Commercial Vehicle Movements Vehicles operated for commercial purposes As opposed to household, personal movements Includes ‘non-commercial’ non-household purposes (government, not-for-profit) Comprise 10-15% of total urban traffic
9
Some Examples Commercial Hauling freight for a company Service workers visiting clients Sales meetings Mail Delivering parcels Personal Travel to work Travel to school Shopping Leisure trips Social visits
10
Data 2001 Commercial Movement Study All commercial movements Not just freight Not just trucks 3,100 establishments in Calgary 4,300 establishments in Edmonton 24 hour stop diary Firmographics Employment structure Vehicle fleet

Tour-based Micro-simulation Considers tours rather than individual trips Micro-simulation of each tour Uses additional information for decisions Full-tour conditions Location of establishment (tour-base) Work-shift influences Simulates each trip as tour progresses Closer to reality A number of clients scattered throughout city Efficient businesses will service them in tours

Operation PTM (EMME/2) Commercial Movements Model (micro-simulation) Updated travel times Run of modelRun of process Updated commercial vehicle trip tables Updated personal trip tables Base Information Re-assignment of trip tables
34
Model network loading of light vehicle flows
35
Model network loading of heavy vehicle flows less in CBD; more in industrial areas little on non- truck routes
36
Results Being used for practical policy analysis A number of demonstration policy tests considered here Five scenarios: Base case Increased cost of travel (per km) Increased travel time Removed truck route restrictions Instituted large toll for stops in CBD

41
Calgary Conclusions Tour-based micro-simulation approach used here Successful Provides direct representation of trip-chaining impacts Includes service delivery Well beyond ‘freight only’ and ‘large heavy vehicle’ limitations Useful planning tool for Including commercial movements and their impacts on system Assessing impacts of transportation policy and infrastructure development on commercial sectors
