  1. Calgary Commercial Movement Model Kevin Stefan, City of Calgary J.D. Hunt, University of Calgary Prepared for the 17th International EMME/2 Conference Calgary, Alberta, Canada • October 22-24, 2003

  2. Calgary Commercial Movement Model • Nature of Commercial Movement • Basic properties • Tour-based framework • Model Structure • Choice set tree • Interface with RTM • Java microsimulation • Iterative processes

  3. Why a Commercial Model? • Represent all users of transportation systems • Consumer surplus measures • Emissions • Volumes for design and microsimulation base • Represent concerns and needs of business community

  4. Commodity Flow Survey • 24-hour business establishment travel diary • Company information • Industry, employees • Fleet information • Configuration, ownership, GVW • Information at each stop made by each vehicle • Location, time, purpose • Type, amount and value of goods carried / services performed

  5. Weekday Vehicle Trips 12%

  6. Weekday Vehicle Trips

  7. Impact of Commercial Vehicles • Higher value of time • Travel concentrated in some areas • Central Business District • Industrial areas • Commercial areas • Increased influence in many factors • Emissions • Congestion and vehicle flow • Pavement design

  8. Commercial Fleet Medium Light Heavy Percentages of vehicle trips

  9. Stop Purpose

  10. Tour-based Framework • Originated in personal models • Considers tours rather than individual trips • Uses additional information for decisions • Previous stop locations • Location of establishment (home base) • Simulates each trip as tour progresses • Similarities to commercial movement • A number of clients scattered through city • Efficient businesses will service them in tours

  17. Goods / Service Client Return to Establishment Client Other Client Client Establishment Lunch

  18. Trip Purposes • Goods • Pick up goods • Drop off goods • Pick up and drop off goods • Service • Perform service • Pick up supplies for performing service

  19. Trip Purposes • Other • Vehicle repair or fueling • Driver’s personal stop (e.g. meal, snack, coffee, toilet, personal business) • Stop for indirect business purpose (e.g. bank) • Return • Return to establishment • Last stop of a tour

  20. Trip Purposes

  21. High trip volume by coordinated fleet A few specific generators Difficult to survey Less demand-sensitive (more typically a set route or coverage area) Outside the scope of this model; a simpler (e.g. gravity) treatment Fleet Allocators

  22. Fleet Allocators • Mail and courier • Garbage and recycling • City parks and road maintenance • Newspaper and flyer delivery ~30%

  31. Tour Generation • Regression model • Based on zonal information • Population • Employment by industry • Accessibility factor • Generates tours, not trips • Policy-sensitive: Responds to travel conditions (accessibility)

  43. Model Features • All levels feed into each other • Whole model policy sensitive • Truck routes for medium and heavy vehicles • Calgary law: Medium and heavy vehicles must travel on truck routes whenever possible (minimize travel off truck routes)

  48. Model Operation • Trips generated one at a time in microsimulation module • Microsimulation to get trip tables • Java program external to EMME/2 • EMME/2 interface • Reads data from main model database • Generates tours in Java microsimulation (Monte Carlo) • Trip table from microsimulation brought back into EMME/2; assigned to become volumes on links
