We have evaluated the spatial dependent colorimetric parameters on a LED lighted expressway and an experimental road by both in-field measurements and simulations. Based on the theory of multivariate normal distribution, we have defined the chromaticity difference du’v’ and corresponding ellipse to analyse the measured and simulated results. The du’v’ is successively influenced by model, distance, and height of the luminaires. The highly correlated colour rendering indexes of CRI and CQS are above 70 for all measurements. These practical results were expected to provide as references for the design and construction of LED lighted roads.
