Vehicle driver and powered two-wheeler (PTW) rider eye-height is one of the key factors in highway design, as they can determine sight distances, one of the key factors in geometric design. Different vehicle types and driving conditions can affect the eye-height. While a large number of studies have focused on the determination of passenger car and truck driver eye height, only a small number of studies have attempted to determine the eye-height of two wheelers. The objective of this research is to investigate the parameters that affect PTW rider eye-height and determine appropriate values. A multiple-camera experimental design was developed for the measurement of PTW eye height. Two arteries with different characteristics (one freeway and an urban arterial) were chosen for the data collection. The collected data are analyzed and conclusions are drawn regarding the rider eye-height for different PTW types and classes. The relation between eye height and speed is specifically investigated and it is concluded that rider eye-height is not negatively correlated with PTW speed. Directions for future research are outlined; these include additional studies under different conditions and the collection of richer data sets (e.g. including data on the riders and the PTWs).
