C www dksassociates corn TO: City of Tigard [XPIRES: FROM: Peter L.Coffey,PE SUBJECT: Impacts on Road Capacity of Southwest Corridor Light Rail Transit Project Options The City of Tigard Charter requires the City to oppose any high-capacity transit project,such as the proposed options to extend light rail service to Tigard,unless the voters first approve an authorization ordinance supporting the project.The Charter also creates requirements for what must be included In the authorization ordinance.One requirement is that the ordinance must describe the total amount of road capacity or potential future road capacity that may be reduced by the project options. The Charter requirement does not call for a comprehensive analysis of the impacts and benefits of the light rail options on the road network,it solely focuses on the reduction in road or potential road capacity within the five mile radius around the City of Tigard boundary,A reduction in public right-of- way that is not currently used for a roadway but that could potentially be available for new road or highway lanes in the future must be addressed,whether or not there is any plan for the additional road or highway lanes. Thus the Charter requires road capacity to be measured on a spatial(or area)basis and to consider the capacity of unused rights-of-way on which no roadways are currently planned.To address the unique requirements of the Charter,the City enacted an ordinance that established the"Methodology to Estimate the Total Amount of Road Capacity Reduced by a New High-Capacity Transit Corridor,"which sets in the city's laws a definitive and transparent approach to addressing the Charter requirement regarding road capacity. This report is prepared in accordance with city's required methodology,and uses the terms defined therein.The analysis is based on alignment options,information,and data available at the time the authorization ordinance is referred to the voters by the City Council. The analysis and findings of this analysis do not supplant the need for future traffic analysis that will be done for the Environmental Impact Statement. The report finds that while causing a slight loss of road capacity along the overall transportation corridor between Tigard and Portland,the proposed light rail options cause substantial Increase In the person- trip capacity of the overall transportation corridor between Tigard and Portland.No loss of existing road capacity occurs In Tigard,although light rail options use some unused right-of-way,primarily alongside E1illlUlt B 50014-36799 Final Referral resolution.docACAK16/2212016 Impacts on Road Capacity of the Southwest Corridor Light Rail Transit Project Options June 20,2016 Page 2 of Interstate 5 that potentially could be available for added lanes should additional lanes be planned in the future. None of the light rail options impact Pacific Highway in Tigard. Background Traffic Analysis of Barbur Boulevard Corridor This analysis of the capacity impacts of the Southwest Corridor light rail options on existing roadways focuses on Barbur Boulevard because it is the existing roadway(as opposed to possible future roadways, which are addressed separately later in this report)affected by the proposed light rail options between Tigard and Portland. No lanes on Interstate 5 nor on Pacific Highway in Tigard are impacted by the proposed light rail options,except to the extent that the light rail options may attract more riders and thereby reduce auto traffic on these facilities.' There have been several recent traffic analyses of the Southwest Corridor and Barbur Boulevard in connection with the proposed options to extend light rail to Tigard that evaluated the corridor from downtown Portland to Tigard and Tualatin. ' These previous traffic analyses concluded that key signalized intersections in the year 2035 will either continue to operate within mobility targets s or will not significantly worsen from 2035 No-build conditions with the addition of light rail along Barbur Boulevard. The City of Portland recently adopted the Barbur Concept Plan for the six-mile Barbur Boulevard corridor from Portland's Central City to the Tigard city limit. Key provisions of this plan are to "establish safe and comfortable conditions for active transportation"in the corridor, "complete pedestrian and bicycle connections and access to transit throughout the corridor,"and "prioritize active transportation improvements on Barbur."4 To make Barbur Boulevard more pedestrian-and bicycle-friendly,the traffic signals on Barbur Boulevard will need to devote more"green time"for cross-streets to make n easier for pedestrians and bicyclists to cross Barbur Boulevard. Consequently there will be less"green time"for the north-south motor vehicle traffic on mainline Barbur Boulevard.This change in signal timing along Barbur Boulevard results in decreases in Motor Vehicle Capacity,and is anticipated whether or not light rail is extended to Tigard. 'Along Interstate 5,all existing lanes remain in each direction and along Barbur Boulevard,south of the Naito Parkway confluence,two through lanes remain in each direction.

