TNC Research Questions

Impact on transit and other mode choices
  • Are TNCs shifting trips from transit? Which trips?
  • Are people sharing rides?
  • What is the impact on personal vehicle ownership and usage?
Impact on congestion
  • Are TNCs causing increased congestion? And how? (double parking, dwelling/loitering; increased vehicle trips; extra VMT between trips)
  • How many trips are during congested time and in congested areas?
  • Are TNCs creating new trips or increasing the capacity of existing vehicle trips?
Impacts on curbside uses
  • What is the impact on parking demand and revenues? Asked with an eye toward the potential for charging for TNC access
  • PUDO zone effectiveness
  • Curbspace allocation (part of the analysis with other modes)
Safety
  • Driver safety - more or less crashes?
  • PUDO activity - pedestrian impacts?
  • Decreased DUIs?
Equity: providing access for all?
  • Who is using TNCs? Are all areas, ages, and abilities able to use? Are there differences in their usage?
  • Are TNCs filling system gaps?
