Crawford, Bunte, Brammeier (CBB) traffic engineer Lee Cannon studied the intersection of Manchester Road and Big Bend Boulevard, as well as Martini Drive, pertaining to the proposed relocation of the QuicTrip to the intersection. QuikTrip paid for the study.
He submitted the assessment to QuikTrip. A copy also went to the City of Maplewood, and Patch got a copy from the city.
Access to the station is proposed to be via one driveway on Manchester Road, via Martini Drive and two driveways on Big Bend Boulevard, near current curb cuts. The southern curb cut on Big Bend would be right-in only. QuikTrip would also donate right-of-way and widen southbound Big Bend to create a separate right-turn lane.
(Stay up to date. Get the Maplewood-Brentwood Patch newsletter.)
The focus of the analysis was the morning commuter/school arrival, afternoon school dismissal and afternoon commuter peak hours of a typical weekday.
(Editor's note: the original report was written in paragraphs. It's presented here in bullet points. In most instances the wording is CBB's.)
Traffic counts and observations
- The study was made in early May 2012
- Traffic volumes were very high at the signalized intersection, 3,500 to 4,100 vehicles per hour during the three peak hours.
- Daily volume at the intersection estimated at 35,000, which is relatively high
- Current queuing on both roads will likely continue to block access to and from the site during peak hours.
Martini Drive
- Used daily by passenger cars and school busses for access to Maplewood Richmond Heights School
- Students also access the school via the west sidewalk along Martini
- There was not a large number of student walkers on the Martini sidewalk
- 25 in the morning
- 55 in the afternoon dismissal hour
- 15 in the commuter peak hour
- Most students use the crosswalks at the intersection, a few crossed Manchester at Martini or Jack in the Box
Existing store traffic (in Feb. 2012)
- 485 total trips in the commuter/school arrival peak hour
- 395 afternoon in the afternoon/school dismissal peak hour
Proposed store traffic
- 16 pumps, 4 more than the existing store
- Traffic expected to increase by 15 to 20 percent over the current store, based on QuikTrip experience from similar locations
- Trips are expected to increase by 100 cars in the commuter/school arrival peak hour
- Trips are expected to increase by 80 cars in the afternoon school dismissal and afternoon commuter peak hours
Intersection traffic at the proposed new location
- Expected to stay the same
- Traffic is expected to increase north of the site on Big Bend and east and west of the site on Manchester by 5 to 30 cars per hour in each direction
- Traffic south of Big Bend on Manchester is expected to decrease by 55 to 75 cars per hour in each direction
- With respect to the existing traffic levels, the additional trips will not be noticed
- The added traffic levels would be half or less of typical daily fluctuations estimated at a conservatively low 5 percent
- This assessment did not address traffic impact from the approved CVS pharmacy or the potential future use of the old QuikTrip site
The levels of congestion are not expected to change noticeably at the Manchester/Big Bend intersection.
- The addition of a southbound right-turn lane on Big Bend will lesson congestion somewhat at that point
Turning movements will increase
- Expect Martini to carry approximately one-third of total site trips
- Based on the access configuration which limits peak hour left-turns out of Martini and restricts the south drive on Manchester to right-in only, Martini will be used more for entering trips (45-60 percent) than exiting trips (20 percent or less of the total)
Pedestrian safety is key for all stakeholders
- The existing sidewalk on the west side of Martini provides a safe location for pedestrians walking between the MRH and Manchester to the east or the west
- Provides unobstructed access to Manchester Road west and the westbound bus stop on the north side.
- Provides safe access to Manchester Road east and Big Bend Boulevard south via crosswalks at the signal
Crash history involving pedestrians
- Maplewood Police Lt. Mark Griffin indicated there have been no pedestrian fatalities in his 27-year tenure
- There have a been a few incidents resulting from students jaywalking across Manchester Road
- A student crossing guard is now posted to encourage students to cross legally
We (CBB) do not believe the QuikTrip store would pose a significantly greater danger to pedestrians (primarily focused on school children).
- The existing and proposed sidewalks and marked crosswalks provide reasonably safe accommodations for pedestrians
- The proposed improvements would improve sight-lines at the intersection
- Students on sidewalks near the Shell station, Jack in a Box and White Castle are on the far side of very high traffic highways. Their exposure to traffic on those sidewalks is higher there than it would be walking alongside or to or from the proposed QuikTrip.
- Most of the traffic that will access QuikTrip is already traveling to and from the site south of Manchester Road.
- An adequate sidewalk on the west side of Martini Drive is a safe place for students to walk to school
Cut-through traffic from Big Bend to Martini through the north end of QuikTrip should be discouraged.
The report also had safety recommendations for when construction takes place.