However,the changes in the configuration of lanes on Barbur Boulevard may not directly translate into a material change in the Motor Vehicle Capacity of Barbur Boulevard,as the operations of the intersections along Barbur Boulevard must also be taken into consideration. The design of intersections(including traffic signals)along arterial roadways and interchanges along freeway segments(where weaving and merging conditions exist)are major considerations in determining the Motor Vehicle Capacity of these facilities.Intersections and interchanges are typically the controlling bottlenecks of traffic flow and the ability of a roadway system to efficiently carry traffic is generally diminished in these areas.The main consequence of a bottleneck is an immediate reduction in capacity of the roadway.For arterial roadways such as Barbur Boulevard,the controlling bottlenecks are signalized intersections,and the most congested of these intersections are referred to as Critical Intersections. Net Motor Vehicle Capacity Reduction on Existing Roadways Using the recent traffic analyses for the SW Corridor,I the Barbur Boulevard corridor was assessed to identify Criticol Intersections associated with the proposed Alignment Options.Since Interstate 5, Pacific Highway in Tigard,and other corridor routes are not impacted by any Alignment Option,there was no need to assess Critical Intersections on those facilities. Intersections on Barbur Boulevard were identified as Critical Intersections if the overall intersection Volume to Capacity Ratio(V/C Ratio)forecasted for the year 2035 was greater than 0.90.The following intersections met this criterion' • Barbur Boulevard and 60�Avenue(AM peak) • Barbur Boulevard and Capitol Highway(AM and PM peak) • Barbur Boulevard and 24"'Avenue/1-5 SB Off-Ramp(AM peak) s SW Condor Supplemental Refinement Traffic Impact Anatos Executiwe Summary Traffic Report,DKS Associates, March 16,2016 and Final SW Corridor Traffic Analysis and Operations Memorandum,DKS Associates,July 29,2014.E The 4'"Avenue/Caruthers StreeVBroadway intersection in downtown Portland is controlled by downstream congestion at the 69'Avenue/Broadway intersection,the on-ramp to 1-405 and other downstream congestion locations.The reconfiguration of this intersection does not impact the Motor Vehicle Capacity of the roadway system in this area of closely spaced traffic signals.The downstream constraint(611vBroadway)is not changed by this project.Therefore,the 4t'Avenue'Caruthers StreeVBroadway intersection was not considered a Critical Intersection for this analysis.

During the AM Peak-Hour(future year conditions)traffic volumes are very directional on Barbur Boulevard with northbound volumes approximately two-to-four times greater than southbound traffic volumes and VIC Ratios for the northbound through movements are also significantly higher than for the southbound movements(see Table 1A and Table 1B).Therefore,Motor Vehicle Capacity reductions for the AM Peak Hour were evaluated in the northbound(critical)direction.During the PM peak hour (future year conditions)traffic volumes were relatively balanced in both directions and therefore Motor Vehicle Capacity reductions were evaluated in both directions on Barbur Boulevard. Tables 1A and 1B show the estimated reduction in the Motor Vehicle Capacity of each Critical Intersection along Barbur Boulevard caused by the Alignment Options. Reduced Motor Vehicle Capacity is calculated as the difference of the Motor Vehicle Copocity of the Critical Intersection without the Alignment Option minus the Motor Vehicle Capacity of the Critical Intersection with the Alignment Option.To illustrate the range of potential impacts of the Alignment Options,Table 1A shows results for the Alignment Option having the greatest impact on Motor Vehicle Capacity on Barbur Boulevard and Table 1B shows results for the Alignment Option with the least impact. The Motor Vehicle Capacity impacts of Alignment Options on the Critical Intersections are used to determine the overall Motor Vehicle Capacity impact on the Barbur Boulevard corridor.Alignment Options impact the overall Motor Vehicle Capacity of a roadway in two distinct ways (i)changes in the physical configuration and traffic signalization of Critical Intersections,as described above,and Iii) changes in the volume of on-street buses on Barbur Boulevard.With the introduction of light rail,some buses currently operating on Barbur Boulevard are no longer required because they are replaced by light rail vehicles operating on a dedicated right-of-way.This makes additional Motor Vehicle Capacity °The 4''Avenue/Caruthers Street/Bioadway intersection in downtown Portland is controlled by downstream congestion at the 61 Avenue/Broadway intersection,the on-ramp to 1-405 and other downstream congestion locations.The reconfiguration of this intersection does not impact the Motor Vehicle Capacity of the roadway system in this area of closely spaced traffic signals.The downstream constraint(61h/Broadway)is not changed by this project.Therefore,the 4'"Avon ue%Caruthers Street/Broadway intersection was not considered a Critical Intersection for this analysis '2000 Highway Capacity Manual,Transportation Research Board,Special Report 209,2000,Chapter 16, Washington DC,2000.

