In this paper various categories of road users have been identified. Earlier studies of inline skates, scooters, strollers, electric bicycles, adult tricycles . Characteristics of the Driver, the Vehicle and the Road Driver Characteristics In 1992, there were 173 million licensed drivers. HV[r0. Before going into that, the question arises, what is Traffic Engineering!? The highest number of persons involved in road crashes are aged 41-60 years (39.3%) followed by age above 60 years (32.3%) in the pedestrian category. Discriminant analysis and . Traffic controls could be easily designed if all drivers reacted to . 0000015446 00000 n Fatigue causes drowsiness or sleep. 423 0 obj <> endobj While going from light to dark, the human eye requires more time for adaptation. They take up various roles like drivers, pedestrians, cycles etc and assess the conditions in their own unique way. No one likes to spend hours caught up in a traffic jam. Required fields are marked *. The traffic stream may consist of mixed traffic or heavy traffic whereas facilities to overtake to the faster vehicles may be limited. Self-explaining roads lead road users to behave in a way that road planners and designers expect, thereby resulting in low crash rates. %PDF-1.4 % Including mountain, road, urban, fitness bikes and much more. b) The physical, mental and emotional characteristics of humanbeings are to be given particular attention. The seats are made with dimensions of 0.4-0.5 meters wide and 1.5 meters long. 9.6% of the drivers involved in fatal accidents were unregistered. Psychological characteristics includes emotional factors (anger, fear and anxiety), environmental factors include atmospheric and traffic stream conditions. In visual characteristics, the field of vision explained before is of primary consideration. One of the statistics says that one percent of reported road accidents are due to drivers being asleep. Road users play an important role in studying traffic engineering. What are the characteristics of a good traffic control? Vision The field of vision includes acute or clear vision cone, fairly clear vision cone and peripheral vision cone as shown in the figure below.
