Traffic congestion is one of the most significant challenges facing our cities. One obvious solution to traffic congestion, caused mostly by workers commuting to jobs in the city centre during peak hours, might appear to be building more, or bigger, roads. But a less obvious answer, and potentially a more cost-effective one, might be to increase flexible working arrangements. Our research has looked into ways to ease congestion by reducing the need for travel in congested areas in the first place. It shows city workers definitely have an appetite for flexible work hours and practices.
