Additionally, ‘careless operation’ at the intersection is associated with alcohol-involved drivers. Most of the nighttime pedestrian crashes at segments are associated with roadways with no physical separation and the absence of streetlights. Driver alcohol involvement and their physical condition (inattentive/distracted) are also associated with pedestrian crashes associated at the segment location at night. Other segment pedestrian crashes are linked to the interstate in dark conditions, open country locations, and high-speed roadways. Additionally, the crash site investigation identified several critical pedestrian safety concerns including the lack of crosswalk facilities, high driveway density, and pedestrian behavioral patterns (e.g., crossing at roadway segments close to the intersection location). The findings of this study can be used for selecting the appropriate countermeasures based on a case-by-case basis. The exposure patterns can be used in educational campaigns to strategically reduce nighttime pedestrian crashes.]]> Mon, 16 Oct 2023 14:01:22 GMT https://trid.trb.org/View/2249066 Bayesian multivariate spatial modeling for crash frequencies by injury severity at daytime and nighttime in traffic analysis zones https://trid.trb.org/View/2204582 Mon, 25 Sep 2023 14:46:43 GMT https://trid.trb.org/View/2204582 Lighting For Pedestrians: Essential Considerations For Complete Streets Planning And Design https://trid.trb.org/View/2239859 Fri, 15 Sep 2023 10:30:50 GMT https://trid.trb.org/View/2239859 Modeling effects of roadway lighting photometric criteria on nighttime pedestrian crashes on roadway segments https://trid.trb.org/View/2233703 1.0 fc), the relative likelihood of nighttime pedestrian crashes on midblock segments in Florida tends to be reduced by 77.5% (CMF = 0.225), 81.2% (CMF = 0.188), and 85.5% (CMF = 0.145), respectively. A poor uniformity (illuminance standard deviation ≥ 0.52 fc) is likely to increase the relative likelihood of nighttime pedestrian crashes on midblock segments in Florida by 80.3% (CMF = 1.803) compared to good uniformity (illuminance standard deviation < 0.52 fc).]]> Wed, 13 Sep 2023 10:23:12 GMT https://trid.trb.org/View/2233703 Using unsupervised learning to investigate injury-associated factors of animal-vehicle crashes https://trid.trb.org/View/2186805 Fri, 01 Sep 2023 15:26:12 GMT https://trid.trb.org/View/2186805 Assessment of Safety Benefits of Technologies to Reduce Pedestrian Crossing Fatalities at Midblock Location https://trid.trb.org/View/2196805 Wed, 14 Jun 2023 11:57:00 GMT https://trid.trb.org/View/2196805 Temporal instability and age differences of determinants affecting injury severities in nighttime crashes https://trid.trb.org/View/2132283 Fri, 07 Apr 2023 13:34:29 GMT https://trid.trb.org/View/2132283 A Heterogeneity-Based Temporal Stability Assessment of Pedestrian Crash Injury Severity Using an Aggregated Crash and Hospital Data Set https://trid.trb.org/View/2117765 Thu, 23 Feb 2023 09:21:24 GMT https://trid.trb.org/View/2117765 Forecasting time trends of fatal motor vehicle crashes in Iran using an ensemble learning algorithm https://trid.trb.org/View/2096459 Tue, 14 Feb 2023 09:29:07 GMT https://trid.trb.org/View/2096459 A Study on Light Source Characteristics of Nighttime Highway Foggy Section Based on Driving Visual Cognition Demand https://trid.trb.org/View/1989430 Tue, 13 Dec 2022 10:05:36 GMT https://trid.trb.org/View/1989430 Travel Time Based Performance Measures to Assess the Effect of Crashes by Severity https://trid.trb.org/View/1989419 Tue, 13 Dec 2022 10:05:35 GMT https://trid.trb.org/View/1989419 Crash Characteristics for Classic/Historic Vehicles and Comparisons to Newer Vehicles https://trid.trb.org/View/2052738 Mon, 21 Nov 2022 16:19:22 GMT https://trid.trb.org/View/2052738
