Effects of Roadway Lighting Level on the Pedestrian Safety
The level of roadway lighting is an important factor for the safety of roadways during the nighttime, especially for pedestrians. Past studies have shown that over fifty percent of pedestrian crashes occurred during nighttime. Most of these were fatal and severe injury crashes. These results make it clear that proper design and timely maintenance of street lighting will definitely help improve the safety of the roadway system. To evaluate the roadway lighting systems and maintain their functionality, it is essential to perform field lighting measurements. Currently, field measurements of roadway lighting systems are often conducted by handheld light meters at a short sample section of roadways. The evaluation of an entire corridor or a longer roadway section is difficult when using the traditional manual measurement methods. This study addresses this difficulty by developing a mobile lighting measurement system that can be used to collect massive lighting level data in a safe and efficient way. In this study, a mobile lighting measurement system was developed and installed in a test vehicle to collect illuminance data along a corridor of U.S. 19 in Pinellas County, Florida. The night time pedestrian crash data were collected for a three year period. The preliminary study shows that the frequency of nigh time pedestrian crash at low lighting level segments is much higher than those segments with a high illuminance level.
