Quality of Life
The Institute of Transport Studies at Monash University, Australia published a study linking quality of life and public health to transport systems and overall user happiness.
A team of scholars from Belgium correlated shorter, more sustainable commutes to residents of Flanders and the Brussels capital region–the most robust performers in the Belgian economy. Residents of Wallonia, a historically industrial region, endure longer, less sustainable commutes.
Chinese and Korean scholars found that the success of integrated rail and concurrent mixed-use land development correlate highly with density. Patrons and residents must co-locate to new rail transit-oriented development (TOD) for it to be sustainable.
Induced Travel Demand
A recent joint report from Aalborg University, Denmark and The Institute for Transport Economics, Norway shows that adding roadway capacity induces travel demand, actually increasing traffic. The report finds that it is common for planners to neglect this impact in the long run when planning traffic forecast models.
