Some follow-ups from last week. First - Kirk was asking about the bikes yielding at Tucker to the ramp from the interstate. I got a couple more details on this -- it is somewhat unorthodox to have the bikes yield, but we have had a significant number of crashes in this area, and we have drivers trying to make an illegal U-Turn onto Tucker from this ramp. Because of those conditions, we felt that it was safer to have the bikes (who are more vulnerable) yield in this situation. Andrew Gates, MoDOT Communications
CityDriver asked about a rough patch on Chippewa. We have asked our pavement repair team to see what they can do for the rough patch. Andrew Gates, MoDOT Communications
M asked about yellow and red arrows on signal heads. According to the Manual on Uniform Traffic Control Devices (our national standards book), they are not allowed. I can't speak to why Virginia is using them. Andrew Gates, MoDOT Communications
We change between our morning rush plan and mid-day timing plan at 9 a.m., and it appears that, the transition hung up a bit -- we also had a problem with a detector at Parkway Middle School. I have shared that with our signal team to repair it. When you see issues such as this, you don't have to wait for the chat room. You can call them in to our customer service team 24/7 at 314-275-1500. Andrew Gates, MoDOT Communications
I will alert the Forestry Division of the conditions you described for NB Tucker approaching 13th St. Thanks for heads up!
It does appear we are getting "false calls" on the side street vehicle detection. When the equipment malfunctions (likely a battery dead in the wireless in-pavement sensor), it fail-safes to a constant call on the side street (rather than no call) so the signal will cycle to the side street in the event someone is actually there. We will get a crew out to repair the vehicle detection equipment. Let's see where the vehicle detection issue leads to in terms of changed progression along Hampton as also noted. This fail safe condition is providing the maximum amount of time possible to the side street that was programmed, when in a properly operating condition it would on average time out due to lack of vehicles sustaining the calls to extend time to its maximum. If it continues to appear that coordination is off after the repair, we will meet with MoDOT to review.
Follow up to earlier chat comment: the Forestry Division has dispatched someone to investigate the NB Tucker visibility issue with trees.
Last week, a Road Crew reader wrote: "A lot of subdivision side streets are uncontrolled (i.e. there is no traffic control device.) Occasionally I'll drive through an area and see that the county installed two-way stop signs. It seems to me that if an intersection changes from uncontrolled to needing traffic control devices, yield signs should be installed. As a general comment from my travels throughout the country. The yield sign seems to have fallen out of favor except for right turns and entrance/exit ramps. To my thinking, it's still a great tool that should be employed more often." ST. LOUIS COUNTY'S REPLY: St. Louis County reserves "Stop" signs for intersections that demonstrate a legitimate need for the assignment of right-of-way where a driver has to come to a complete stop and is unable to see oncoming traffic when approaching the intersection. “Yield” signs are an option by the Manual on Uniform Traffic Control Devices, as published by the Federal Highway Administration. For the most part, we choose not to use "Yield" signs in subdivisions in order to prevent unnecessary proliferation of signage on our roadway system. The vast majority of these uncontrolled intersections operate in a safe and efficient manner. David Wrone, St. Louis County
I have asked our traffic team to work with the city of St. Louis and see if we can make any improvements. Typically, we do not want to have residual traffic on the interstate ramps, especially during peak traffic hours, because traffic can back up quickly onto the interstate -- with traffic moving at 60 mph + it can be a safety concern. Andrew Gates, MoDOT Communications
Thanks for sharing your observations about I-44 and Hampton. Andrew Gates, MoDOT Communications
We have not conducted any traffic counts at Skinker & Vernon. In order to justify a traffic signal, there would need to be substantial, sustained traffic demands on the side street for at least 8 hours of a day. I have a feeling that wouldn't be true for Vernon. Instead I would recommend utilizing the existing signal just north of there at Olive to make a safer, protected left turn.
What I didn't see last week was the exact location in your post. I'm sorry if I missed that. We'll have someone investigate the condition you described.
If it doesn't rain, a St. Louis County contractor will begin night paving tomorrow night (June 29) on Old State Road, between Highway 109 and Old Fairway Drive, in Wildwood. Work will begin at 7 p.m. and conclude at 5 a.m. Our contractor is scheduled to pave within an identical window of time on Friday (June 30), Wednesday (July 5), Thursday (July 6) and possibly July 7. Old State consists of two lanes within our project - one in each direction. Motorists will be restricted to a single lane during the paving operation. Flag personnel will be present to control the flow of vehicles. Drivers are respectfully advised to be particularly attentive when traveling through this (and any other) work zone. David Wrone, St. Louis County
I have asked our maintenance team to take a look at the area to see what may be able to be done. Andrew Gates, MoDOT Communications
I will forward your request to our signals group for investigation. David Wrone, St. Louis County.
Reasonrules -- I have passed your observation on the I-55 ramp to our maintenance team. You can always call these items in to our customer service team at 314-275-1500. It doesn't take long for vegetation to grow in any open soil! Andrew Gates, MoDOT Communications
I have shared your concern with the maintenance team to take care of it. Thanks! Andrew Gates, MoDOT Communications
We'll have someone check it out - thanks
I've asked our traffic team and signing team to check out to make sure that the signs are correct. Andrew Gates, MoDOT Communications
We are still working on wrapping up the resurfacing project on Gravois -- that will continue through the remainder of this year. Andrew Gates, MoDOT Communications
We would like to, but there is no funding identified at this time for it. Andrew Gates, MoDOT Communications
