Question

For each of the listed modes of transportation, estimate typical values for the following parameters:
vehicle capacity [passengers]
vehicle speed [mile/hour]
minimum vehicle headway [seconds/vehicle]
maximum vehicle flow [vehicles/hour]
maximum passenger flow [passengers/hour]

The purpose of this exercise is to make crude comparisons of magnitudes, so estimates within a factor of 2 are sucient. You are not expected to collect data or research values, but you should make reasonable and consistent estimates based on what you know about these modes.

(a) Bicycles in a bike lane
(b) Cars on a lane of highway
(c) Cars on a city street
(d) Express bus in a dedicated lane of highway
(e) Local bus on a city street
(f) Light rail train (2 cars long) in the median of a street (e.g., Boston's Green Line)
(g) Subway train (6 cars long) operating in a tunnel (e.g., Boston's Red Line)
(h) Commuter train (6 cars pulled by a diesel locomotive) cee 410/510
