The case study, conducted in Baltimore, Maryland, says that "Bike lanes create the most indirect and induced jobs.
From the report: "$1 million in spending on pedestrian projects creates 11.3 jobs. Six of these jobs are directly created in the construction and engineering industries.An additional 2.2 jobs are indirectly created in industries such as concrete manufacturing and sign manufacturing. Further, 3.1 jobs in retail, healthcare, and food services are created through the induced effect. Thus a total of 11.3 jobs result from the initial $1 million pedestrian project."
