27、s report presents the principal fundamental information known about the visual task of driving at night and provides insights as to how these principals may be used to make roadways safer and improve traffic flow at night. The first chapter describes the visual task of driving and establishes the el

28、ements in the perceptual process. It then discusses how night driving differs from daylight operations. Chapter two identifies and critically evaluates how the night driver acquires information from the roadway scene and discusses what are the important cues needed for vehicular operation. The third

29、 chapter discusses the required sight distances for carrying out the three major subtasks in driving. Chapter four discusses visibility models and their potential uses. The final chapter suggests methods for improving road design for nighttime conditions. Design elements discussed include public and

30、 vehicular lighting, the use of retroreflective materials and the use of self-luminous signals.

33、te. Le dernier chapitre propose des mthodes pour amliorer la route et ses quipements pour la circulation de nuit.

Er gibt Aufschlu, wie diese Prinzipien anzuwenden sind, um die Straen sicherer zu machen und um den Verkehrsflu bei Nacht zu verbessern. Das erste Kapital

35、 beschreibt die Sehaufgabe beim Fahren und erlutert die wesentlichen Einzelheiten des Wahrnehmungsprozesses. Es wird dann untersucht, worin sich Fahrten bei Nacht von solchen bei Tage unterscheiden. Im zweiten Kapital wird kritisch untersucht, wie der Fahrer bei Nacht die Information ber das Straenb

36、ild erfat und was die wichtigsten Punkte fr das praktische Fahren sind. Das dritte Kapital untersucht die Sehweiten, die erforderlich sind, um die wichtigsten drei Unteraufgaben beim Fahren ausfhren zu knnen. Das vierte Kapitel untersucht die Sehmodelle und ihre Anwendungsmglichkeiten. Das letzte Ka

37、pitel regt Methoden zur Verbesserung des Straenbildes fur Nachtzeitbedingungen an. Die Hinweise umfassen sowohl die Beleuchtung durch ortsfeste Anlagen als auch durch Fahrzeuge, sowie die Anwendung retroreflektierender Materialien und selbstleuchtender Zeichen.

Analysis of the Night Driving Task “In areas where the primary function of the lighting installation is to provide illumination for the quick, accurate performance of visual tasks, the task itself is the start

39、ing point in the lighting design.“ - IESNA Lighting Handbook, 1972, p. 10-1 O 1.1 Introduction Driving involves the complex interaction of perceptual, cognitive and psychomotor processes and is affected by and dependent upon our capacities for learning, remembering, decision- making and selectively

40、attending. The role of visual perception in driving must be considered in the context of these interrelated processes. We obtain information from the environment pertinent to driving through all of our senses: with our visual sense by looking at the roadway environment, other vehicles, and our vehic

41、les instrumentation; with our auditory sense by listening to sounds generated from within the vehicle and from the environment outside; and with our proprioceptive senses by feeling the changes in forces acting upon our body in motion, obtained from kinesthetic and vestibular mechanisms. Nevertheles

42、s, visual feedback is the most important source of control information for human locomotion. The visual sense is the source of the most important information required in the performance of the driving task. The basic visual task of locomotion is to obtain sufficient information to navigate through t

43、he environment. During the act of driving the driver has to dynamically control the velocity, acceleration and direction of vehicular movement by observing the roadway, the boundaries marked on it, other vehicles upon it and the environment nearby and by adhering to both general and specific traffic

44、 rules recalled from memory. The dynamic aspect of control of a moving vehicle involves the visual perception of the drivers own movement relative to the roadway and its surroundings plus that of other road users relative to his/her vehicle. In addition, the driver must “think and look ahead“ in ord

45、er to better prepare for the various eventualities associated with changes in the roadway alinement and oncoming traffic. This requires bidirectional mental adjustment in space and time and the mental processes necessary to achieve this must be carried out while the immediate control processes of dr

46、iving operate in real time.“ The driver must not only adjust lane position in accordance with the vehicle directly ahead but must also anticipate the position of the pedestrian a half block away approaching the crosswalk that is coming up. In spite of the complexity of the driving task, viewed in th

47、is way, millions of individuals perform it safely every day, and with very little thought of the complexity of the information processing involved. Human vision evolved to provide information for control of the moving human body, which is capable of speeds no greater than about 15 km/h (except for t

48、he well trained runner and then, only for exceptional circumstances and/or reasonably brief periods of time). During driving, however, it is used to provide feedback for control of a vehicle capable of speeds ten times greater, often sustained for hours at a time. Because human control responses tak

49、e time to organize and execute, these greater speeds require that adaptive motor responses be made at distances much greater than are needed when walking. Form perception vision is able to provide information about distant objects and events. Consequently, there is a relative greater dependence upon visual information than on information from the other senses during driving. Locomotor and visual functions evolved together and are, consequently, matched to one another
