Abstract:Dallas, TX; Minneapolis, MN; and San Diego, CA could not be more different in many
ways. However, they share at least one similarity: they all have congested multimodal
transportation corridors. In an effort to improve travel conditions, all three of these cities are
designing integrated corridor management (ICM) systems in their busiest corridors.
In 2010 stakeholders in Dallas,
Minneapolis, and San Diego
conducted analysis, modeling
and simulation (AMS) to
explore whether applying ICM
strategies to a corridor could
improve performance and
to assess their planned ICM
strategies. AMS results in all
three corridors suggest that ICM will increase reliability while reducing travel time, delays,
fuel consumption, and emissions. Benefit-to-cost ratios for ICM were shown to range from
10:1 to more than 20:1 over the life of the ICM system. Furthermore, the benefits of ICM
appear to scale with travel demand and are especially meaningful under scenarios that
unexpectedly constrain supply, such as traffic incidents.
