The Iowa Senate is scheduled to take up a ban on automated traffic cameras Wednesday. The bill is a straightforward ban on the cameras used for red light or speed enforcement. It requires that communities using them discontinue their use before July 1st and all local ordinances about using them would be void. The Legislative Services Agency says as of the end of January, 78 traffic cameras were used by eight communities. This fiscal year it would mean those communities would lose a about $12 million in revenue. Cedar Rapids would lose $4 million, while Des Moines would lose over $3 million and Windsor Heights about $526,000. Backers say they have the votes to pass it, but its fate is still uncertain in the House.
