an appropriate balance between delays to the traveling public in the work zone and the cost of construction and maintenance. It is applicable to singlelane closures (and multilane closures on sixlane roadways) related to construction and maintenance activities on roads controlled by the Colorado Department of Transportation (CDOT. It is based on extensive data analyses and estimates of delays expected during lane closures. The LCS addresses weekday and weekend traffic demand and considers temporal variations in traffic volume occurring over a typical 24hour period. The LCS also accounts for seasonal variations in traffic volumes.Prior to the completion of the 1stEdition of the Region 4 LCS (published in 2009), lane closure decisions were primarily based on field observations, previous experience, and engineering judgment. Use of the nformation presented in this LCS

For instance, a highway segment may be within the recommended delay threshold to allow a lane closure, but the use of the routefor aspecial event or holiday traffic may influence the final selection of a lane closure schedule. At some locations, a noise ordinance may conflict with lane closure schedules recommended in this LCS. If a potential to generate noise levels in excess of the limit allowed by the ordinance exists, the project manager may need to seek a variance.The RegionTrafficSectionplans to recalibrate the lane closure sch

Regionto monitor traffic continuously. Hourly volumes are available by direction for every day of the year. ATRs wereused to gather data covering the full calendar earfor the purposes of this LCSData from each of the TR locations were analyzed to evaluate variation in daily traffic levels over the course of the calendar year. The data indicated that the months of May through September weregenerally uniform relative to the other months of the year for most of the ATR locations. With consultation from the Region 4 Traffic Section, it was determined that these months would be categorized as the Spring/Summer Lane Closure season, and the months of April, May and October were added. The remaining months were categorized as the Fall/Winter season. Day of week variations were evaluated within these seasonal categories in a similar fashion, and it was determined that the da

Fridays were not included in the weekday data compilation because hourly patterns differ from other weekdays, particularly after noon. The higher of Saturday or Sunday daily traffic would represent the weekend. Region4 Lane Closure Strategy, 4 Ed. 6 Page Based on these categorizations, four factors were developed for each ATR location.Factors aremultiplied by the AADT volume to calculate the Average Daily Traffic (ADT) volume for a specific season and day of week. For example, the AADT along US northof Nunn(ATR#21) could be multiplied by 1.to calculate the Summer weekday ADTThisindicates that Summer weekdays carry percent more traffic than the annualaverage.

traffic volume information isavailable for at least one location on all state highways in Region. This information is primarily weekday counts taken during summer months (May through September). Some hourly distributions from previous LCS editions were carried over from the stEdition of the Region 4 LCS. These distributions are now over 10 years old and may not be reflective of current traffic conditions, especially the timing of peak periods. As a result, hourly volumes were compiledfor all segments that were reanalyzed in this edition in order to determine new hourly distributions.Analytical ProcedureTwo analytical procedures were developed to evaluate traffic characteristics throughout the system and to develop appropriate lane closure schedules. Freeways and multilane arterials have one set of capacity and operational characteristics since both directions can o

For such efforts, Figureoutlines the procedure for implementing a lane closure.Lane Closures for Design ProjectsAllowed lane closure hours are typically outlined in the specifications for CDOT design projects. The procedure for using the LCS to identify these hours is outlined in Figure . The procedure also includes steps for modifying the closure hours if needed.Unique circumstances may warrant modification(s) to the basic closure schedule. These unique circumstances might include, but are not limited to, the following: Temporary lane closures necessitated by publi

c safety emergencies supersede the hours outlined in this LCS. Nighttimetemperatures, noise restrictions(based on adjacent land use or town ordinances)materials supply limitations, etc. Nature of construction activity, for example, blasting may only be done during daylight hours. Seasonal or special events Potential restrictions for oversize vehicles. A work week is typically considered to be from Sunday at 9 PM to Friday at noon.Lane Closure Variances During ConstructionUpon implementing closure hours, it may be determined that an adjustment in the lane closure schedulis needed during construction. Figure outlines the procedure for changing the closure hours during construction.Lane closures may require variancesfor avariety of reasons. Typicalreasons for variance requests include: Chip Seals:Due to the short time frame for implementation, the need for higher dayti

