MOTORCYCLE AND BIKE BOXES ATTRIBUTES TOWARD SAFETY PREFERENCES OF CYCLISTS

Abstract

Motorcycle and bike boxes are installed at signalized intersections to enhance the safety of cyclists and motorcyclists. However, there is a lack of research focusing on the attributes of motorcycle and bike boxes that influence cyclists’ perceived safety. This study investigates cyclists’ safety preferences using a Stated Preference (SP) approach. Respondents were asked to compare two alternative designs of motorcycle and bike boxes with varying attributes (including shape, size, color, signage, entry lane configuration, Traffic Arrows and Lane Marking Lines, intersection entry speed, and vehicle volume) and select the one they perceived as safer. Data were collected from 400 cyclists through an online questionnaire consisting of eight scenario sets, each comparing two different motorcycle and bike box designs. The data were analyzed using a Binary Logit Model. The results revealed that factors influencing safety preferences include P-shaped designs, extended box length, Installation of Traffic Arrows and Lane Marking Lines, surface coloring, and reduced vehicle speeds when entering intersections. These findings can support the design and implementation of motorcycle and bike boxes that better align with cyclists’ safety expectations.
