Published on

Albuquerque Public Schools proposes to construct a stadium and other sports facilities on Arroyo Vista north of Interstate 40, southwest of the intersection of Arroyo Vista and Tierra Pintada. The sports facilities site is referred to as the “APS Recreation Complex”. The proposed Stadium project is essentially Phase I of the “APS Recreation Complex”, and the focus of this study. A vicinity map is attached as labeled Figure 1. The “APS Recreation Complex” facility will consist of a 7,000-seat football stadium, an adjacent soccer field with a track that seats 2,600 people, soccer fields in drainage facilities, and tennis courts. Future plans include baseball fields to the east of the soccer field. The facility is not anticipated to be used for practice sessions as those will be conducted at each individual school. As the competitions are only held during specific times of the year, the traffic analysis to the site will consider the activities as “special events”.
Additionally, the City of Albuquerque is strongly considering a “City Regional Park” facility at the west edge of the “APS Recreation Complex.”

APS Stadium Traffic Analysis Study Results Executive Sumamry August 2011

  1. 1. PRELIMINARY TRAFFIC ANALYSIS RESULTS: APS Recreation Complex August 2011EXECUTIVE SUMMARYBACKGROUND Albuquerque Public Schools proposes to construct a stadium and other sports facilities onArroyo Vista north of Interstate 40, southwest of the intersection of Arroyo Vista and TierraPintada. The sports facilities site is referred to as the “APS Recreation Complex”. Theproposed Stadium project is essentially Phase I of the “APS Recreation Complex”, and thefocus of this study. A vicinity map is attached as labeled Error! Reference source not found..The “APS Recreation Complex” facility will consist of a 7,000-seat football stadium, an adjacentsoccer field with a track that seats 2,600 people, soccer fields in drainage facilities, and tenniscourts. Future plans include baseball fields to the east of the soccer field. The facility is notanticipated to be used for practice sessions as those will be conducted at each individualschool. As the competitions are only held during specific times of the year, the traffic analysis tothe site will consider the activities as “special events”. Additionally, the City of Albuquerque is strongly considering a “City Regional Park” facilityat the west edge of the “APS Recreation Complex.”SCOPING SESSION A “scoping session” was held with the City of Albuquerque and NMDOT transportationstaff. The scope of the study was determined to be the “study event” as described below, andfurther identified 6 intersections for study and analysis (see attached Figure 2).STUDY “EVENT” The event held at the Stadium with the largest attendance is expected to be certain varsityfootball games. This event became the “study event” of the traffic impact study. The studyevent is the “large attendance football game”, represented by an attendance of 3,500 people.Based on attendance figures provided by APS athletics, for the 2009 and 2010 APS varsityfootball seasons, the largest attendance was approximately 4,500 people, with an average forvarsity football games of 1,498.EXTREME INFREQUENCY OF “STUDY EVENT” As stated, the analysis considered the impacts of a large attendance football game event.Based on attendance data provided by APS Athletics, only five (5) varsity football games in thelast two (2009 & 2010) football seasons had attendance greater than that studied in this report. 1
  2. 2. PRELIMINARY TRAFFIC ANALYSIS RESULTS: APS Recreation Complex August 2011Other sporting events to be held at the “APS Recreation Complex” have attendance that is verylow compared to varsity football game attendance. As games will be played at three (3) stadiums after construction of this new WestsideStadium (Wilson, Milne and the proposed), the situation suggests that only one (1) game peryear per stadium will have the level of attendance studied in this report. This study utilized weekday evening “off peak” hour traffic levels, corresponding to the timesthat the games are actually played. This means that the peak hour of the event lags the typicalpeak hour of the adjacent street system. Additionally, roughly one-third of the high attendancevarsity games are on Saturdays (i.e., substantially further away from typical peak hour conditionsof a weekday). These factors reveal the extreme infrequency of the large varsity game (the “study event”).TRIP GENERATION COMPARISON w/PREVIOUS LAND USES OF MASTER PLAN As a result of the proposed construction of the “City Regional Park” and “APSRecreational Complex”, the average daily trips for these parcels will be reduced significantlyfrom the development alternatives permitted by their approved zoning, with most eventshappening on Friday