend for the last decade or so in India. Hence traffic safety management has emerged as a topic of discussion for researchers all over the world. Hence accident modelling on different factors causing them has to be conducted. Accident modelling helps us to know the real causative agents behind an

21. Robust evaluation of time since awakening using force platform posturography
INTRODUCTION: Sleepiness is responsible for a considerable proportion of traffic accidents. It is thus an important traffic safety issue to find a robust, objective and practical way to estimate the amount of time a person has been awake. To attempt to meet this goal, we investigated the relationship between sleepiness and posture control. METHODS: Subjects

22. A path-following driver/vehicle model with optimized lateral dynamic controller
Reduction in traffic congestion and overall number of accidents, especially within the last decade, can be attributed to the enormous progress in active safety. Vehicle path following control with the presence of driver commands can be regarded as one of the important issues in vehicle active safety systems development and more realistic explanation of vehic

23. Eficácia da restrição de velocidade e outras ações na prevenção de acidentes em travessias urbanas de rodovias / Effectiveness of speed restriction and other measures in the prevention of accidents at urban highway crossings
The urban highway crossings are a critical place for occurrence of traffic accidents. Thus, several engineering measures are employed to reduce the number and severity of accidents. However, there are few studies about the effectiveness of these actions. In this study two methods were used to evaluate the effectiveness, through observational studies, they ar

24. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c
