It is clear from the results of many state and local government initiatives that offering incentives for green choices leads to far greater compliance, at a lower cost, than the imposition of rules and regulations.

WAYFINDING ERRORS WHILE DRIVING*1 Peter C. Burns Department of Human Sciences, Loughborough University, LE11 3TU, U.K. Available online 9 April 2002.
Abstract There is evidence to suggest that wayfinding problems represent a threat to driver safety and mobility, lead to wasted time and fuel, contribute to traffic congestion and cause drivers stress and embarrassment. Certain groups of drivers, such as the elderly, are more likely to experience difficulties navigating. A study was conducted to investigate the problems that drivers experience while trying to find their way. A postal questionnaire survey of U.K. drivers, aged 21 to 85, was conducted (n=1184). A model was developed to explain the navigation process while driving and identify the types of errors that occur. Wayfinding errors were found to be mistakes caused by a lack of appropriate information and constraints on driver decision-making. Elderly and female drivers tended to perceive wayfinding as being more difficult than nonelderly and male drivers. However, elderly drivers did not experience more frequent wayfinding problems. Solutions to wayfinding problems in general should be directed at improving road signs to support more accurate situation assessment and decision-making. *1 B. PeacockW. Karwowski

LAMP COLOR AND VISIBILITY IN OUTDOOR LIGHTING DESIGN Ian Lewin, Ph.D., FIES, L.C.,  Lighting Sciences Inc., The Illuminating Engineering Society of America has made considerable progress defining the factors that affect visibility at night. The IESNA/ANSI Recommended Practice for Roadway Lighting, Publication RP8, defines a method for designing roadway lighting based on the visibility it creates, rather than simply the amount of light a system provides. However, another important factor needs to be considered: The spectral distribution of the light source has been shown to be an important factor in visibility under outdoor lighting conditions....
