Title Risk compensation--the case of road lighting Type Journal Article
Year 1999 Publication (up) Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume 31 Issue 5 Pages 545-553
Keywords Lighting
Abstract The hypothesis of this article is that drivers will not adjust their behavior, i.e. drivers are not expected to increase their speed, reduce their concentration or travel more when road lighting is installed. The hypothesis was based on previous research showing that road lighting reduces road accidents and that average driving speeds do not increase when road lighting is installed. Our results show that drivers do compensate for road lighting in terms of increased speed and reduced concentration. Consequently, the hypothesis is rejected. This means that road lighting could have a somewhat larger accident-reducing effect, if compensation could be avoided. The fact that previous research has found no change in average speed when road lighting is introduced, seems to be explained by increased driving speeds by some drivers being counterbalanced by a larger proportion of more slowly driving groups of drivers (elderly people and women), i.e. different subgroups of road users compensate in different ways.

Title Risk factors affecting the severity of single vehicle traffic accidents in Hong Kong Type Journal Article
Year 2004 Publication (up) Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume 36 Issue 3 Pages 333-340
Keywords Lighting; Injury severity; Logistic regression models; Risk factors; Single vehicle accident
Abstract A population-based case–control study was conducted to examine factors affecting the severity of single vehicle traffic accidents in Hong Kong. In particular, single vehicle accident data of three major vehicle types, namely private vehicles, goods vehicles and motorcycles, which contributed to over 80% of all single vehicle accidents during the 2-year-period 1999–2000, were considered. Data were obtained from the newly implemented traffic accident data system (TRADS), which was developed jointly by the Transport Department, Police Force and Information Technology Services Department, Hong Kong. The effect of district, human, vehicle, safety, environmental and site factors on injury severity of an accident was examined. Unique risk factors associated with each of the vehicle types were identified by means of stepwise logistic regression models. For private vehicles, district board, gender of driver, age of vehicle, time of the accident and street light conditions are significant factors determining injury severity. For goods vehicles, seat-belt usage and weekday occurrence are the only two significant factors associated with injury severity. For motorcycles, age of vehicle, weekday and time of the accident were determined to be important factors affecting the injury severity. Identification of potential risk factors pertinent to the particular vehicle type has important implications to relevant official organisations in modifying safety measures in order to reduce the occurrence of severe traffic accidents, which would help to promote a safe road environment.

Title Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
Year 2018 Publication (up) Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume 119 Issue Pages 23-28
Keywords Security; Public Safety; Lighting
Abstract Reducing the potential for crashes involving front line service workers and passing vehicles is important for increasing worker safety in work zones and similar locations. Flashing yellow warning beacons are often used to protect, delineate, and provide visual information to drivers within and approaching work zones. A nighttime field study using simulated workers, with and without reflective vests, present outside trucks was conducted to evaluate the effects of different warning beacon intensities and flash frequencies. Interactions between intensity and flash frequency were also analyzed. This study determined that intensitiesof 25/2.5 cd and 150/15 cd (peak/trough intensity) provided the farthest detection distances of the simulated worker. Mean detection distances in response to a flash frequency of 1 Hz were not statistically different from those in response to 4 Hz flashing. Simulated workers wearing reflective vests were seen the farthest distances away from the trucks for all combinations of intensity and flash frequency.

Title The role of ambient light level in fatal crashes: inferences from daylight saving time transitions Type Journal Article
Year 2002 Publication (up) Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume 34 Issue 4 Pages 487-498
Keywords Public Safety; Lighting
Abstract The purpose of this study was to estimate the size of the influence of ambient light level on fatal pedestrian and vehicle crashes in three scenarios. The scenarios were: fatal pedestrian crashes at intersections, fatal pedestrian crashes on dark rural roads, and fatal single-vehicle run-off-road crashes on dark, curved roads. Each scenario's sensitivity to light level was evaluated by comparing the number of fatal crashes across changes to and from daylight saving time, within daily time periods in which an abrupt change in light level occurs relative to official clock time. The analyses included 11 years of fatal crashes in the United States, between 1987 and 1997. Scenarios involving pedestrians were most sensitive to light level, in some cases showing up to seven times more risk at night over daytime. In contrast, single-vehicle run-off-road crashes showed little difference between light and dark time periods, suggesting factors other than light level play the dominant role in these crashes. These results are discussed in the context of the possible safety improvements offered by new developments in adaptive vehicle headlighting.
