HighlightsLate night alcohol-related crashes, both involving drivers and pedestrians, are spatially associated with late night bars.The more concentrated are the late night bars, the greater the increase in the likelihood of an alcohol-related crash. The effect is exponential, not linear, and is particularly strong in bar clusters.The closer a road segment is to a late night bar, the greater the likelihood that there will be an alcohol-related crash.Reducing late night alcohol-related crashes will involve enforcement and land use monitoring along with providing alternative means of transportation for patrons of late night bars.

    AbstractA study in the City of Houston, Texas, related the location of establishments primarily serving alcohol (“bars”) after midnight to late night alcohol-related motor vehicle crashes. There were three data sets for 2007–09: 1) 764bars that were open after midnight; 2) 1660 alcohol-related crashes that occurred within the City of Houston between midnight and 6 am; and 3) 4689 modeling network road segments to which bars and alcohol-related crashes were assigned.Forty-five percent of the late night alcohol-related crashes were within a quarter mile of a late night bar. The bars were highly concentrated in 17 small bar clusters. Using the modeling network, Poisson-Gamma-CAR and Poisson-Lognormal-CAR spatial regression models showed a positive exponential relationship between late night alcohol-related crashes and the number of late nights bars and bar clusters, and a negative exponential relationship to distance to the nearest late night bar controlling for the type of road segment (freeway, principal arterial, minor arterial). A more general model dropped the bar cluster variable.Further, the Poisson-Gamma-CAR model appeared to produce a better representation than the Poisson-Lognormal-CAR model though the errors were different. The general Poisson-Gamma-CAR model showed that each late night bar increased the frequency of alcohol-related crashes on a segment by approximately 190%. For each mile closer a segment was to a late night bar, the likelihood increased by 42%.
