The Engineering Division has received a request 0 from VPA to install a multi -way stop at this intersection. This memo summarizes the warrant analysis conducted to assess the need for a permanent all -way stop at this intersection and the proposed recommendation. Location/Description. Both Lafayette Boulevard and Riverside Drive are classified as local streets, and both have one travel lane per direction. Warrants The Manual on Uniform Traffic Control Devices sets forth the following requirements to warrant the installation of multi -way stop control: The following criteria should be considered in the engineering study for a multi -way STOP sign installation: A. Where traffic control signals are justified, the multi -way stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the installation of the traffic control signal. B. Five or more reported crashes in a 12-month period that are susceptible to correction by a multi - way stop installation. Such crashes include right -turn and left -turn collisions as well as right- angle collisions. C. Minimum volumes: 1. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours of an average day; and 2. The combined vehicular, pedestrian, and bicycle volume entering the intersection from the minor street approaches (total of both approaches) averages at least 200 units per hour for the same 8 hours, with an average delay to minor -street vehicular traffic of at least 30 seconds per vehicle during the highest hour; but We deliver services that empower everyone to thrive!! 3. If the 85th-percentile approach speed of the major -street traffic exceeds 40 mph, the minimum vehicular volume warrants are 70 percent of the values provided in Items I and 2. D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to 80 percent of the minimum values. Criterion C.3 is excluded from this condition. Existing Traffic Controls The intersection is currently controlled by a one-way stop on Lafayette Boulevard where Riverside Drive is the through street. Lafayette Boulevard does not continue north of this intersection. Lafayette Boulevard continues 270 ft to the south to a two-way stop - controlled intersection with Park Lane where Lafayette Boulevard stops, and Park Lane is the through street. Riverside Drive continues 945 ft to the east until reaching a two-way stop controlled intersection with Michigan Street where Riverside Drive stops and Michigan Street is the through street. Riverside Drive continues 670 ft west to a one-way stop -controlled intersection with Park Avenue where Park Avenue stops and Riverside Drive is the through street. Street Geometry Lafayette Boulevard is a 35 ft wide roadway. Due to a school zone, parking is restricted between 7 AM and 4 PM on school days on northbound side of Lafayette Boulevard. Parking is restricted at all times on the southbound side of Lafayette boulevard. Riverside Drive is a 30 ft wide roadway. Parking is not restricted along either side of the roadway. The speed limit along Riverside Drive is 20 MPH. The speed limit along Lafayette Boulevard is 25 MPH when children are present. Traffic Counts were taken by MACOG on 5/28/2019 - 5/30/2019 by automatic pneumatic tube counters at each approach of this intersection and the following are the results: Lafayette Lafayette Riverside Riverside Total of Lafayette Total of Date Time Boulevard Boulevard Drive Drive Boulevard Riverside Drive Northbound Southbound Westbound Eastbound Approaches Approaches 11:00 AM 57 37 48 74 ......... 94 122 Q 12:00 PM � _ 5�5 �_.... _— �.����_...... 47 64 62 102 126 5/28/2019 ....... 1:0 0 PM 73 59 67 87 132 154 5/28/2019 2:00 PM 88 67 75 103 155 1 178 5/28/2019 3:00 PM 118 63 69 100 181 169 5/28/2019 4:00 PM � 119 4 1 85 71 160 156 1 5:00 PM 131 44 107 84 175 191 2019 6:00 PM 69 37 61 63 106 124 . ... 5/28/2019 _..--... 7:00 PM 50 25 _.. 57 35 75 92 5/28/2019 8:00 PM 43. ............ . 15 5...._.... 2 ........3.3.....�����������__ 34 ....� 56 .��.....-65 86 _.....fi4.............�...._�.� ...5/28/2019 .P�M..�.�. 9:00 47___m�............ ..........._..�.��1$ m.....��� 31 ..3,� 5/28/2019 10:00 PM ...._...... 26 9��,,,._ 19 2.6 5 _ ... 45 5/28/2019 ...... 11:00 PM _.... 20 ��... 3 15�.�.� 10 _.�.. __ ... ..._ 23 w.............._....�.. 25 _�._� mm5/28/2019 �...�m 12:00 AM �����. e..,_ 7 � .... 3 8 .........m. 4 10 12 5/29/2019 ........... 1:00 AM 7 3 3 5 _. 10 �......... , 8 5/29/2019 d �W.._._ 2:00 AM _ .. 