last three) to make <br />sure you are getting <br />a reasonable picture <br />of the are~ Local <br />polico departments, <br /> <br />dq3artments, and/or <br />the department of <br />transportation are <br /> <br />for accident data. <br /> <br />2. Traffic volume <br /> <br />study_ - Traffic count <br />data is collected and <br />analyzed by putting <br />traffic count <br />mach|n~ Oil each <br />approach to an <br />intersection for a 48 <br />hour period during <br />the week (Monday. <br />Friday). <br /> <br />- - Sight lines for <br /> traffic approaching <br /> the intersection are <br /> reviewed and <br /> analyzed using field <br /> measurements. <br /> <br />Determine the Solution <br /> <br />After conducting the appropriate <br />studies, you my find the <br />following: <br /> <br />You could not <br />verify the problem <br />or the problem is <br />not si~ificant <br />enough to justify <br />any action. <br /> <br />There is a probl6m, <br />but there are more <br />effective solutions <br />titan the installation <br />of a stop sign. <br /> <br />3. The requested stop <br /> sign is an effective <br /> <br />solution to the <br />problem. <br /> <br />If the problem is not significant <br />enough to warrant a stop sign, <br />explain this to the person <br />requesting the sign. ,Assure them <br />that the situation wilt be <br />reviewed on a periodic basis and <br />action wilt be taken should the <br />situation change. If more <br />effective solutions to the problem <br />exist, explain the alternatives and <br />what action will be taken to <br />correct the problem. If a stop <br />sign is the best solution to the <br />problem, give the person <br />requesting thc sign an accurate <br />estimate oa how long it will take <br />before thc sign is ia place. <br />Usually stop signs must be <br />approved by the local <br />commigs|on, council, or beard, <br />which may meet only once or <br />twice a month. <br /> <br />Keep Good Records <br /> <br />All requests for stop signs should <br />be documented, whether or not <br />they result in the installation of a <br />stop sign. These records are <br />useful for future inquiries about <br />why there is or is not a stop sign <br />at a particular location. Keeping <br />good records (and simply having <br />a good record system) is a key <br />factor in su~y defending <br />your agency in any legal action <br />that may arise. <br /> <br />Prepared by George Calebaugh, <br />P.E., Senior Transportation <br />Engineer with RLK-Kuusisto, Ltd. <br /> <br />For mom information, contact one <br />of our four offices: <br /> <br />Minnetonka (612) 933-0972 <br />St. Paul (612) 645-0393 <br />Hibbing (218) 262-5528 <br />Twin Ports (218) 720-6219 <br /> <br />Where to use o stop <br />sign: <br /> <br />Intersections with a <br />demonstrated accident <br />problem involving <br />right-angle mm and <br />left-turn accidents. <br /> <br />Intersections with sight <br />obstructions on the <br />approaches that restrict <br />sight lines of <br />conflicting traffic. <br /> <br />Uncontrolled <br />intersections with much <br />heavier traffic on one. <br />street than on the other. <br /> <br />Intersections with <br />heavy traffic on <br />conflicting approaches. <br /> <br />Problems that cannot <br />be addressed with <br />stop signs: <br /> <br />Reducing speeding. <br /> <br />Eliminating cut- <br />through traffic on <br />residendal streets. <br /> <br />· Providing a safer <br /> environment for <br /> <br /> I <br /> I <br /> I <br /> I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br /> <br />
