In this paper it is examined the validity of luminance-to-illuminance conversion factor in the roadway lighting design. Luminance and illuminance distribution patterns were measured to yield the calculated conversion factor on the newly-constructed highway, and this value was compared to the conversion factor commonly used. We found that some discrepancy might exist between them due to difference in the values between the luminance yield factor and the coefficient of utilization. Therefore this fact must be fully understood in the roadway lighting design process.
