dc.description.abstract In Sri Lanka, most of the motorbike-pedestrian accidents happening in the night time are due to the insufficient visibility of pedestrians. Even though number of researches has been carried out globally regarding improving pedestrian visibility at night for other vehicles, unfortunately few researches have been carried out for motor bikes. In this study, factors affecting the recognition of pedestrians at night such as clothing colour of the pedestrian, rider’s age, rider’s gender and head light beam condition of the motor bike are considered. For this study white, black, green and red colours were considered as pedestrians clothing colour and four age groups of riders were taken into account. Moreover, head light beam condition of the motor bike was also regarded as head or dim. Experiment was carried out to find the visibility distances in relation to above mentioned factors and data collection method was time duration method and visibility distances were calculated with the help of measured time duration and speed of the motor bike. Experiment was carried out for constant speed of 30 kmph. Findings revealed that the rider’s pedestrian recognition distance is affected strongly by the clothing colour of the pedestrian, head light beam condition of the motor bike and rider’s age. Rider’s gender does not affect pedestrian recognition distance strongly. It was also revealed that Black pedestrian clothing cannot be identified by the rider at a long distance in comparison to other colours. Meanwhile, green and red pedestrian clothing were identified in average distances. Findings showed that white can be identified by the rider at a longer distance than any other selected colours. Furthermore, statistical models were derived for visibility distance in the functions of considered factors. en_US
