Let's put the question in context.
It really depends on how you define a strategy. Different countries have different approaches to how they support public transit, be it through funding policies or other mechanisms. So that makes it really tough to say which countries have a strategy and which ones don't.
However, a core element of a strategy could be better alignment between infrastructure investments in new subway lines or light rail systems, for instance, and land use planning. That is the most important principle. Ensuring that investments are as effective as possible is key, so it's important to target the investment in the area that will deliver the best return and ridership. The right investment formula is also necessary to ensure adequate and ongoing funding in the context of a multi-level government partnership.
Finally, a research and development program to help develop state-of-the-art technology would be important, in addition to ridership incentives. That could take the form of an excise tax exemption for employers who want to give their employees a choice between a parking spot and a monthly transit pass, for example.
