Fundamentals of transportation engineering

Page Correction Chapter 1 14 Example 1.2. Question C should read “C. At what value of time (VoT) would the two flight...” 17 Figure 1.10. 2 level. “Airplane” should be “Air” because we are talking about the “way.” Also, non-motorized modes do not belong in the 2 level. Non-motorized transportation modes, walking and biking, are “modes” that use highways (or streets) which are the “way.” 30 Table 1.6. Column 10 Lane Miles. For 1990, it is 49.2 miles instead of 49 miles (12.3 miles x 4 lanes = 49.2 miles) 30 Trend discussion 2. “The freeway expansion...by about 29 percent.” Actually if you compute it, it is 31 percent [(64.6-49.2)/49.2x100 = 31.3%]. 64.6 miles = 12.3 miles x 4 lanes + 7.7 lanes x 2 lanes (widening). 31 In the first paragraph right above SUMMARY. “...derived from the Table 1.5 and ...” should be “...derived from the Table 1.6...” Chapter 2 61 The solution section to Example 2.9. The first D formula should look like this. D = 13 veh/(468.77-468.50 mi)/3 lanes = (13/.27 vpm)/3 lanes 79 Variable definition section right below equation (2.24). (also “q” or “V”) is not needed because these variables are not used in this book with the meaning of λ. 90 6 line from the bottom of the second paragraph. “[B]reakdown occurs” should read “Breakdown occurs...” 110 Exercise 2.23. 2 sentence. “...a cumulative apparent presence time value t(P) = 294.7 seconds.” should read “...a cumulative apparent presence time value Σ t(P) = 294.7 seconds.” 114 Exercise 2.50, 2 line. “The adjacent major street ... rate of 1200 vehicles in the lane...” should read “The adjacent major street ... rate of 1200 vehicles per hour in the lane...” Chapter 3 143 1 paragraph, 2 sentence. “Tables 3.13 to 3.20 show...” should read “Tables 3.15 to 3.18 show...”
