Presentation overview

  • What drives future traffic

growth – overview of assumptions

  • Changes to the

transportation network – assumed improvements

  • Forecast traffic volumes

along key corridors

  • Next steps
  • Questions

Future travel demands

  • Population and employment are expected to

grow by more than 25% by 2035

  • Future travel demand will grow with population

and economic activity

  • Vehicle trips will not grow as significantly due to

transit expansion and tolling

  • Truck activity will grow faster than regional traffic
  • Street network will remain much the same

except for programmed projects and SDOT changes in managing streets for transit, bicycles, and passenger rail

What drives future traffic growth?

Passenger Vehicles Non-Port Trucks Port Trucks

  • Population and employment growth
  • Changes in land use and modal options

Vehicle mode Reasons change occurs

  • MIC industrial growth
  • Changing industry composition
  • Trade growth and intermodal shifts

Non-port truck trips growth

  • MICs will comprise an increasing share of

regional goods movement dependent industry activity

6

  • Output and demand from goods movement

dependent industries is growing faster than employment – productivity gains

  • As a result, non-port truck trips will grow faster

than overall regional traffic

  • Construction
  • Natural Resources
  • Manufacturing
  • Wholesale
  • Transportation
  • Utilities
  • Retail
  • Food Services

Transportation network changes

  • Improvements to the

transportation system will change routing patterns

– New projects – T

  • Shifting routes of auto trips and changes in

congestion will impact truck routing