19 me temperatures, and the need for higher
me temperatures, and the need for higher daytime traffic volumes to compact the product. Construction/Maintenance Activities:Due to particular techniques and/or projects that may require more continuous hours of lane closure than are possible given the restricted hours Alternate Routes:Due to the availability of multiple alternate routes and/or detours that can potentially lower traffic volumes and allow for expanded lane closure schedules. Nightwork Restrictions:Due to municipal noise ordinances that restrict night work and/or the operation of material plants at night. Variance RequestsVariance requests must be submitted to the RegionTraffic Section and should, at a minimum, include: The location and limits of the state highway lane closure A reiteration of the restricted hours in the Lane Closure Strategy A presentation of the requested change to the restrictedho

All freeways are four or more lanes wide and are divided highways with controlled access and grade separated interchanges only. The freeway analysis methodology was developed to address closure conditions unique to these roadways.Data Collectionand SynthesisTraffic data for I25, I70, and Iwere gathered from ATR information as well as individual spot counts from the CDOT OTIS database.As shown in Table , CDOT maintains three ATR locations on I25, two locations on I70, and two on I76. ATR data was used to develop seasonal and dayofweek factors, while spot counts provided segment AADT, truck volumes, and hourly distributions. All these tools were used to calculate hourly traffic volu

mes for each freeway segment.Analysis MethodologyDelay ThresholdThe approach used to determine appropriate lane closure schedules for freewaysegments consisted of comparing traffic demand with roadway capacity. The closure of a lane on a freewaysegment reduces roadway capacityand can create a bottleneck for traffic. To determine when a lane closure along a freewaysegment would be appropriate, it is necessary to determine times of day at which a lane closure would reduce the roadway capacity to a point where demand would exceed capacity, creating a bottleneck and causing delay to vehicles. Times during which the implementation of a lane closure induced an average vehicle delay in excess of 10 minutes for the duration of the bottleneck are eliminated as potential closure times. For these analyses, delay was defined asthe increase in travel time encountered during a la

23 ne closure compared to the estimated tra
ne closure compared to the estimated travel time during freeflowconditions.The average delay value of 10 minutes per vehicle was selected as a suitable delay threshold based on a review of prevalent practices around the country and internal discussions within CDOT. An average delay value of 10 minutes per vehicle provides an appropriate balance between delays to the traveling public and the cost of construction and maintenance.Lane closures implementedin accordance with the allowablehours included in this strategy are anticipated to cause delay for drivers. The effects of this delay, however, would be softened by the availability of alternate routes and detours to get around the closed portion of roadway. By including delay tolerances in these calculations, the restricted hours in the LCS account for the presence ofalternate routes and detours.Capacity ValuesThe clo

sure of a lane along a freeway segment causes a reduction in roadway capacity. In order to determine when a lane closure along a mainline freeway segment would be appropriate, it is necessary to determine times of day at which a lane closure would reduce the roadway capacity to a point where closure delay exceeds 10 minutes. A lane closurewould not be allowed during such times. When adequate capacity to accommodate demand exists even with the closure ofa lane, a lane closure is allowed.Typical freeway lane capacity varies between approximately 1800 vehicles per hour per lane (vphpl) and300 vphpl. Mainline freeway traffic volumes recorded in the Denver area have indicated that lane capacity can be as high as 2500 vphpl. The introduction of a lane closure to a mainline freeway segment Region4 Lane Closure Strategy, 4 Ed. 14 Page would be expected to reduce thi

s typical capacity by distracting drivers and shifting lane alignments, among other factors. Research conducted by Krammes and Lopez (Transportation Research Record 1442, 1994 pp. 4956) cited in the Highway Capacity Manual 2010 (HCM 2010) (2010 Edition, Transportation Research Board, p. 1026) indicates that the perlane capacity of a freeway facility is reduced when a lane closure is initiated. In the research, several freeway lane closure locations were studied to evaluate the capacity under closed conditions. It was found that, on average, the capacity of a mainline freeway segment with a lane closed is 1600 vphpl.Studies by the California Department of Transportation (CalTrans) and CDOT Region 2 indicate that freeway capacity during a lane closure depends upon the type of work being completed. Paving and milling operations have a much lower capacity than other typ

