Some drivers and traffic engineers believe that making streets wider will effectively provide for more cars and make traffic move more efficiently. Learn more here.
CityLab University: Induced Demand
Benjamin Schneider Sep 6, 2018
When traffic-clogged highways are expanded, new drivers quickly materialize to fill them. What gives? Here’s how “induced demand” works.
Two Key Points:
- In urbanism, “induced demand” refers to the idea that increasing roadway capacity encourages more people to drive, thus failing to improve congestion.
- Since the concept was introduced in the 1960s, numerous academic studies have demonstrated the existence of ID.
We’ve hit peak car. People are complaining about traffic, and lack of parking in Asbury Park and in cities all over the US. Building wider roads was never a good idea (induced demand), and it isn’t feasible or economically a great idea to build more parking (Cities are eliminating parking.) Maybe car culture in the US is about to change.

The idea of the open road evokes these intertwined meanings: The freedom to use it should be free. Residential street parking should be free. Traffic lanes should be free. Stretches of public curb dedicated to private driveways? Those should be free, too.
In other ways, the government has heavily subsidized driving, or hidden the reality of who pays for it in places no one sees. Local laws require off-street parking from businesses and housing developers, who pass on the construction cost of it to tenants and customers who may not drive at all.
