Evaluating the Alternatives
Each alternative was evaluated across seven different accounts to identify its range of benefits and impacts, using planning tools such as transportation demand forecasting and financial models, and qualitative assessments.
For each account, we compared each alternative against a "business as usual" scenario that considers only anticipated transit improvements according to past trends and no rapid transit in the corridor. Several criteria within each account were considered. We then scored each alternative on a five-point scale for each criterion. The results were summarized into a single score for each alternative for that account (shown above).
No weighting was applied, but we emphasized criteria that helped to differentiate between alternatives.
This is a summary of the preliminary evaluation results. We want your input to ensure that we have captured the full range of benefits and impacts. Using your input, we will finalize the results and present them to decision makers later this year. The fullness of a circle shows how the alternative performed in an account, ranging from an empty circle (very poor) to a full circle (very good).

Preliminary Conclusions and Next Steps
- None of the alternatives have been excluded at this point.
- BRT does not have sufficient capacity to meet projected demand over the long-term.
- Option B of the RRT Alternatives, which extends the Millennium Line and serves Great Northern Way, attracts more riders and is more promising than Option A.
- Options A and B of the LRT Alternatives still need more work to determine which is stronger.
- Before the evaluation is finalized, the design concepts will be optimized and as the design assumptions change, the evaluation will be updated. For example, BRT and LRT have street impacts that affect other road users; refining designs may help reduce some of these impacts.
- Refinements to population, employment and student growth assumptions may be made during further technical analysis, which may affect ridership forecasts and evaluation results.
- Alternatives generating the most benefits also tend to cost the most, and the trade-offs between benefits and costs need to be considered.
Public consultation is underway to help us finalize the evaluation results.
