Multiclass Road Assignment Tool
Expanded Version of Toll and Transit Background Road Assignment
4Slide5
Tool Details
Based on the previously established toll-attribute road assignment with transit background tool.
Functionality now exists to assign more than just the ‘auto’ mode.XTMF Module developed to facilitate use.
Applied and tested on two projects thus far.
5Slide6
VDF Updating
Work conducted in Mississauga
6Slide7
Work with Peel Region and Mississauga
It was discovered that some roads within Peel region did not have the appropriate functional classification.
Through meeting and consultation, a heuristic was developed and employed to update the VDFs of critical roadways.Heuristic: examination of adjacent land use, zoning/development maps and ‘best-practices’.Further updating?
A more complete picture in Peel?
Other regions?
7Slide8
Truck Route Restrictions
Where are we now?
8Slide9
Open Questions
It is the understanding of TMG that up-to-date truck restrictions exist in all regions except for:Halton,
Peel Region except Mississauga.Are the regions satisfied with the current truck restrictions found in the base network?
9Slide10
HOV Network Coding
Lessons Learned
10Slide11
HOV Lane Coding
All freeway HOV lanes are coded into the base network.HOV lane functionality requires an alteration of usual auto assignment:
Low-occupancy vehicles (LOV), must be denoted by a mode in EMME other than the auto mode ‘c’.Implemented to prevent auto mode dominance on road network links designated for other subclasses.
HOV lane validation conducted.
Validation further served to test multiclass road assignment.
