5.3.3 Speed Results

5.3.3.2 Peoria – 85th Lane

This is a quiet side street off 84 th Avenue in Bell Park with a 25 mph speed limit. It had three speed humps installed well before the study began, but the residents were still not happy and wanted another hump. Since an additional vertical treatment was not warranted, other elements of Heed the Speed were employed. There was some limited education on this street prior to Wave 2 from the yard and fixed signs but little enforcement because of the low traffic volumes. The 3-D markings were installed prior to Wave 3. Five waves of data were collected with the results shown in Table 61 and Figure 9.

There was no meaningful change on 85 th Lane , which is not surprising given the low baseline speeds and the extremely small proportion of drivers going 7 or more miles over the limit. It is curious that the residents were complaining to the city prior to the study as the baseline (Wave 1) speed profile seems quite benign. The quiet nature of the test segment is also clearly indicated by the relatively low volume of traffic. The 48-hour volumes on 85 th Lane were just over 10 percent of the number of vehicles seen on 84 th Avenue , an adjacent street. Also, the traffic volume is largely steady from wave-to-wave suggesting no significant diversion.
