Future Conditions Update
- Scope:
- Travel demand forecasting/traffic volume projections
- INTEGRATION modelling
- Operations analysis
- Based on final Ottawa TMP (Sept. 2003)
- Supersedes previous Traffic Operations Report - Future Conditions (Oct. 30, 2002)
Travel Demand Forecasting
- City of Ottawa/TRANS EMME/2 model
- TMP population and employment
- TMP 30% transit mode split
- p.m. peak hour
- Model runs used for volume projections:
- 2001 base year (existing conditions)
- 2021 horizon, TMP road network improvements; no Highway 417 improvements
Increases in demand caused by:
- change in modelling process
- use of 1996 travel survey instead of 1986 survey
- adjustments to work trips to account for increased labour force participation between 1995 and 2021
- adjustments to account for commercial activity (trips not captured in survey and heavy truck counts)
- higher community to community trip making in 2003 TMP
Decrease in demand caused by:
- Change in overall transit target from 20% to 30%
Results
- No existing screenline capacity deficiencies
- A capacity deficiency (equivalent to 1 lane per direction) will exist on Highway 417 from Highway 416 to Innes Road by 2021
- Adding capacity to Highway 417 attracts trips from City streets
- Minor benefit to Highway 417 from OTC and/or Interprovincial bridges
- Overall network benefits more significant than Highway 417 benefits
- Despite implementation of all transportation upgrades contained in the 2003 TMP, including realization of transit mode share targets, there is still a need to consider improvements to the Queensway

Basic Lane Needs - Eastbound
- 2011
- 3 lanes from 416 to Pinecrest
- 4 lanes from Pinecrest to Kent
- 3 lanes from Kent to Metcalfe
- 4 lanes from Metcalfe to 174
- 3 lanes from 174 to Walkley
- 2021
- 4 lanes from 416 to 174 excluding Kent to Metcalfe (3 lanes)
- 3 lanes from 174 to east limits
Basic Lane Needs - Westbound
- 2011
- 3 lanes from Hunt Club Interchange to 174
- 4 lanes from 174 to Pinecrest
- 3 lanes Pinecrest to 416
- 2021
- 4 lanes extended to Richmond
Auxiliary Lanes
- In addition to the basic lanes, auxiliary lanes will be required
at various locations to improve operations
(hence there may be greater than 4 lanes/direction in some areas between interchanges)
Note: Auxiliary lanes connect ramps between adjacent interchanges, and are used particularly where interchanges are spaced close to each other. These lanes are not continuous throughout the study area.
Summary
- The update of the traffic report did not significantly change future traffic forecasts for the Queensway.
- Despite overall transit targets being achieved, and all upgrades to transportation facilities described in the 2003 TMP being implemented, capacity deficiencies on the Queensway will still be realized resulting in increased congestion, mobility and safety concerns.
High Occupancy Vehicle Study (HOV)
Results
Although a demand for HOV lanes can be demonstrated, operational and safety concerns associated with the Queensway corridor within the study limits eliminated HOV lanes from further consideration.

EA for deck replacements
Key Plan
"Thin Slab" EA
- Significant money spent to keep bridges operating
- Separate EA for bridges to commence soon with a 6 month completion timeframe
- Conventional and Rapid Replacement Technologies (RRT) to be considered
Evaluation Methodology
(Details on methodology are contained in Volume 1of the Preliminary Alternatives Report that was distributed in advance of the meeting.)
Preliminary Alternatives Report was prepared and outlines:
- Identified Problems and Opportunities
- Assessment and Evaluation Methodology
- Alternatives to the Undertaking
- Alternative Methods
- Long List and Short List of Alternatives
Evaluation Principles
- Comprehensive
- Understandable
- Traceable
- Replicable
- Participatory
Evaluation Methodology
- Use both Qualitative (reasoned argument) and Quantitative (arithmetic) with emphasis on quantitative method
- Quantitative method - "Weighted Additive, Multi-attribute Trade-off
Method" includes:
- Level of importance of each factor/sub-factor (weight)
- Magnitude of the impact/benefit (score)
- Scores are derived from function forms
- Sensitivity testing carried out to test rigour of preferred alternative
- Evaluation carried out by multi-disciplinary team
PAC Input
The project team is looking for input from PAC members in two ways:
- Comments on the evaluation factors to be applied (Table 5); and
- Input into factor weights to be used in sensitivity testing (handouts)
Note: The evaluation is being carried out at the end of April, so PAC input is required by April 19, 2004.
Alternatives - Mainline and Interchanges
See Preliminary Alternatives Report, Volume 2 of 2 – Alternative Plans
Other Business
HOV Study Update
HOV Alternatives considered:
- Major widening - widen throughout to provide HOV lane with full geometric cross section
- Strategic widening - widen to create basic 8 lanes from 416 to 174, and 6 lanes from 174 to east limit with one lane/direction for HOV
HOV Implementation Considerations
- Limits
- EB – continue lane from west and terminate east of St. Laurent
- WB – either east or west of 174 I/C to connect to east of Richmond Road
- Separated vs. Non-Separated
- Separated preferred but would require extensive widening and property acquisition throughout the corridor
- Enforcement
- Given site constraints, desirable enforcement areas not possible
- Violations up to 75% reported in other jurisdictions
- Access/Safety
- Grade separated not feasible with corridor constraints
- Proximity of interchanges and congestion on GPL’s significantly degrade HOV efficiency and safety on the whole facility
