OBJECTIVE To determine the rate of handheld mobile telephone use among motor vehicle drivers. DESIGN AND SETTING Observational study of motor vehicle drivers at three times (10: 00-11: 00; 14: 00-15: 00; 17: 00-18: 00) on three consecutive Fridays in October 2002 at 12 highway sites in metropolitan Melbourne. MAIN OUTCOME MEASURES Rates of mobile phone use overall and by sex and age group, ...

Interstate highways are a permanent and increasingly important feature of America’s rural landscape. Their impact on agriculture and rural living, which is already felt, w ill be greatly intensified in the next few years. Consider some of the overall dimensions of this new highway system. Of the 41,000 miles authorized, more than 35,000 miles are classed as rural. ( 1 ) * One-third of all count...

Introduction According to the 2011 Urban Mobility Report,1 roadway congestion cost a total of $101 billion and induced a total delay of 4.8 billion hours in the United States in 2010, with approximately 60 percent of the congestion occurring on freeways. Strategies have been implemented t...

1 Regional location factors, with measures of regional accessibility foremost among them, 2 exert a strong influence on urban property markets. While accessibility represents an important 3 regional-scale factor, more local influences such as proximity to urban highway links may 4 also positively or negatively influence the desirability of a location. In this paper, we use a 5 cross-section of ...

ITE JOURNAL ON THE WEB / MAY 1999 OVER THE PAST DECADES traffic volumes have been steadily increasing throughout the United States causing more congestion and compromising safety. Highway incidents can cause significant disruption to traffic flows, and their adverse effects are usually widespread. The long delays usually experienced as a result of these incidents reduce productivity and increas...

The application of finite mixture regression models has recently gained an interest from highway safety researchers because of its considerable potential for addressing unobserved heterogeneity. Finite mixture models assume that the observations of a sample arise from two or more unobserved components with unknown proportions. Both fixed and varying weight parameter models have been shown to be...

37 INTRODUCTION As drivers age, the skills necessary for safe driving, such as vision, reflexes, flexibility, hearing and reaction time, begin to deteriorate. To cope with these changes, many drivers choose to adjust their driving habits as a means of retaining their mobility. Adjusting driving habits is one part of the puzzle; improvements to the roadway environment can be another. Traffic eng...

this paper presents a hybrid approach to developing a short-term traffic flow prediction model. in thisapproach a primary model is synthesized based on neural networks and then the model structure is optimized throughgenetic algorithm. the proposed approach is applied to a rural highway, ghazvin-rasht road in iran. the obtainedresults are acceptable and indicate that the proposed approach can i...

The driver gap acceptance and rejection behavior during mandatory lane changes on a multilane freeway are analyzed in this paper. Gaps are accepted or rejected based on comparison with a minimum value generally defined as the critical gaps. Critical gaps are estimated based on the accepted and rejected gaps observed in the field. Driver behavior can be classified as consistent or inconsistent o...