In calculating the Net Motor Vehicle Capacity Reduction caused by an Ahgnment Option,the reduction in the overall corridor capacity of Barbur Boulevard is estimated as the highest Reduced Motor Vehicle Capacity among all of the evaluated Critical Intersections for the Alignment Option. The capacity made available to truck and auto traffic by reducing the volume of on-street buses is estimated by multiplying the reduction in the forecasted 2035 Peak Hour,Peak Direction on-street bus volume caused by the Alignment Option by the bus-auto capacity equivalence factor I bus uses capacity of 2 autos).These factors yield the following estimated Net Motor Vehicle Capacity Reduction on Barbur Boulevard in year 2035: Northbound PM Peak Hour: 170 vehicles per hour° Southbound PM Peak Hour. 160 vehicles per hour° Northbound AM Peak Hour: 100 vehicles per hour"to 190 vehicles per hour" As mentioned earlier,the Alignment Options do not impact motor vehicle capacity on Interstate 5 or Pacific Highway in Tigard. Percentage Reduction in Total Radial Corridor Motor Vehicle Capacity The estimated Net Motor Vehicle Capacity Reduction on Barbur Boulevard can best be understood in the context of the overall transportation corridor serving travel between Tigard and Portland While there are many routes that may be used to travel between Tigard and Portland,this analysis uses the three major routes included in Metro's Mobility Corridor#21'as the overall Portland Central City to Tigard/Tualatin motor vehicle corridor.As shown in Figure 2,Metro's Mobility Corridor#2 includes: • Interstate 5(shown in blue in Figure 2) • SW Barbur Boulevard (99W),then along Pacific Highway and 72"c Avenue(shown in red in Figure 2) • SW Macadam Avenue/OR 43/A Avenue/Boones Ferry Road(shown in yellow in Figure 2) Using the Metro Transportation Model and more detailed estimates for some segments of Barbur Boulevard,the aggregate Motor Vehicle Capacity for each of four segments of each of the three routes F 170 vehicles per hour for both the most and least impactful Alignment Options 160 vehicles per hour is rounded up from 156 or 159 vehicles per hour,and is the same for the Alignment Options with the least and greatest impact on Motor Vehicle Capacity. "100 vehicles per hour for the Alignment Option with the least impact on Motor Vehicle Capacity " 190 vehicles per hour is rounded up from 186 vehicles per hour for the Alignment Option with the greatest impact on Motor Vehicles Capacity.

The Percentage Reduction in Total Radial Corridor Motor Vehicle Capacity is the Net Motor Vehicle Capacity Reduction of an Alignment Option(from Table lA and Table 1B)divided by the Total Rodio) Corridor Motor Vehicle Capacity(8,600 vehicles per hour).To estimate the range Net Motor Vehicle Capacity Reduction of the Alignment Options,the largest value from Table 1A(190 vehicles per hour- rounded)and the largest value from Table 1B(170 vehicles per hour)were used- As shown in Table 2,the combination of the changes in traffic signalization(which are planned with our wrthout light rail)and the lane displacements and additional changes in traffic signalization caused by the Alignment Options reduce the motor vehicle capacity on the main facilities serving Tigard-Portland traffic by about a two percent(2%)(the high and low estimates round to about same percent). Percentage Reduction in Tigard Subarea Motor Vehicle Capacity Section 53 of the City of Tigard Charter focuses on an area that extends five miles from the boundary of the City of Tigard.To consider Motor Vehicle Capacity impacts in this context,a Tigard Subarea was created as an area with a boundary that is five miles in all directions from the boundary of the City of Tigard. While the capacity of each(non-local)roadway link in the Tigard Subarea is available from the Metro Transportation Model,a methodology is required to determine the composite capacity within the Tigard Subarea.The Total Tigard Subarea Vehicle Capacity was estimated as the aggregate sum of the weighted capacity of each link coded in the Metro Transportation Model within the subarea.The weight for a link was calculated as the length of the link.The length and bi-directional capacity of each link was derived from the Metro Transportation Model.The length-weighted capacity of the Tigard Subarea was calculated for the No Build scenario(without any Alignment Option)and a scenario with an Alignment Option and the Percentage Reduction in Tigard Subarea Motor Vehicle Capacity was estimated as the percentage difference in these scenarios. As shown in Table 3,the Alignment Options are estimated to decrease the length-weighted Motor Vehicle Capacity of the Tigard Subarea by about 0.03 percent(3/1001,of 1%).This value will be similar for any of the Alignment Options.

