Case Studies

MY QUESTION:

  • Is there a reduction in accidents after access management is implemented?
  • If yes, is it statistically significant?

CONCLUSIONS

  • Access Management has a significant impact on accident severity and societal costs.
  • Access Management results in a significant reduction during PM peak travel
  • This knowledge can be helpful when programming future projects.

Three Examples from a Developer’s Perspective

  • A 15 acre +/- development that was ultimately denied as they could not secure reasonable access to accommodate the site traffic.
  • A redevelopment project that was ultimately approved though unable to meet any of the access management standards.
  • An approval to allow additional access to support an existing development and improve on-site circulation concerns

Themes

  • Cities believe in the importance and value of access management
  • Access management has to be undertaken hand-in-hand with other municipal considerations
  • Access management is one of a handful of tools that should be used for the betterment of the community

Municipal Realities

  • Cities are a study in conflicting goals and compromises
  • Rarely does one goal trump all others . . . even the safety goal!
  • Politics is a daily issue
  • Balancing needs is key to success
