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, real estate forecasting, financial models and qualitative assessments.
For each account, we compared each alternative against a "business as usual" scenario that assumes significant transit improvements according to recent trends and the South of Fraser Area Transit Plan, but no rapid transit improvements. Several criteria within each account were considered. Within each account, each alternative was rated 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 table summarizes the preliminary evaluation results. The fullness of a circle shows how the alternative performed in an account compared to "business as usual." This ranges from an empty circle (worse) to a full circle (better). 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.
Preliminary Conclusions and Next Steps
- None of the 10 alternatives have been excluded at this point.
- The alternatives differ by extent and technology; the preliminary results provide an indication of the incremental costs, impacts and benefits of these differences.
- Alternatives with rapid transit on Fraser Highway have many more transportation benefits (attract more riders and save them more time).
- RRT 1 is the fastest and saves the most travel time along the Fraser Highway corridor, but at high cost.
- BRT and LRT along Fraser Highway provide similar travel time savings and generate similar ridership.
- Alternatives with rapid transit south between Newton and White Rock cost more and have more construction challenges and potential environmental risks because they cross the floodplain twice but don’t generate many more benefits.
- The preliminary designs will be updated based on public input and further technical work, and the evaluation would be updated accordingly.
- Refinements to population and employment growth assumptions may be made during further technical analysis, which may affect ridership forecasts and evaluation results.