Thanks for posting this. I have a few quick comments:
* The study was performed in early May. There was no active business at the SE corner of the intersection (soon to be CVS) and demolition had not begun yet so no demolition/construction trucks to consider in the traffic volume estimates.
*"Current queuing on both roads will likely continue to block access to and from the site during peak hours." I agree and that is a big problem for this intersection. It will drive traffic onto Martini. Improper use of left hand turn lanes also not addressed. Admittedly, this is not for QT to address but will be exacerbated by the existing plan.
They expect Martini which is no more than an alley to carry one third of total site trips. This is a problem because the South end of Martini is inadequate for anything but a right hand turn onto Manchester. The Rannells light at the North end of Martini already backs up from just 7-11 and residential use. What are the rest of the customers going to do? Cut through the school campus along Lohmeyer?
Still shows entrance from Northbound Big Bend to be inadequate and frankly unusable during peak hours.
Good information and it shows that QT needs to work with the City of Maplewood, the MRH School Board, and STL County if they want to make this a viable location. Currently, I do not see a reasonable way to locate a major convenience store and gas station there.

Thanks Doug! During the meeting last week Mr. Cannon mentioned having numbers on the increase in traffic on Martini Drive, but I don't see that in your summary. I think a lot of us see that as a big question, and no answer from QT. How much more traffic will Martini see at the corner, and how much more down the entire alley as motorists get fed up with the Big Bend North exit?

Ian - Increased traffic on Martini wasn't mentioned specifically, but taking the projected site numbers of 585 in the morning rush hour and 475 in the school dismissal peak hour, and dividing by a third (Martini is expected to carry 1/3 of total site trips), you get 195 in the am peak hour and 158 in the pm peak hour on Martini.

Thank you Doug for summarizing the key points of their report. QT has not given us any indication of the northbound Martini volume, a glaring oversight. I'd like to know what is meant by "trips are expected to increase" in the proposed store traffic section. Do they mean just 100 cars going onto the property at peak hour? If yes I am not convinced that is true. 52 parking spaces and 16 pumps. Just seems if a typical stop there is 10-15 minutes they could get a lot more than 100 visits drawn from 3 to 4 thousand cars. They also are remiss not including a projection for increase due to CVS' presence. And why would Lt Griffin not make mention of the fact that students had been bumped there. The police department might consider restating their position as TP has said that the city was asked to enlist police help with how to address safety at the intersection after some children were bumped there. Or perhaps Lt Griffin was misquoted in the report, did not know of the incidents or was misinformed that the bumped students were all jaywalkers. I'd like to hear more from the Lt on this.

I just now read Doug's clarification. Thanks again Doug! So wow that's a lot of cars and even more than I expected on Martini. How many will go north is still at question. Even if it is only 25 of the 195 or 158 it's a problem as I see it.

To anyone who signed the petition on QT's counter who now is reconsidering after having learned more about the development....please sign my petition at change.org. Put in the comment section that you previously signed the QT "for it" petition. I will be sure to have your signature removed from QT's "for it" petition. I have a copy of their petition and have already readjusted their numbers as they included over 76 non Maplewood or RH residents. I can remove your name as well if you like. It won't mean you just oppose QT but that you oppose the plan as written.