The Person Trip Capacity of the Radial Corridor was determined for Alignment Options with the greatest impact on Motor Vehick Copocity and the least impact on Motor Vehick Capacity, as well as for a scenario without an Alignment Option(No-Build).Table 4 shows the steps utilized to determine the Percentage Increase in Person Trip Capacity.The Increased Person Trip Capacity on transit resulting from the introduction of the light rail options was determined by multiplying the estimated maximum number of light rail trains that can be operated in the Peak Hour by the person capacity of a light rail train,and then subtracting the person capacity of the on-street buses that were removed from Barbur Boulevard due to light rail.The Person Trip Capacity in motor vehicles was estimated by multiplying the Net Total Radial Corridor Motor Vehicle Capacity from Table 2 by an assumed vehicle occupancy rate of 1.4.The Increased Person Trip Capacity of the Radial Corridor is the sum in the Radial Corridor of the increased person trip capacity on transit and the decreased person trip capacity in motor vehicles. The Percentage Increase in Person Trip Capacity is estimated to be 36 to 37 percent for all Alignment Options(the high and low estimate round to about the same percentage).Thus,while the introduction of light rail reduces the Motor Vehicle Capacity of the Radial Corridor by about 2%,it increases the Person Trip Capacity of the Radial Corridor by about 36 to 37 percent.

As a practical matter,there are many constraints to adding Motor Vehicle Capacity to either Interstate 5 or Barbur Boulevard.The most significant constraint may be a lack of nght-of-way in the necessary (bottleneck)locations.Adding a travel lane along Interstate 5 will require widening the roadway for an additional travel lane or lanes and widening the shoulders on both sides of the roadway to bring them up to ODOT/US DOT standards. It also likely requires reconstruction of all interchanges, reconstruction of many bridges and overpasses which connect surface streets over 1-5,substantial new walls and most likely an adjustment to the roadway alignment to straighten out some of the curved sections to provide adequate sight distance meeting current standards.In addition to the reconstruction challenges,this will require ODOT to obtain additional right-of-way that they do not currently own. Along Barbur Boulevard, expanding capacity from today's conditions requires not only additional travel lanes at bottleneck locations,but the addition of standard-width sidewalks,bicycle facilities,ADA treatments,water quality facilities,and other improvements to bring the roadway up to applicable standards. Reduced Motor Vehicle Capacity of Unused Public ROW To address this Charter requirement,the Reduced Motor Vehicle Capacity of the Unused Public ROW was estimated for the Alignment Options with the greatest and least impact on Unused Public ROW that 'could otherwise provide additional motor vehicle capacity at a future date.' This does not include all public right-of-way in the corridor currently not being used for a transportation facility(Unused Public ROW),as much of the Unused Public ROW is too small to accommodate a new lane or road and/or is located where a new lane or road cannot efficiently function.The Reduced Motor Vehicle Capacity of the Unused Public ROW only considers Unused Public ROW that 'could otherwise provide additional motor vehicle capacity at a future date,"which is referred to as Useful Unused Public ROW in this analysis. For each applicable Alignment Option,Useful Unused Public ROW was identified as follows • The roadway design standards or criteria (including cross-section specifications) applicable to expanding the number of lanes on the roadway was identified, cross-sections include the width of all bicycle facilities, sidewalks, shoulders, medians, or other features needed to comply with the design standard or criteria. • Based on the cross-section required to comply with applicable design standards or criteria, the width (i.e., distance from the centerline of the roadway) of Unused Public ROW needed to added one or more lanes was determined. Exhibit B 50014-36799 Final Referral resolution.docx ICAK/6/2212016 Impacts on Road Capacity of the Southwest Corridor Light Rail Transit Project Options June 20,2016 Page 15 • Useful Unused Public ROW was identified as the area of Unused Public ROW displaced by an Alignment Option 13 where : The width of the Unused Public ROW is sufficient to accommodate one or more additional lanes in compliance with applicable design standards and criteria,and : If the roadway to be expanded is a freeway or throughway (i.e., 1-5),the location of the Unused Public ROW either (1)extends along the roadway for a distance of at least one- half of one mile or(II)addresses a system bottleneck;or : If the roadway to be expanded is an arterial (i.e., Barbur Boulevard), the location of the Unused Public ROW addresses a system bottleneck. The location of Useful Unused Public ROW and Unused Public ROW impacted by the Alignment Options was identified, based on the criteria described above Figure 3 shows the Unused Public ROW for the highest impact scenario while Figure 4 shows the Unused Public ROW for the lowest impact scenario. Table 5 shows the Reduced Motor Vehicle Capacity of Unused Public ROW,which is measured by the area(in acres)of Useful Unused Public ROW displaced by the Alignment Option.

Thus,the Alignment Options are estimated to displace 1.3-5.0 acres of public ROW could potentially provide additional motor vehicle capacity at a future date.Keep in mind that this estimate does not consider all of the practical limitations of providing additional lanes.
