Q. Do you have to move into the intersection in order to trigger a green left-hand turn arrow on Utica Ridge Road? — Carol

A. We contacted the city of Davenport regarding your question. Gary Statz, city traffic engineer, responded:

"In order to activate the turn arrows for Utica Ridge traffic turning left onto 53rd Street, there needs to be at least three vehicles waiting in the left-turn lane at the beginning of that signal phase. It's not efficient to stop oncoming traffic for fewer than three vehicles when turning traffic would probably have a chance to turn left later in the same cycle.

"Your question asked about pulling up into the intersection and we have seen problems with drivers not pulling up far enough to trigger the signals to change for southbound Utica Ridge. We have 20-foot long detector loops that begin 10 feet back from the edge line of 53rd Street, but we have noticed traffic waiting back behind the loops and thus occasionally being undetected by the traffic controller. We're not sure why drivers are waiting more than 30 feet back from the intersection, but it might be because they don't want to block the area between the sidewalk ramps, even though there isn’t a crosswalk painted there. To help with that problem, we will be sawing extra detector loops into the pavement just behind the existing loops so that everyone will be detected. It won't change the turn arrow situation, but at least everyone will get detected."

Q. I have noticed since baseball season has begun cars are parking on the boulevard at Emeis Park. At times, there are 15 to 20 cars parked there. There are signs indicating "No Parking On Boulevard." Who would enforce the no parking? — Pauline

A. We contacted the Davenport Police Department regarding your question. Lt. Shawn Voigts, traffic safety bureau, responded:

"The police department enforces the parking in that area. Please have your reader call 911 when they see violations. A patrol squad will respond to complaints. I have alerted the afternoon shift commander and the afternoon traffic bureau shift to check for violations as call load and time permits."

Q. Now that construction season has returned, we have noticed an increase of those short flags of many different colors. Red, orange, blue, yellow etc. What does the different colors represent? — Paul, Rapids City
