LAND SURVEYORS SIGNAL JUSTIFICATION REPORT FOR T .H. 13 AND FIVE HAWKS AVENUE PRIOR LAKE, MINNESOTA JANUARY 1992 SRF No. 0911620 SIGNAL JUSTIFICATION REPORT FOR T.H.13 AND FIVE HAWKS AVENUE PRIOR LAKE, MINNESOTA January 1992 I hereby certify that this report was prepared by me or under my direct supervision and that I am a duly Registered Professional Engineer under the laws of the state of Minnesota. Nam~ /( ?- 107'! L Reg. No. / -9 -f/ 2... Date APPROVED: City of Prior Lake Date APPROVED: District Engineer Date I CONCUR with your determination that a traffic signal is justified at this location based on this Signal Justification Report. District, Office of Traffic Engineering Date SRF No. 0911620 INTRODUCTION This report documents the justification for a traffic signal at the intersection of T.H. 13 and Five Hawks Avenue. The intersection is located in the southern portion of Prior Lake, Minnesota (see Figure 1). Traffic signal justification will be based on the applicable warrant(s) for signal installation as outlined in the Minnesota Manual on Uniform Traffic Control Devices, (MMUTCD) and "TAU-390" , A Guide to Estimatina Traffic Sianal Warrants and Tests o~ Averaae Oaily T't"affic Estimates. Also to be considered are recommendations to roadway geometrics, proposed land use, existing and future forecast traffic volumes and planned changes in the area roadway network within the requirements of the MMUTCD, and sound traffic engineering practice. other circumstances in connection with this intersection will be offered as additional justification for signal need. EXISTING CONDITIONS This intersection is currently a four-legged intersection and connects T.H. 13, a minor arterial, with Five Hawks Avenue, which will serve as a minor collector. Five Hawks Avenue south of T.H. 13 currently serves as a driveway access for a McDonald's restaurant. The speed limit on T.H. 13 is 55 miles per hour. Currently, this intersection is "stop" controlled on the Five Hawks Avenue approaches to T. H. 13. The intersection serves existing hourly volumes of approximately 780, and 990 vehicles during the a.m. and p.m. peak hours respectively (see Figure 2). Using existing p.m. peak hour traffic volumes and existing geometrics, a traffic signal warrant analysis was conducted to determine if the need for a traffic signal currently exists. Based on this analysis, existing conditions at the intersection of T.H. 13 and Five Hawks Avenue do not satisfy the requirements of warrant 11, Peak Hour Volume Warrant. PROPOSED WORK The proposed work to the subject intersection would include the extension of Five Hawks Avenue south of T.H. 13 to connect with the proposed realignment of County Road 23 (see Figure 3). A proposed retail development, to be located in the southwest quadrant of T.H. 13 and Five Hawks Avenue, is currently planned to open in 1992. When County Road 23 is relocated, it is planned that a two-lane approach will be provided on the Five Hawks Avenue northbound approach to T.H. 13 with a combined through left-turn lane and an exclusive right-turn lane (see Figure 4). The proposed traffic signal system at T.H. 13 and Five Hawks Avenue would be a multi-phase fully actuated traffic control signal with pedestrian indications on all approaches. 1 !

