Six Mile Corridor-Mitigative solutions
Recommendations were examined in terms of approximate monetary costs to implement over a measure of anticipated impact (or benefit) with regards to the three grouped objectives listed below as determined by the public engagement process.
Impact score-were calculated as follows:
- Points (out of 5) for improvement to traffic flow during peak periods;
- Points (out of 5) for traffic calming impact; and,
- Points (out of 5) for improvement to non-vehicle transportation mode impact.
The lowest Cost/ Impact values therefore represent best returns from a cost perspective. These values are intended to be used as general guidance and also for comparative analysis.
