Paper format. National Examinations — May 2019, 16-Civ-B10 Traffic Engineering, 3-hour duration, OPEN BOOK (any non-communicating calculator permitted). Seven questions over four pages; a total of five solutions is required and all questions are of equal value (20 marks each). Grading scheme printed on page 1: Q1 (a)–(e) 4 marks each; Q2 20 marks; Q3 20 marks; Q4 (a)–(e) 4 marks each; Q5 (a) 6 marks, (b) and (c) 7 marks each; Q6 (a)–(e) 4 marks each; Q7 (a)–(h) 2.5 marks each. All seven questions are solved here, because the set is a study resource rather than a timed attempt. The paper's own NOTE 1 invites a clear statement of assumptions and NOTE 2 permits any datum not given to be assumed — both are used below and every such assumption is flagged.
