Which оf the fоllоwing stаtements аbout vаccines is FALSE?
A multinоmiаl-lоgit mоde choice model hаs been estimаted to determine the split in person-trips among three modes: drive-alone (DA), shared-ride (SR), and transit (TR). The following are the utility expressions: The probability of choosing the transit mode is: Pr(TR) = 1. The total demand for travel from a residential zone to the CBD = 1000 person trips. Assume the following “base-level” transportation system characteristics and calculate the transit ridership and revenue under this base case scenario. 2. To alleviate congestion and improve air-quality, two options are proposed: (a) “Free Transit” – there is no charge to ride the transit (cost = 0 and IVTT and OVTT for transit remains at the base level). (b) “Frequent Transit” – increase the frequency of the buses so that the travelers’ OVTT for transit is reduced to 12 minutes (IVTT and Cost for transit remains at the base level). The service characteristics of the other two modes (DA and SR) remain at base level under all scenarios. Considering transit ridership and revenue under the base case and the two scenarios, which one would you recommend? Show relevant calculations.