So the study paid for by Quik Trip found in QT's favor. Shocking.
Is anyone really taking this seriously?

Not sure if anyone has thought about this, but with this proposed QT plan, the CVS, White Castle and the Shell station, there is going to be probably close to 150 parking spots at this intersection. To me that seems like a few to many for a "walkable" community. I am still confused as to why QT thinks they are creating a "destination". It's a gas station, people will get gas, bottle of soda, beer and a snack or two and that is it. I am not going to have dinner at QT when I can have the best cheesesteak in town at the Post.

Jason Meyers, unfortunately it was enough for the Maplewood P&Z board. I was quite surprised they even voted after the traffic engineer told them he had to get back with them on the numbers of cars that will use Martini....he did not have that info off the top of his head, promised to give it to them later and they still voted. We must keep getting the word out so that the city council does not act with equal irresponsibility.

This was the first time I had been to a P&Z meeting (really a civic meeting of any kind) and I could tell how this thing was going to go within the 1st minute of questions from the board. I am convinced those 'yes' votes were there before anyone walked in the room. Their questions amounted to how great the new sight lines were going to be and whether or not their would be a pole sign. The only intelligent questions/discussion came from the No votes. Imagine that. And then the obvious 'swing' vote abstains, with one member absent. Totally irresponsible on an issue so obviously important to the people and shape of MRH. I hold your hope that the city council are more professional and diligent.

Here's a possible solution. Put a barrier on Martini to block North Bound traffic at the north end of the property. Create pedestrian walkway with fence along Martini behind QB. Create a wide pedestrian walkway from Martini to Big Bend on the north side of the property (with trees and landscaping) AND add a pedestrian controlled light at the end of the walkway (between Rannel and Manchester). Have a crossing guard there during peak times. Then make Martini, Florent and Gethard one way south to the new parking lots. Might also want to throw in widening Martini.

Nancy, I sure hope city council has the creative desire to make it work and will consider ideas like yours. But just in case they prefer to approve it as is, if you are a Maplewood or Richmond Heights resident I invite you to sign our petition. With it I hope to drive the city toward insisting upon creative ideas like yours. Petition link is http://www.change.org/petitions/city-council-deny-approval-of-the-quick-trip-relocation-proposal

Study was performed in May, during the daytime hours I guess?; and only seems to take in to account daytime school activities; what about when sports or other nighttime school events happen and the street of Martini is lined with parked cars?

If its been deemed a dangerous corner-why would parent permit kids to cross the street as it exists today?If it isnt "safe" then why are concerned parents only now bei fussy?
Jeff Kiefer
11:47 pm on Wednesday, July 11, 2012
Parents whose children walk to school and pass the intersection have been "fussy" to use your words already as their children have been bumped crossing responsibly with the light. They brought it to the attention of the school who implemented crossing guards. Therefore Increasing traffic flow here especially along Martini understandably creates more "fussiness". While the intersection is of concern I must reiterate again that increased traffic north along Martini and thus around the campus will create traffic hazards even for the parents who, like me, drop their child off via Rannals and Lohmeyer.

The projected volume increase is directly proportional to the number of additional pumps. This indicates that the current location is working at maximum capacity, while serving only north/south traffic.
Since they're at capacity, during peak time traffic turning in and out of the facility almost certainly includes people driving in and out without stopping, after discovering there are no available pumps or parking spaces. This means that the number actually served underestimates the number driving in and out.
Since the new location will add east/west traffic to north/south, the number of people driving in and out without stopping to buy gas (due to overcrowding) would be far greater. Thus, I have to believe raw traffic flow is being seriously underestimated.
An additional factor is that these non-served persons are going to be irritated and angry, and their may well be careless, irresponsible and dangerous.
