Once again the Texas Transportation Institute (TTI) published its annual Urban Mobility Report (UMR), and once again I feel obliged to warn planners that it is based on faulty assumptions and biased analysis methods. This is not to deny that traffic congestion is a significant problem, but the UMR significantly exaggerates its importance compared with other transport costs and exaggerates roadway expansion benefits.