evenings, Saturdays and occasionally Sundays. Further, both the “CityRegional Park” and “APS Recreation Complex” will not have significant everyday activitiesduring the peak commuting hours. Activities at both locations are expected to be “off-peak” andon weekends, when traffic volumes are generally much lower than during the typical traffic peakhours. Indeed, even the trip component during typical peak hour, of both facilities, is expectedto be relatively small compared to approved zoning uses. A comparison of the expected daily traffic was performed, with estimates of trip generationfor the possible Master Plan land uses vs the proposed Stadium, for the same area. Insummary, the total daily trips decrease up to 23,995 trips per day, or an over 98% reductionin daily trips. It can be seen that there will be a significant reduction in daily trips with thechange in use of the sites. A comparable numeric reduction in peak hour trips is expected, due to operation andscheduling of events at the Stadium and City Regional Park compared to the typical peak hour(this result is reflected in the Summary of Results section below).“OFF PEAK” CONDITIONS Due to the nature of the events to be held at the Stadium, atypical hours of analysis arerequired, as the varsity football games are scheduled outside the typical commute day AM/PMpeak hour, meaning that the study event is “off-peak”. Varsity football games are held 2
  3. 3. PRELIMINARY TRAFFIC ANALYSIS RESULTS: APS Recreation Complex August 2011Thursday and Friday evenings at 7:00 PM and Saturday afternoons at 1:30 PM. The typicalpeak hour for the metro area ends by 6:00 PM and Saturday afternoon traffic volumes are alsomuch lower than the typical commute day PM peak hour. For the large attendance footballgame evaluated in this report, 60% of the PM peak hour will be used as the base condition fortraffic volumes. This 60% value has been selected and used in prior studies for this athleticcomplex. The weekday evening game would be the worst case scenario since the large majorityof attendees would be arriving between 6:30 and 7:00 PM, after the PM peak hour.SUMMARY OF RESULTSLOCAL STEET NETWORKThe primary traffic analysis results indicate the following: 1. Under today’s existing roadway conditions (ie, no Stadium), traffic operations on the 6 study intersections in the vicinity of the proposed Stadium operate at acceptable levels of service in the study’s “off peak hour”. 2. In 2015, under today’s conditions (ie, no Stadium), these same 6 intersections continue to operate at acceptable levels of service in the “off-peak hour”. 3. With the Stadium in place and the local street roadway network improvements listed below, all intersections in whole will continue to operate satisfactorily at acceptable levels of service. The analysis assumed that local adjacent roadway network improvements to ArroyoVista and Tierra Pintada would be in place prior to the opening of the Stadium. Theseimprovements have been agreed to by all parties and are depicted on the attached Figure 3.These include:  The completion of Arroyo Vista as a six-lane roadway north from Ladera to Tierra Pintada.  Two lanes minimum will be constructed west of Tierra Pintada along the Stadium parcel frontage to the west entrance to the Stadium.  The Tierra Pintada crossing of the Mirehaven Arroyo will be constructed, connecting Arroyo Vista to Unser (2 lanes minimum).  Traffic signals will be constructed at the intersections of Arroyo Vista & Ladera and Arroyo Vista & Tierra Pintada. Minor street movements at Arroyo Vista & Ladera and Arroyo Vista & Tierra Pintada wouldoperate unacceptably if the traffic signals are not constructed. 3
  4. 4. PRELIMINARY TRAFFIC ANALYSIS RESULTS: APS Recreation Complex August 2011INTERSTATE SYSTEM The I40 Interstate ramp and weave operations were also analyzed, as proscribed in thescoping session. This analysis found that, without the Stadium in place, today’s existing I-40westbound 2011 PM “peak hour“ weave segment between Unser and 98th Street/Arroyo Vistaoperates at an unacceptable level of service (LOS F). This is an existing deficiency that existsregardless of the construction of the APS Stadium. In fact, in this same reach, the study event’s“off peak” hour analysis shows only a 4% (2 mph) reduction in speed. These results point out that the APS Stadium project makes no appreciable impact to theInterstate’s deficiencies and should not be held responsible for improving an existing deficientcondition on the interstate. The NMDOT is aware of the typical “peak hour” congestion in the area, however, there hasbeen no decision made on corrective approaches moving forward. Further, the TVNneighborhood has contacted the DOT seeking remedies. APS will continue to work with theNeighborhood to ask that the DOT address the known Interstate deficiency. 4
