Source: LA Metro, General Transit Feed Specification GTFS Data. Note: Data is normalized and volumes are not comparable. There are complex relationships between conventional public transit systems and emerging on-demand ride-sharing services in terms of demand patterns. Ridership for the transit system is reflective of commuting patterns, with demand peaks

Source: Adapted from C. Gardner (2011) Old Urbanist. Density on the Ground: Cities and Building Coverage. Refers to density within city limits. Includes open parking areas. The larger share of parks in New York is attributed to Central Park. The footprint occupied by urban activities is reflective of their importance

Author: Dr. Jean-Paul Rodrigue The specialization index and the location coefficient look at the level of concentration of an activity at a location such as a terminal in relation to a group of locations. 1. The Specialization Index In transport, to find out if a terminal is specialized in the

Source: MarineTraffic, 2018. Note: Port time is defined as the difference between the time the ship enters the port limits (excluding anchorages) and the time that the ship exits those limits. Irrespective of whether the ship’s visit is related to cargo operations or other types of operations (e.g. bunkering, repair,

Global trade connectivity can be understood at three interdependent scales, each representing a component of connectivity.

Transportation supports a range of spatial constructs associated with several scales of interaction investigated by transport geography.

Lower and higher margins are estimated measurement errors related to the average. Through geological times, sea levels have fluctuated, implying

An average 1.5-ton car comprises about 100 systems (e.g. engine, transmission, cooling, steering, braking, etc.) and between 8,000 and 10,000 different components. In relation to the total mass, ferrous metals (steel), plastics, and aluminum account for 81%. This material intensity is associated by strong demands generated by the car industry

Source: Adapted from Tioga Group (2004). The selection of a transportation mode is the outcome of several factors, cost being important, but also the level of service, frequency, and the general value of time attributed to the cargo being transported. Thus, it is a general trade-off between cost and value
