Washington Manor <br />Dropping the speed limit is not an option. The City cannot just arbitrarily choose a <br />speed limit out of thin air. There is a set procedure for establishing a speed limits which <br />involves measuring the current speeds of vehicles and doing a statistical analysis of all the <br />speeds to find the 85th percentile speed. Speed limits are then set to something close to <br />that 85th percentile speed. So if -- according to the measurements -- the 85th percentile <br />speed is 40 mph -- then the speed limit is going to be set at something close to 40 mph. <br />The set procedure is design to avoid situations which could be considered a speed trap. <br />There are specific laws that prohibit speed traps. <br />More details about this process is documented here: https://dot.ca.gov/-/media/dot- <br />media/programs/traffic-operations/documents/2019-california-manual-for-setting-speed- <br />limits-a11y.pdf (https://dot.ca.gov/-/media/dot-media/programs/traffic- <br />operations/documents/2019-california-manual-for-setting-speed-limits-a11y.pdf) <br />As you may have guessed by now -- there are also regulations around the installation of <br />stop signs. The MUTCD governs this and typically government agencies won't install new <br />stop signs unless they satisfy a warrant. Most notably, a stop sign must only be <br />considered if there are more than a minimum number of vehicles arriving at a cross street <br />(usually 150 or more vehicles per hour). This is a pretty high number of vehicles and I <br />doubt that any of the cross streets between Farnsworth and Washington would qualify this <br />quantitative test. If cars are forced to stop on the main road for non-existence vehicles on <br />the side street, then drivers on the main road may be tempted to ignore the stop sign <br />because they are "always alone" and no other vehicles is at the side street. <br />Another reason for not using stop signs is that the MUTCD specifically prohibits their use <br />for speed control. Research indicates that doing so actually increases speeds and does <br />not reduce speeds. This is because drivers become frustrated at stopping when there is <br />no cross traffic (see previous paragraph) and then will drive faster between stop signs to <br />make up for lost time or worse, they will ignore the stop completely because they know that <br />there is rarely a car at the side street. <br />1Reply21 JunThank <br />Search Nextdoor <br />(https://nextdoor.com/inbox/) <br />100 <br />Page 26 of 30LEWELLING BLVD IS OUT OF CONTROL — Nextdoor <br />7/28/2020file:///C:/Users/User/Desktop/Randy/City%20of%20San%20Leandro/LEWELLING%20BLVD%20IS%20OUT%20OF%20CO... <br />89
