| |CHAPTER 1 TRANSPORTATION BASICS |
| | |
| |CHAPTER 2 TRAFFIC FLOW: THEORY AND ANALYSIS |
|123 |Heading in Table 3.9 should be “Decrease in Average Travel Speed (mi/hr)” |
| | |
| |CHAPTER 3 HIGHWAY DESIGN FOR PERFORMANCE |

| |CHAPTER 4 MODELING TRANSPORTATION DEMAND AND SUPPLY |
| | |
| |CHAPTER 5 PLANNING AND EVALUATION FOR DECISION-MAKING |
|270 |In Example 5.6, EUAB-EUAC for Project A at d = 5% should be $360,000. At d = 10%, it should be $248,000. In the calculation for |
| |Project A5%, “140,000” should be “240,000”. |
|271 |Project A10% EUAB – EUAC = $148,000 $248,000 |
| | |
| |CHAPTER 6 SAFETY ON THE HIGHWAY |
|312 |Equation (6.3) should be [pic], where m = million entering vehicles or million vehicle-miles. |
|312 |In Example 6.3, insert a second sentence that says “Approximately 9.04 million vehicles enter the intersection in an average year.” |
|313 |In the Solution to Example 6.3, the calculations should be: [pic][pic]. Below the calculations, replace “(9.35)” with “(9.04)” and |
| |“(9.82)” with “(9.84)”. |
|341 |Replace Equation (6.15) and revise the sentence preceding it. “The time needed to go from vo to vf on a level roadway, is |
| |[pic] (6.15)” |
|341 |Just before equation (6.16), “If braking takes place on a hill with a positive (uphill) grade G, the braking distance will be” |
|367 |Stopping on a downhill grade. At one point on SR835, there is a 4.9 percent downhill grade. How long much distance and time will it|
| |take to bring a car traveling at 48 mph to a stop on that downhill segment if the driver’s reaction time is 2.0 seconds and f = 0.29?|
| |CHAPTER 7 HIGHWAY DESIGN FOR SAFETY |
|407 |22 Oct 2012: In Example 7.19, Ls from (7.26) should be 141.75 ft, not 141.5 ft. |
| | |
| |CHAPTER 8 DESIGN OF INTERSECTIONS FOR SAFETY AND EFFICIENCY |
|434 |22 Oct 2012: In Figure 8.11, the entries in cells A11 to A21 should be: |
| |44.00 |
| |v(0) = approach speed (ft/sec) |
| | |
| |66.00 |
| |x(r) = reaction distance (feet) |
| | |
| |4.40 |
| |t(s) = time to stop (sec.) |
| | |
| |96.80 |
| |x(b) = braking distance (feet) |
| | |
| |162.80 |
| |x(s) = stopping distance (feet) |
| | |
| |176.00 |
| |x(Y) = dist. Traveled during Yellow (feet) |
| | |
| |16.00 |
| |L = length of vehicle (ft.), if desired |
| | |
| |238.80 |
| |x(c) = distance to clear intersection (feet) |
| | |
| | |
| |x(c) = x(s) + W + L |
| | |
| |Results: |
| | |
| | |
| |62.80 |
| |x(DZ) = x(c) - x(Y) = [x(s)+W+L] - x(Y) |

| |CHAPTER 9 HIGHWAY DESIGN FOR RIDEABILITY (PAVEMENT DESIGN) |
|509 |(11/06/2012) Add to REFERENCES, between [2] and [3]: |
| |American Association of State Highway and Transportation Officials (AASHTO), Guide for Design of Pavement Structures, 4th Edition, |
| |1993 |
| | |
| |CHAPTER 10 PUBLIC MASS TRANSPORTATION |
|523 |(4/15/2012) Equation 10.10a includes braking. Some problems – like Exercise 10.8 -- include only acceleration from a stop until Vtop|
| |is reached, then coasting to a complete stop. A new equation (10.10b) is needed for this case: [pic]. |
|524 |(4/16/2012) Add and revise after Equation 10.10 (now 10.10a): If braking is not a factor in the analysis – only acceleration and |
| |coasting occur before Vec is reached -- the corresponding equation is |
| |[pic] (10.10b) |
| |Equations (10.10a) and (10.10b) apply only to cases in which there is no constant speed regime. Equations (10.10a) and (10.10b) are |
| |important calculations to do early in an analysis, if a coasting regime is being considered. |
|528 |(4/14/2012) In Cell C17 of Table 10.3, “15.4” must be “10.6”, because the braking begins after coasting has ended. Use Equation |
| |10.7b, not 10.7a. |
| | |
| |CHAPTER 11 AIR TRANSPORTATION AND AIRPORTS |
|582 |In the solutions to Example 11.4, “1542” should be “1562”, causing the following changes: |
| |Including the time for the first aircraft to take off, the total elapsed time is 1542 1562 seconds or 25.70 26.03 minutes. |
| |To calculate the capacity (ops/hr) of GTN during the period studied, first compute 1542 sec/20 ops = 77.1 sec/op 1562 sec/20 ops = |
| |78.1 sec/op. Then (3600 sec/hr)/(77.1 sec/op) = 46.7 ops/hr (3600 sec/hr)/(78.1 sec/op) = 46.1 ops/hr. |
| | |
| |CHAPTER 12 MOVING FREIGHT |
|687 |Early printings of Edition 1 had Example 12.10 correct. See values in bold font. |
| |Example 12.10 Ruling grade and train speed |
| |Assuming the ruling grade in this series of examples is 0.75 percent, at what speed will a train with four 5000 horsepower |
| |locomotives (efficiency at 85 percent) be able to climb that grade? Use 1200 lbs resistance per locomotive. |
| |Solution to Example 12.10 |
| |From Equation 12.6, the resistance due to the grade G = 0.75 is Rgrade = 20 * 0.75 = 15 pounds per ton. This Rgrade value is added |
| |to the Rtt expression used in Example 12.8, which must be adjusted for a speed V that is now unknown. |
| |[pic]16.6 + (0.01 * V) + (0.002 * V2) |
| |Recalling Equation 12.8, Rtotal = [(Rtt + Rgrade) *(C*w*n)] = TEdrawbar: |
| |TEdrawbar = (0.002 V2 + 0.01 V + 16.6) lbs/tons * 80 cars * 80 tons/car = (12.8 V2 + 64 V + 106,240) lbs |
| |Four 5000 HP locomotives provide power at 85 percent efficiency and speed V (mph), but they also add (1200 * 4) lbs of resistance. |
| |The resistance-propulsion relationship (with Equation 12.11 on the righthand side) becomes |
| |12.8 V2 + 64 V + 106,240+ (1200 * 4) = [pic] |
| |Rearranging terms produces 12.8 V3 + 64 V2 + 111,040 V = 6,375,000. V = 45.4 mph. |
|692 |(11/30/12) In the second line of the Solution to Example 12.13, 201.83 should be 201.825. As a result, Rsf = 292,892 and RWM = |
| |117,108. Raero should be 4896 lb, making Rtotal = 414,896. |
|697 |(12/30/12) In the Solution to Example 12.20, the correct equation for p is [pic]. The [pic]in Equation 12.24 was mistaken for a |
| |“/”. |
|699 |(12/30/12) Equation (12.27) should be [pic] |
|700 |(12/30/12) Example 12.22 should refer to Example 12.20.not Example 12.19. |
