CITY OF SOUTH BEND DEPARTMENT OF PUBLIC WORKS DIVISION OF ENGINEERING TO: Board of Public Works THROUGH: Kara Boyles, Ph.D., P.E., City Engineer FROM: Charlotte Brach, P.E., Senior Engineer SUBJECT: Linden and Kaley Multi-Way Stop Warrant Analysis (TR18-113) DATE: December 22, 2023 Purpose The purpose of this study is to determine whether any traffic control improvements are warranted at the intersection of Linden Avenue and Kaley Street. The Engineering Division has received a request from a resident 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 Linden Ave is classified as a minor arterial. Kaley Street is classified as a Minor Collector. Both Linden Ave and Kaley Street have one travel lane per direction. This intersection is located in a residential and industrial area. 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 1 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 This intersection is currently controlled by a two-way stop where Linden Ave stops, and Kaley Street does not. Northbound Kaley Street ends at Linden Ave and does not continue north. Kaley Street continues 240 feet to the south where it reaches a T-intersection with Holland Street, which is controlled by a one-way stop. Westbound traffic on Holland Street stops, and Kaley Street is the through street. Linden Ave continues 350 feet to the east where it reaches an intersection with Meade Street, which is an uncontrolled intersection. Linden Ave continues 2,660 feet to the west where it reaches a T-intersection with Falcon Street, which is controlled by a one-way stop. Northbound traffic on Falcon Street stops and Linden Ave is the through street. Street Geometry Linden Ave is a 39 ft. wide roadway. On both approaches, parking is restricted on both sides of the street. Kaley Street is a 29 ft. wide roadway. Parking is restricted on both sides of the street. Traffic Counts Traffic Counts were taken by MACOG on September 2, 2020 by automatic pneumatic tube and the following are the results: Date Time Kaley Street Northbound Linden Ave Westbound Linden Ave Eastbound Total of Kaley Street Approaches Total of Linden Ave Approaches 9/2/2020 12:00 AM 21 40 45 21 85 9/2/2020 1:00 AM 17 27 19 17 46 9/2/2020 2:00 AM 8 14 15 8 29 9/2/2020 3:00 AM 10 17 15 10 32 9/2/2020 4:00 AM 26 24 27 26 51 9/2/2020 5:00 AM 34 28 37 34 65 9/2/2020 6:00 AM 60 55 64 60 119 9/2/2020 7:00 AM 82 102 127 82 229 9/2/2020 8:00 AM 89 121 123 89 244 9/2/2020 9:00 AM 76 95 96 76 191 9/2/2020 10:00 AM 88 132 116 88 248 9/2/2020 11:00 AM 123 148 132 123 280 9/2/2020 12:00 PM 115 176 131 115 307 9/2/2020 1:00 PM 119 174 141 119 315 9/2/2020 2:00 PM 141 215 153 141 368 9/2/2020 3:00 PM 152 288 224 152 512 9/2/2020 4:00 PM 181 308 178 181 486 9/2/2020 5:00 PM 218 320 174 218 494 9/2/2020 6:00 PM 139 258 131 139 389 9/2/2020 7:00 PM 154 211 147 154 358 We deliver services that empower everyone to thrive!! 9/2/2020 8:00 PM 136 175 132 136 307 9/2/2020 9:00 PM 92 137 89 92 226 9/2/2020 10:00 PM 76 99 76 76 175 9/2/2020 11:00 PM 34 79 44 34 123 Total 2157 3164 2392 2157 5556 The cells highlighted in green show the eight hours of the day with the highest traffic counts on the major street approaches. The cells highlighted in blue show the traffic on the minor street for the same eight hours of the day. Collision Data Three years of collision records were accessed in the Aries portal (December 2018 – December 2021). Nine crashes occurred at this intersection in this three-year period. One of these crashes was a right-angle crash. Other Considerations Optional criteria for an all-way stop include the need to control left turn conflicts, high pedestrian volumes and vehicle/pedestrian conflicts, visibility conflicts, and two similar residential neighborhood streets. There is a building on the southwest corner of the intersection that causes visibility conflicts for northbound and eastbound traffic at the intersection. Recommendation The traffic volume and crash data at the intersection does not warrant a multi- way stop. However, it is likely that if this intersection was a 4 -way intersection, the volumes would warrant a multi-way stop, due to the high volume of northbound traffic on Kaley Street. Southbound traffic on Kaley Street was also collected and the volume of traffic from Linden Ave proceeding southbound on Kaley Street is also high. This intersection is also currently set up as a two-way stop, which is not typical for a T- intersection. Switching it to a one-way stop on Kaley Street could cause additional issues since traffic on Kaley is used to not having to stop. Due to the traffic volumes, site distance concerns, and traffic safety concerns created by the current intersection controls, as well as the traffic safety concerns that would be caused by switching the intersection to a one-way stop, the Engineering Division recommends the installation of a stop sign on Kaley Street at the intersection with Linden Ave to make the intersection an all-way stop. The Engineering Division also recommends installing a stop sign ahead warning sign approximately 200 ft. back from the intersection to alert drivers of the new stop sign. In the implementation of this new stop sign, the Engineering Division recommends the use of a flashing stop sign to alert drivers of this chan ge. This device will be left in place for 90 days, then it will be replaced with a regular stop sign. Refer to the attached display for more information.
