artificially setting limits like that is a poor solution, especially when you're depending on police enforcement to ensure compliance. a better solution is narrowing lanes (to 9-10 ft), and possibly installing bollards everywhere, because that internalizes the costs of collision (car gets wrecked and you get hurt in addition to pedestrians), so drivers naturally self-regulate driving behavior for safety (rather than the secondary measure, speed). you also don't need an external police force and it's attendant costs, both financially and societally, for enforcement.
