Data generated by travel modes can inform planners and regulators in improving the transportation system, but private mobility companies often restrict their access for concerns about privacy and competition.
Transportation system performance is often evaluated using congestion intensity indicators, which favor automobile-dependency and sprawl. Strategic planning requires more comprehensive and multi-modal indicators which measure congestion costs.
The best solution to many transportation problems is to improve transport system diversity so travelers can choose the best option for each trip. This requires more comprehensive and multi-modal planning. Not everybody is ready.
A new study claims that public transit does not reduce traffic congestion. It is a good example of how not to evaluate this impact. When measured correctly, high quality transit is found to reduce congestion and increase transport system efficiency.

It is time to find better solutions to congestion problems. This requires more comprehensive evaluation in order to identify win-win solutions: the congestion reduction strategies that help achieve other planning objectives.
Critics claim that public transit projects consistently exceed their budget projections and fail to meet ridership targets, based on old research. New analysis indicates that recent transit services generally perform better than predicted.
This column expands on issues raised in a previous Planetizen blog, "Mythbusting: Exposing Half-Truths That Support Automobile Dependency," which examined criticisms of cycling facility investments and justifications for automobile-oriented planning.
Some commentators recently expressed outraged that governments spend money on cycling facilities. Their arguments are largely wrong, I’ll call them "half-truths" to be charitable, presented with great certitude and self-righteous anger.
PolitiFact holds politicians accountable for their claims, but how accountable is PolitiFact? Not very. It inaccurately answered a simple planning question, and was unwilling to clarify or correct its false judgment.
Contrary to popular assumptions, large, transit-oriented cities have lower crime rates than smaller, automobile-oriented cities. Jane Jacobs was right! This column discusses this phenomenon and its implications for transport and land use planning.
