%X In the integrated traffic environment, human factor is always a main factor of the three elementary factors, besides the vehicle and road factor. The driver physiological and psychological characteristics have an important impact especially on traffic safety in urban road traffic conditions . Some typical traffic scenes in condition of urban road, such as light signal control at intersection, overtaking, and passing, are selected for condition analysis. An eye movement apparatus was used to obtain driver eye closure, blink frequency, and other visual physiological indicators in the traffic conditions of urban road. The regular patterns of driver visual characteristics in the corresponding scenes were analyzed in detail to provide data and theoretical support for the further research on traffic safety of urban environment from the viewpoint of driver psychology and behavior. 1. Introduction During recent years, the traffic accidents happened more and more frequently, which make more and more serious impacts on people¡¯s lives and the socioeconomic. The frequency of traffic accidents is especially higher in the intersection or during overtaking and passing. The traditional solution, to decrease the accident frequency in theory, mainly focused on analysis and optimization of the road alignment and the mechanics of vehicle movement [1¨C4]. The driver factor, as an important human factor besides the other factors of road and vehicle in traffic system, is seldom taken into account in the traditional research. The recent studies started to concentrate on the physical and physiological characteristics of the driver [5¨C15]. Many of them analyzed the relationship between the driver physical or physiological state and the road alignment of expressway and mountain highway. However, the driver physiological characteristics in certain environments of urban road are seldom concerned. In reality, the driver immediate reaction to the traffic conditions, which affects a lot during traffic accidents, has strong relationship with the driver physiological states that could be measured by certain professional equipment. Through measurement of some typical parameters of visual characteristic, eye closure and blink frequency, for example, in the typical condition of urban traffic, such as especially overtaking, passing, and traffic light controlling, the regular pattern of the visual characteristic can be described for further analysis and research on the relationship between the visual features and driving reaction during typical urban traffic environments.
