The first site was 7.5 miles in length with an Annual Average Daily Traffic (AADT) of 7,400. Over the year-long study period, 42 crashes occurred on this portion of roadway, 5 of them resulting in fatalities. The second site was a 14-mile section with an AADT of 4,700. There were 67 crashes in this section with 5 fatalities. Determine the appropriate crash rates for both locations, and discuss the implications.arrow_forward

- What safety precautions are taken during handoffs between vehicles?arrow_forwardA black spot funding program prioritised a project for widening a two-lane rural highway from 5.4 (=2x2.7) m to 6.6 (=2x3.3) m. This project aimed to reduce a particular set of CMF-related crash types such as single-vehicle-run-off-the-road and multiple-vehicles-head-on, opposite direction sideswipe, and the same direction sideswipes. Therefore the CMFs for lane width on the roadway segment given in Table 5.14 (Text 5.1) apply. Compute the expected average total crash frequency after the widening for the following conditions. The expected average crashes before widening = 25 total crashes/year. AADT on the highway segment, before widening = 1150 veh/day AADT on the highway segment, after widening = 1750 veh/day Proportion of total constituted by CMF-related crashes is 0.574. Answers: Expected average crash frequency after widening = total crashes/year Report your answers to the closest two decimal places without units (i.e., if your answer is 10.258, you should enter 10.26 or if your…arrow_forwardreport highway lab "Flash & Fire Point Test" same quations 1)Define flash point and fire point?2)What are the applications of flash and fire point test?3)Differentiate between flash point and fire point?4)Briefly out line the test procedures of Flash point and Fire pointarrow_forward
