A Ho-Ho-Kus resident, frustrated with traffic patterns in her neighborhood, hired an engineering firm to conduct a $600 traffic study.

The firm installed cables on Powderhorn Road that measure traffic speeds, volume and vehicle weight, according to a report from NorthJersey.com.

But police say taking matters into your own hands, like what resident Donna Cioffi did, is illegal.

Cioffi was given a letter by the borough Monday demanding she has the cables removed within 24 hours, the report said.

Cioffi says the traffic volume on her road exceeds the number of vehicles municipal officials claim travel on the road daily, the report said.

Powderhorn Road is a popular shortcut for motorists navigating to Country Road 502, but it was never intended to be a through street, Cioffi told CBS 2 in New York.

Cioffi told the news station the town has installed speed bumps and stop signs, but that these are only "Band-Aid" solutions.