In order to determine if a traffic signal would be justified in the future at the intersection of T.H. 13 and Five Hawks Avenue, year 1992 p.m. peak hour traffic volumes were estimated for the subject intersection (see Figure 5). It should be noted that traffic volumes from relocated County Road 23 were included in the calculation of the future p.m. peak hour traffic volumes. Based on the 1992 p.m. peak hour traffic forecast volumes, the intersection of T.H. 13 and Five Hawks Avenue meets the peak hour volume warrant (see Figure 6). It can, therefore, be assumed that a traffic control signal would be justified at the subject intersection by the year 1993. Additional consideration regarding signal justification is the proposed retail development to be located in the southwest quadrant of T.H. 13 and Five Hawks Avenue which is scheduled to open in 1992 and would have significant impact on the subject intersection. Future 1992 daily traffic volumes for the intersections of T.H. 13 and Five Hawks Avenue were factored from the existing p.m. peak hour turning movements to develop total two-way ADT forecast volumes (see Figure 7). The 1992 traffic forecasts include traffic assigned from relocated County Road 23 as well as traffic generated by the proposed retail development. In order to determine if a traffic signal would be justified in the future at the intersection of T.H. 13 and Five Hawks Avenue, total two-way ADT volumes were compared against the "TAU-390" Guide to Estimatina Traffic Sianal Warrant~. Based on the TAU- 390 Table (see Appendix), ADT volumes for T.H. 13 and Five Hawks Avenue would be above the 95 percent confidence level that warrants a traffic signal (assuming existing approach geometrics of one through lane in each direction on T.H. 13). with approach geometrics of two through lanes in each direction on T.H. 13 traffic signal warrants would also be met, based on the "TAU-390" table. Therefore, it can be assumed that a traffic signal would be justified at the subject intersection by year 1993. While it is apparent that most of the traffic on County Road 23 will turn right, there will be an insufficient number of gaps in northbound T.H. 13 in the a.m. peak hour to handle that right- turn volume. A free right-turn could be constructed to accommodate that movement, but the existing signal system at T.H. 13 and Duluth street is too close to Five Hawks to be able to provide an acceleration lane of sufficient length to operate safely. 6 5 310 30 5 LOW 25 w ::) z w > < en ~ 3: < ::t: W ~ ~ ~'f'~ ~ ~ ~ ..

A traffic control signal at the subject intersection would help provide safety for the school bus traffic going to and from Five Hawks Elementary School. CONCLUSION ANO RECOMMENDATIONS The installation of a traffic signal would be warranted at the intersection of T.H. 13 and Five Hawks Avenue, after the realignment of County Road 23, by meeting the requirements of warrant 11, Peak Hour Volume Warrant and the Mn/DOT "TAU-390" Guide to E~r;~atina Traffic Sianal Warrants (warrant 1). Therefore, it is recommended that the traffic signal system be constructed as part of the project to relocate County Road 23. 10 APPENDIX TAU-390 ADT VOLUMES BELOW WHICH SIGNAL IS NOT WARRANTED (95% CONFIDENCE LEVEL) Number of Lanes for Moving Traffic on Each ~~~~o?~h ADT On Major ~t;:re~t ADT On Minor Street 'Assumino D = 2:1) Maior stJ7~~t M1D.9:r st.:re~t Warrant ~ - Minimun Vehicular Movement ~ ~ 8200 ( 5750)* 3700 ( 2600)* 2 or more ~ 9875 ( 6900) 3700 ( 2600) 2 or more 2 or more 9875 ( 6900) 4925 ( 3450) ~ 2 or more 8200 ( 5750) 4925 ( 3450) Warrant 2 - Interruption of continuous Traffic ~ ~ 12325 ( 8625) 1850 ( 1300) 2 or more 1 14800 (10350) 1850 ( ~300) 2 or more 2 or more 14800 (10350) 2450 ( ~700) 1 2 or more 12325 ( 8625) 2450 ( ~700) ADT VOLUMES ABOVE WHICH SIGNAL IS WARRANTED (95% CONFIDENCE LEVEL) Number of Lanes for Moving Traffic on Each ~~OgC~ ADT On Major $treet ADT On Minor street (AssurniDO D is eaualL Maior Stre~t MJ.nQr Street Warrant ~ - Minimun Vehicular Movement ~ 2 or more 2 or more 1 ~ ~ 2 or more 2 or more 10825 13000 13000 10825 ( 7575) ( 9 ~OO) ( 9100) ( 7575) 6500 6500 8650 8650 ( 4550) ( 4550) ( 6050) ( _6050) Warrant 2 - Interruption of continuous Traffic ~ 1 16250 (1~375) 3250 ( 2275) 2 or more 1 19475 (13650) 3250 ( 2275) 2 or more 2 or more 19475 (13650) 4350 ( 3050) 1 2 or more 16250 (1~375) 4350 ( 3050) * Numbers in parentheses are 70% of values.
