Photo Enforcement Vans More Effective Than Signs, Police Cars, U. of I. Study SaysAbstract:
Police vans equipped with radar cameras to enforce the speed limit are the best available tool to force motorists to slow down in construction zones, according to a new study by University of Illinois researchers. The Illinois State Police photo vans are capable of identifying scores of speeding scofflaws across multiple lanes of traffic in only a few minutes, ringing up minimum $375 speeding tickets that are sent in the mail for the work-zone violations. According to law-enforcement officials, this process is much more efficient and safer for police officers than pulling over individual speeders as traffic rushes past.
