摘要: The Federal Highway Administration (FHWA) reported between 2016 and 2017, fatal crashes in work zones increased by 3%, while outside of decreased 1.5%. FHWA also that account for approximately 10% the nation’s overall congestion 24% unexpected interstate delays. This paper reports on a study 23 construction covered 150 centerline miles Indiana roadway summer 2019. Approximately 50% all period May to September 2019 occurred within or an approach upstream downstream one these zones. Commercially available vehicle hard-braking event data is used geofenced zone approaches limits. research examined 196,215 events over 2-month 3132 same 2018 found there were 1 crash/mile every 147 around site. R2 was 0.85. concludes recommending be agencies quickly identify emerging locations show relatively large number further evaluation.
