In some places, requests like this are referred to an administrative unit that makes decisions about such issues. That raises a few questions for me.

First, I am assuming that the intersection is under city jurisdiction. Is that correct?

Next, if it is city jurisdiction, does anybody know what person or entity in city government handles such issues? Does a comment like this get referred to that person or entity automatically, or is there some formal process to petition for an issue to be taken up?

Any information about the process would be appreciated.

Please see my earlier comment. Any information about the process would be appreciated.

Thank you for contacting the City of Ann Arbor regarding your concerns about pavement markings at this intersection.
City staff have reviewed the intersection design and are confident that the 150 feet of dual receiving lanes south of the intersection are still an appropriate design.

Your request has been acknowledged and/or addressed to the best of staff's ability. A more detailed description of action taken by staff, if available, is provided in the comments above. Thank you for bringing this to our attention.

My suggestion had to do with the lane markings for the southbound lanes of Green Road north of the intersection, and it seems that city staff has evaluated the appropriateness of having two southbound lanes south of the intersection.

Two lanes south of the intersection seems like a good idea, but it does not make sense to have two southbound lanes coming straight through the intersection from the north and merging immediately after the intersection, especially since one of those lanes is also a left-turn lane. Allowing cars to proceed straight through the intersection from both of those lanes leads to unnecessary confusion for the drivers.

Notice that cars exiting the intersection southbound on Green Road can enter the intersection from three directions -- westbound on Plymouth Road, southbound on Green or eastbound on Plymouth. There is one lane from which drivers can turn left from westbound Plymouth Road into southbound Green. There is one lane from which drivers can turn right from eastbound Plymouth into southbound Green. Having two lanes south of the intersection allows some drivers to wait to make a left turn into the commercial area at the southeast corner while other drivers can pass them on the right before the two-lane section ends.

The only confusion is when cars are going straight from both lanes. Some drivers decide to use the straight-only lane to go south on Green, and others choose the lane that is also a left-turn lane. That lane then gets priority in the merge. That creates confusion about which is the right lane for going straight through the intersection from the north.

Thank you for your A2 Fix It request, #303845. Your request is important to us and will be prioritized and addressed based on the overall availability of city resources. Please note: If the nature of your request is urgent, such as water emergencies, please check http://www.a2gov.org/a2fixit for phone numbers to contact us. A2 Fix It is for non-urgent, non-emergency issues and is monitored during weekday business hours only. Your patience is appreciated.

I agree with Jim Eng. The lane that can turn left or go straight is always by far the lane with the most cars. Most people turning left go in that lane, along with a few going straight. Making that a left-turn-only lane will reduce the number of cars in that lane somewhat, more evenly balancing the cars backing up at that intersection.
