TW: We all know this but it is always good for someone to put some data behind the hypothesis. So given the economy, one should exercise extra vigilance whilst breaking the speed laws...
From Paul Kedrosky's blog:
"Municipalities have revenue motives for enforcing traffic laws in addition to public safety motives because many traffic offenses are punished via fines and the issuing municipality often retains the revenue. Anecdotal evidence supports this revenue motive. We empirically test the revenue motive using a panel of annual data for North Carolina counties from 1990 to 2003. We find that significantly more tickets are issued in the year following a decline in revenue but that the issuance of traffic tickets does not decline in years following revenue increases. Elasticity estimates reveal that a 10 percent decrease in negative revenue growth results in a 6.4 percent increase in the growth rate of traffic tickets. Our results suggest that tickets are used as a revenue generation tool rather than solely a means to increase public safety"
