As more and more cities, most recently Houston, urge its citizens to carpool to help with congestion, accidents and pollution, we decided to sit down with a MarketScale Transportation Podcast frequenter, Gareth Dennis of Permanent Rail Engineering, to get his take on this worldwide trend. Gareth, an engineer and writer, joined us to talk about the growth of active travel (and what that means), how public transit is evolving, and how the UK compares to the US in terms of transit and carpooling.
