Presentation outline TRPC Smart Corridors project overview DTA model development using DYNAMEQ TRPC Modeling set up and vision I-5/US 101 Interchange Feasibility Study Where do we go from here?

Geography THURSTON COUNTY SMART CORRIDORS

SMART CORRIDORS PROJECT OVERVIEW To improve multimodal traffic operations on the corridors. Analyze operational needs Evaluate alternatives such as signal coordination and transit signal priority Investment strategy So, what tool do we use? Traffic operations at a regional scale DTA MODEL

DYNAMEQ DTA model development Import regional model from EMME Network refinements: Intersection controls and geometry Signal timing data for about 80 signalized intersections Centroid loading points OD Trip Matrices: SOV, HOV, Trucks PM Peak 1-hour trip tables from EMME 30-minute shoulders Calibration/Validation: Link counts and Intersection turning movement counts Travel time and speed data Lane queues

Simulation results OUTFLOW DENSITY

TRPC Models set up and vision EMME MODEL DYNAMEQ MODEL 4-step model Long range planning Land use and policy evaluation Smart Corridors Corridor study Traffic operations ITS evaluation Air Quality Subarea model Licensing issue Core urban area

I-5/US 101 Interchange Feasibility Study Key system Interchange Safety and mobility issues To identify existing and future needs Analyze a range feasible alternatives - Capital improvements Ramp metering Shoulder running

I-5/US 101 STUDY NETWORK REFINEMENTS Subarea Model Smart Corridors Model

Dta assignment Trip Tables Convergence Modes: SOV, HOV, Trucks PM Peak Period - 2 hours PM peak hour demand from EMME model 30 minute shoulders Peaking factors Convergence

ALTERNATIVES ANALYSIS BRAIDED RAMPS

RESULTS – MANDATORY LANE CHANGE

RESULTS – QUEUE LENGTHS

RESULTS – NODE DELAYS

RESULTS - DENSITY

CONCLUSIONS AND NEXT STEPS DTA model and Planning for Operations DYNAMEQ and opportunity for the jurisdictions to integrate signal coordination efforts Data needs Subarea – can we fill the donut hole back? Best practices to coordinate EMME/DYNAMEQ model developments
