Abstract

In accordance with “Guideline for creation of safety and comfort bicycle environment” established in 2012, bicycle lanes has been implemented all over Japan. Various types of bicycle lanes, painted other than blue, painted only a part of lanes and so on, have been seen because the guideline allows various method for coloring them. In implementation of bicycle lanes, it is considered that it is desirable not only to provide visibility for drivers but also consideration for the landscape of a circumference and environment. This paper, therefore, examined influences of a method for coloring on its visibility and landscape. We focus on painted color (blue, colcothar and green), width of bicycle lanes (1.0m, 1.5m and 2.0m), painted area of bicycle lanes (entire, both ends and one end), and interval of arrows on bicycle lanes (20m, 40m and none), and the influences of these on visibility and landscape have been examined by a driving simulator and a questionnaire survey.