4 �. 1 1 5 ..... 3 __.... ... 5 8 z 5/29/2019 / 9/2019 ...... 3:00 AM _..... 0 .m... .............. ... 3 4 �� 7 _....�.....mm..m 3 _....... 11 5/29/2019 4:00 AM......�. 4 _� ......, 1 4 6 5 5/29/2019 5:OO AM 4 12 8 26 16 34 We deliver services that empower everyone to thrive!! 5/29/2019 6:00 AM 12 44 20 74 56 94 019 7:00 AM . ... 87 _ 108 27 176 195 203 5/29/2019.. 8:00 AM 63 118 35 m 1.76 ...._ 181 211 5/29/2019 9:00 AM 44 55 35 83 99 118 5/29/2019 . 10:00AM. ...AM....... 62 4_..�d__ 2 ..................... 47 �_... ............ 57 ........._�. 104 .... 104 5/29/2019 11:00 - 57 .. 56 .� �..._. 64,. ,,. __......................��..��............�........ 65 113 .............�6 129 5/29/2019 .....�_.........1 12:00 P.M..... _ 84 58 �����............. 64 .. _. 75 �....� — . � ...._............. 142 �........... .� 139 5/29/2�01�9 00 PM... 63 56 �. 42 .m.....m�.... 77 �_.......�. ... 119 �_Y_ _.�.�. 119 5/29/2019 �.....5/29/2019 2:00 PM ..�.. 93 � 66 _..... 548.�.. 3 �..._ 159 .u.._..�............._. _........ 137 _ 3:00 PM �.�..........108��..�. 109__...._.e.. 81 �� 109 .._. �����.....�._m..� 190 .._m _....._....... 185 ... ..� 51.88 . w. 78 __.� .. ..... 159 166� �.........� 5/29/2019.�m 5�:00 PM 119 ,...ASo„ .......... 109 _ 8.0�...._169 _ .� ... 189...... 5/29/2019 .. ..._ ...., 6:00 PM .. .._. 66 ..,... .............. 68 99 70 _,_... 134 169 5/29/2019 7:00 PM...__. _ 47 .............�............................73 ... ...53 �.. 90 6 1 ��� .�....�. 10 0 151 5/29/2019 .� 8:00 PM _ �......................34............... 48 �.....��_ 53.....mm...............�............�.�.�.�.�44,� ��........................��.�.....�..........uu m..�...... 97 5/29/2019 9:00 PMm �............�� �.�..25 18 m..... ....�.......... �.�.�.�.....................3�4 33 _...�.............._...,,,52 � 67....................�.... 5/29/2019 10:00 PM 13 .....3.7mm....���. 24 �.........�aada 38 �......6.1....���m.......r_._ 5/29/2019 11.00 PM 13 8 me.__ ... 24 .. 15 21 39 5/29/2019 _5/30/2019- 12:00 AM ------ _ - 12 5�� 17 13 1:00AM 6",_ 1 T_ .... 3 7 ........, m 10 30/2019 2:00 AM ��. ........ 6 _ ....... ......r 2 5 4 8 9 5/30/2019 3:00 AM _._........� 3 ��w _ 2 5 4 - 5 9 5/30/2019 4:00 AM ....... 1 ........ 6 2 12 7 14 5/30/2019 5:00 AM 2 �...�.,_.�38.. .. �... _.w 10 ,... 7.� ._...... 1 .,,,,..,� _ 20 .......�.. 31 5/30/20196:00AM���... ........ 17 ��...m�.�.�.�.�.�..43......_�...........�. ..... � 15 ....................�7��...._..........m�.w� 4 .��..........................................�..., 60 m„ 89 5.... /30/2019 7:00 AM 81 110 38 .. 200 191 238 /30/2019 ......9:00 8:00 AM .... 81 . �...� 106 28 157 187 185 5/30/2019 AM 44 _ .. ��..m. 50 .� � 42 .m.m.�.._....�_.� .... 70 �.....�_............��.�..�.........�a_. 94 112 The cells highlighted in blue show the eight hours of the day with the highest traffic counts on the major street approaches. The cells highlighted in green show the traffic on the minor street for the same eight hours of the day. Collision Data Four years of collision records were accessed in the Aries portal for the intersection of Riverside Drive and Lafayette Boulevard. One collision was reported during the time accessed. This incident was the result of a driver rear -ending the vehicle in front of him. Recommendation The traffic counts and collision data do not warrant reconfiguring the Lafayette Boulevard and Riverside Drive intersection to an all -way stop. However, there are several other factors that impact the safety of this intersection. It is surrounded on all sides by Leeper Park, and with the improvements happening at the park, pedestrian crossings will be encouraged. Walking paths will also be connected on the north side of the intersection and walking paths throughout the park will be improved. The goal of the Leeper Park Improvements Project is to increase pedestrian traffic in the area and encourage increased use of the park and the paths. With that increase in pedestrian We deliver services that empower everyone to thrive!! traffic will come the increased need to improve safety at this intersection, as part of the park as a whole. Based on other criteria that may be considered in an engineering study according to the MUTCD, specifically "the need to control vehicle/pedestrian conflicts near locations that generate high pedestrian volumes," the Engineering Division recommends the installation of an all -way stop at this intersection.