es of construction activities. To develop conservative allowed closure hours for this Strategy, a lane closure scenario was analyzed for freeways based on a paving operation. The lane closure capacity of a mainline freeway facility is 1100 vphpl when performing paving or milling operations. A delay threshold of 10 minutes was used for freeway segments. If the average delay with a lane closure exceeded this threshold a lane closure would not be allowed during that time period. The hourly traffic volumes along each section of mainline freeway were compared by direction with the estimated laneclosed capacity to determine an appropriate schedule for lane closures.Sequential freewaysegments with identical characteristics, such as number of lanes, grade, and direction, should all have the same capacity, even though they may serve different traffic volumes. In these instan

ces, the capacity of all the sequential segments is dictated by the segment that has the highest counted hourly volume.Freeway AnalysisA spreadsheet implementation of arrival / departure curves was formulated to automate the calculation of average delay induced by a lane closure along each multilanehighway section. The spreadsheet enables the user to choose lane closure schedules with average delay values less than 10 based on calculated hourly traffic volumesnitial closure scheduleswere selectedthat have the fewest restricted hours while providing the smallest average delay during closure. Additional adjustments were made to these schedules to provide at least two consecutive hours of closure or restriction. This allows meaningful construction/maintenance activity to be completed or excess vehicle queues to clear.Transportation Engineering literature documents the

use of arrival and departure curves to calculate vehicle delays and queues. The methodology outlined in the book Fundamentals of Traffic Engineering(May 1990, pp. 346349) uses a plot depicting cumulative vehicle arrivals at and departures from a given location over the course of 24 hours. For this analysis, the 24hour traffic count information was used to plot cumulative arrivals, and the roadway vehicle capacities discussed previously were used to formulate cumulative departure curves.Figure provides a sample plot of arrivals and departures. This plot corresponds to a particular direction of a state highway segmentbetween the hours of 8:00 AM and 2:00 PM on a typical weekday. The curves become separated whenthedemandarrival rate, represented by the blue curveexceeds capacity, creating oversaturated conditions. The departure rate, represented by the red curve,is red

uced to the capacity of the partially closed highway between 9:00 AM and 12:00 PM. The curves reconnect when capacity is sufficient to meet the demand. This can occur if the vehicle arrival rate decreases(demand is reduced)or if the capacity of the highway increases (the closed lane is reopened). In the sample plot shown on Figure , this occurs at 1:00 PM. Region4 Lane Closure Strategy, 4 Ed. 15 Page At any point, the delay of an individual vehicle can be identified graphically as the horizontal distance between the arrival (blue) and departure (red) curves. As shown on Figure , the number of vehicles that experience delay is represented by the vertical distance between the curves. The shaded area between the curves is the total delay in vehiclehours. The average delay can be calculated by dividing this area by the number of vehicles serviced during the perio

An average delay is calculated for each oversaturated period. this average delay remainsbelow 10 minutes, theclosure is allowed. As shown on Figure , the calculated delay resulting from the sample case is 6 minutes per vehicle.Freewaynalysis ResultsThe lane closure schedule tables in Appendix Appendix , and Appendix present, in detail, allowableclosure hours for all freeway segmentsin RegionFreeway segments have been divided at interchanges where significant AADT changes occur or where lane geometry changes Region4 Lane Closure Strategy, 4 Ed. 17 Page IV.MultiLane Highway AnalysisThe multilane analysis methodology was developed to create lane closure schedules for state highway segments within the egion that consist of t

The ATR data was used to develop seasonal and dayofweek factors, while spot counts provided segment AADT, truck volumes, and hourly distributions. All these tools were used to calculate hourly traffic volumes for each multilane arterial highway segment.Some segments did not have ATR locations to determine seasonal and dayofweek factors. Data from a nearby ATR was used as a representative.Weekend hourly

Segments without ATRs were assigned to nearby ATRs to determine a weekend hourly distribution.Analysis MethodologyDelay ThresholdAs with the FreewayAnalysis procedure, the closure of a lane on a multilane highway segment reduces roadway capacityand can create a bottleneck for traffi. To determine when a lane closure along a multilane highwaysegment would be appropriate, it is necessary to determine times of day at which a lane closure would reduce the roadway capacity to a point where demand would exceed capacity, creating a bottleneck and causing delay to vehicles. Times during which the implementation of a lane closure induced an average vehicle delay in excess of 10 minutes for the duration of the bottleneck are eliminated as potential closure times.

