Luminance deficiency of road lighting is one of the primary reasons for night-driving risk. The randomness and uncertainty of accidents caused by luminance deficiency have increased due to vehicle liquidity, and it causes difficult in accident analysing and preventing. In order to ensure lighting safety for night-driving vehicles, according to relevance between lighting intensity and visibility and streetlamp location principle, MATLAB was used to optimize road lighting evenness model. Compared with optimization model analytical data, night luminance of forty-two main roads in Harbin was measured actually by TES-1336A digit luminance acquisition system. The model can effectively design parameters selection of road lighting. The standpoint that luminance evenness is one of the indirect reasons for traffic accident is provided in this paper. Then theoretical basis of streetlamps modification projects for visibility deficiency roads and night-driving accident analyse was established.
