Preliminary Alternatives Report: Table 3

Does not address existing and future traffic needs

Does not improve mobility or ease congestion

Increased collision potential with increased traffic demand

Reduced efficiency with Do Nothing alternative

Potential to partially address existing and future corridor capacity requirements

May improve mobility or ease congestion (dependant on modal split achieved)

Minor reduction in collision potential

Should be considered as part of area-wide transportation solution

Provides travel choice, efficiency and effectiveness

Potential to partially address existing and future corridor capacity requirements

Limited opportunity to improve mobility and ease congestion

Marginal reduction in collision potential

Should be considered as part of area-wide transportation solution

Provides travel efficiency and effectiveness

Most effectively addresses existing and future corridor capacity requirements

Improves mobility and eases congestion throughout the study section

Significant reduction in collision potential

Promotes more effective and efficient travel

Addresses majority of existing and future corridor capacity requirements

Improves mobility and eases congestion where strategic widening improvements made

Reduction in collision potential

Promotes more effective and efficient travel

High potential to fully address existing and future corridor capacity requirements

Improves mobility and eases congestion throughout the study section

Reduction in collision potential

Promotes more effective and efficient travel

Potential to address existing and future corridor capacity requirements where highway widened for HOV lanes and HOV lane fully utilized

Improves mobility reduces congestion where highway widened for HOV lanes and HOV lane fully utilized

Increased collision potential without buffer between HOV and GP Lanes. Speed differential between HOV and GP lanes creates increased potential for more severe collisions

Promotes more effective, efficient travel

No impacts except reduction in air quality with increased severity and duration of congestion

Variable impacts (dependant on nature, extent and location of transit infrastructure requirements).

Minor impacts related to removal of vegetation with the construction of commuter parking lots, queue jumping lanes and the installation of traffic management systems

Significant impacts on watercourses with wider crossings, more vegetation removed for construction, more quantity and quality control needed for runoff from impervious surfaces

Moderate impacts with wider crossings on some watercourses, some vegetation removed in areas of widening and quantity and quality control needed for runoff from impervious surfaces

Significant impacts on watercourses with wider crossings, more vegetation removed for construction, more quantity and quality control needed for runoff

Moderate impacts with wider crossings on some watercourses, some vegetation removed in areas of widening and quantity and quality control needed for runoff from impervious surfaces

Increasing delays to emergency services as a result of increasing congestion

Does not support planned growth

Variable impacts (dependant on nature, extent and location transit infrastructure requirements)

Alone, does not support planned growth

Limited social impacts related to the location and extent of any TDM measures

Alone, does not support planned growth

Potential impacts on heritage structures adjacent to corridor

Greater pavement area may result in removal of landscaping significant social impacts

Supports planned growth

Potential impacts on heritage structures adjacent to corridor in areas of widening

Greater pavement area may result in removal of/less landscaping

Supports planned growth

Potential impacts on heritage structures adjacent to corridor

Greater pavement area may result in removal of/less landscaping significant social impacts

Supports planned growth

Potential impacts on heritage structures adjacent to corridor in areas of widening

Greater pavement area may result in removal of/less landscaping

Partially supports planned growth

No property required

No support for City policies

Variable property required (dependant on nature, extent and location of transit infrastructure requirements)

Partial support for City policies

Minor property required, depending on the extent and nature of the TDM measures

Partial support for City policies

Significant property required (in excess of 300 homes, businesses, institutions, parks, etc.) for highway widening and stormwater management facilities

Not supportive of City policies

Limited property required (about 15-40 homes businesses, institutions, parks, etc. for highway widening and stormwater management facilities, depending on specific details)

Support for City policies

Significant property required (in excess of 300 homes, businesses, institutions, parks, etc.) for highway widening and stormwater management facilities

Not supportive of City policies

Limited property required (about 15 -- 40 homes businesses, institutions, parks, etc. for highway widening and stormwater management facilities, depending on specific details)

Support for City policies

Increased maintenance and associated staging costs

Variable capital cost (dependant on nature, extent and location of transit infrastructure improvements)

Low to moderate capital costs related to car pool lots, advanced traffic management systems, etc.

High capital cost related to full length widening with structure replacements, retaining walls, etc.

Moderate capital cost related to widening in areas of existing 6- lanes only

Highest capital cost of road improvement options (HOV buffer zones add to the widening requirements for GPLs)

Moderate capital cost related to widening in areas of existing 6-lanes only and conversion of GPLs to HOV lanes
