It should also be noted that the radar trailer was near Groveland Court which is a short distance from 85th and anecdotal evidence suggest vehicles do slow down (at least temporarily) when present. A brief footnote — we captured radar trailer data again on Groveland from June 19 to 22; average number of cars per hour dropped to 51 from 58, percent of cars going over 41 mph was exactly the same at 2.6% both times but the increase in the 36-40 mph went from 4.6% of traffic to 13% of the traffic Speed data for H2 (35 mph) for June 13 to 15 detail that 59.8% of vehicles were at or below the limit, 38% were traveling 1 to 10 mph over the limit and 2.1 % were excessively speeding with nearly 20 vehicle going over 50 mph of which one was over 65, one over 70 and one at 92 mph. We captured data again from June 19th to the 21 St and seen in increase in speed with 11.6% of the vehicles excessively speeding and the base majority of that coming from the 1-10 mph category which fell from 38% to 27.5%. Both of these studies were conducted using the "Stalker" unit is typically not noticeable unless you are aware and know where it is, thus a more accurate gauge of the situation. Over the last study we had 16 vehicles over 66 mph with 10 over 77 mph. For the time period June 14th to June 23rd our traffic enforcement efforts resulted in 130 stops throughout the city with 27 of those occurring on Groveland and 8 on H2. The majority of these stops resulted in a warning being issued (speed was under 10 but over 5) with several citations and 8 arrests (mostly related to other criminal activity). Discussion: Options to address speed include; roadway design/construction, roadway maintenance, speed bumps, active enforcement, passive enforcement (radar trailers), stop signs and a combination of some or all of the latter. Roadway design/construction is practically unavailable as an option given the recent construction of both roadways. It should be noted that Groveland was designed wider as a thru street and to allow for parking and bike travel where H2 was intentionally left narrower without shoulders. Road design theory suggests the narrower roadway helps to address speed related issues; however, our data suggests that is not the case with respect to both of these roads but especially HD. Arguably if a road is poorly maintained speeds will drop also. Like the design/build option, Mounds View, like most cities; maintains their roads thus making this minimal option a non -option as well. We have considerable experience with speed bumps which in all cases, have shown positive reinforcement in slowing traffic. However, resident and vehicle operator feedback has, in some cases, become equal in opposition to the point necessitating removal of the devices. Short term they provide relief but long term, resident opposition seems to balance against speed control. Active enforcement is the most effective, however, limited human resources make this highly desirable option, very limited. During the summer months, with the SRO (and soon to be plural) available, great enforcement can occur. However, standard staffing is 2 patrol and one supervisor who respond to calls for service as their first priority with traffic enforcement duties assigned if not on a call for service of subsequent report writing.
