Induced demand is a result of transportation being a convenience choice. Investing in a particular mode (cars, buses, bikes, etc) makes that mode more convenient and hence people tend to use it more. Demand for that mode of transportation has been "induced" by the perceived increase in convenience (safety, comfort, travel time, cost, etc).
Building additional facilities for automobiles will result in increased use by automobiles and, eventually, congestion. Thr best investments to reduce congestion are multimodal transit networks and walkable communities. Anything else is throwing good money after bad.
