The concept of road diets circulated in Metro Manila more than a decade ago. I recall the Metro Manila Development Authority (MMDA) picked up the concept and attempted to apply it in some parts of Metro Manila. Since there are no evidence of that endeavor surviving now, then we can assume that it was a failure. There is no wonder there as I also recall the effort to be half-hearted and more to get media mileage (cheap talk or lip service) out of it. Road diets eventually evolved into the complete streets (though the literature now will state road diets as part of complete streets). That experience and similar initiatives of varying success (or failure) rates are not unique to the Metro Manila but is actually happening elsewhere including cities in countries where the complete streets have been applied more comprehensively and yet somehow found to be lacking or not as effective a solution as expected. I am sharing an article here that discusses what seems to be lacking or ‘incomplete’ as it is referred to.

Source: What’s Incomplete About Complete Streets?

Quoting from the article:

“What’s missing? First of all, even the best Complete Streets policy can’t solve the problem of fiscal scarcity. Even in a city committed to Complete Streets, street redesign must fight for public dollars with other worthy goals such as education and public safety. As a result, Indianapolis’s improvements are a drop in the bucket. The city maintains 3,400 miles of streets and roads, so its 100 miles of bike lanes affect only 3 percent of the city. Similarly, 2,000 miles of the city’s roads still lack sidewalks.

Second, the quantitative benchmarks seem to focus on sidewalks and bike lanes (Sec. 431-806), and the policy doesn’t mention traffic calming or similar policies. So if the city had a six-lane road with traffic going 60 miles per hour, the Complete Streets policy would not affect that road except to the extent necessary to build a sidewalk or a bike lane.** Thus, even the best Complete Streets policies don’t really address some of the most dangerous features of American street design.”
