Example Assuming shopping, social/recreational, and work vehicle- based trips all peak at the same time (for exposition purposes). Determine the total number of peak hour trips (work, shopping, social/recreational) using the generation models described in the previous two examples.

Solution: For vehicle-based shopping trips, we obtain Type 1 : 0.12 + .09(2) + 0.011(40) - 0.15(2.05) = 0.4325 trips/household x 100 households = 43.25 trips Type 2 : 0.12 + .09(3) + 0.011(50) - 0.15(2.05) = 0.6325 trips/household x 200 households = 126.5 trips Type 4 : 0.12 + .09(4) + 0.011(40) - 0.15(2.05) = 0.6215 trips/household x 50 households = 30.625 trips Type 3 : 0.12 + .09(3) + 0.011(55) - 0.15(2.05) = 0.6875 trips/household x 350 households = 240.625 trips Therefore, there will be a total of 441 vehicle-based shopping trips.

Solution: For vehicle-based social/recreational trips, we obtain Type 1 : 0.04 + 0.018(2) + 0.009(40) + .16(1) = 0.596 trips/household x 100 households = 59.6 trips Type 2 : 0.04 + 0.018(3) + 0. 009(50) + .16(2) = 0.864 trips/household x 200 households = 172.8 trips Type 4 : 0.04 + 0.018(4) + 0. 009(40) + .16(3) = 0.952 trips/household x 50 households = 47.6 trips Type 3 : 0.04 + 0.018(3) + 0. 009(55) + .16(1) = 0.749 trips/household x 350 households = 262.15 trips Therefore, there will be a total of 542.15 vehicle-based social/recreational trips.
Image of page 31
Solution: Work Trips = (1 x 100) + (1 x 200) + (2 x 350) + (1 x 50) = 1050 Total Trips = 441 + 542 + 1050 = 2033

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