Many factors influence the perlane capacity of a multilane highway, including the composition of vehicular traffic and the green time allocated to the highway at signalized intersections Region4 Lane Closure Strategy, 4 Ed. 18 Page According to the HCM, the “ideal saturation flow rate” for an arterial facility is 1,900 passenger cars per hour per lane (pcphpl). Research conducted by the Denver Regional Council of Governments on saturation flow rates throughout the Denver metropolitanarea concludes that 1,900 pcphpl is an appropriate value for multilane highwaysunder typical operating conditions and can also be used for multilane highways in other parts of th

e state. This ideal flow rate is reduced to account for factors such as the presence of heavy vehicles in the traffic stream and signalized intersections. Accounting for these factors, the HCM estimates that the capacity of a typical arterial facility is 850 vphpl (vehicles per hour per lane).Therefore, an estimated capacity of 850 vphpl was used as a baseline capacity assumption for the development of thisLCS.This capacity, however, was adjusted upward in some cases to account for locations where the state highway facility is given a greater than typical allocation of green time. Such a condition is reflected in the traffic count information when the counted traffic volume at a given location exceeds 850 vphpl. At locations where the actual counted traffic volume exceeded 850 vphpl, the capacity value was adjusted upward to reflect the counted traffic volume.Sequen

Highwaysegments have been divided at intersectionswithsignificant AADT changes or locations where lane geometry changes Region4 Lane Closure Strategy, 4 Ed. 20 Page experience with flagging operations on Colorado projects supported capacity values similar to the ODOT values.Providingthe capacity values in Passenger Car Equivalents (PCE) allowed the specific inclusion of truck percentages in lane closure schedule calculations.Based on information in the HCM, a PCE of 1.5 or 2.5 was assigned to each 2lane highway in Region 4. The highe

r PCE of 2.5 was assigned to segments carrying and AADT of more than 5,000 vehicles per day and/or at least 10 percent trucks, which comprises the majority of 2lane segments within the west portion of Region 4.The PCE of 1.5 was assigned to 2lane highways carrying below 5,000 vehicles per day and less than 10 percent trucks. Oregon DOT guidance states that higher PCE values are appropriate for roadways carrying higher truck percentages and/or roadways on hilly terrain.AnalysisMethodologyTo identify allowable lane closure hourson twolane highways, hourly PCE volumes were determined for each highway segment and compared to the hourly capacity for each closure length category. spreadsheet implementation of 0.5mile, 1mile, and 3.0mile closure capacities was formulated to automate the calculation of hourly capacities. The spreadsheet enables the user to input an hourly d

This procedure was followed for both weekday and weekend volumesin Spring/ummer and Fall/Winter seasons. The result of the calculations can indicate that specific times should be restricted from lane closures or that no restrictions are applicable.Lane Analysis ResultsThe lane closure schedule tables in Appendix Appendix , and Appendix present, in detail, allowable closure hours for all twolane highwaysegments in Region4. Highwaysegments have been ivided at locationswhere significant AADT changes occur or where lane geometry changesSections were divided where lane geometry changes or daily traffic volumes changesignificantly. It is important to note that some sections are shorter than the closure le

41 ngths of0.5, 1.0, and 3.0 miles. When pr
ngths of0.5, 1.0, and 3.0 miles. When proposed lane closures will overlap such sections, it isrecommended that the segment with the fewest hours available for closure be implemented. Region4 Lane Closure Strategy, 4 Ed. 21 Page VI.Adjustments to Allowable Lane Closure HoursPer the request of Region 4 Staff and based on review comments received from CDOT and local agency representatives, some allowed closure hours were manually adjusted to reflect particular conditions and ensure consistency. Adjustments made included allowing or disallowing closures during particular time periods or closure lengths. These adjustments included: All lane closures along I25 south of the Mountain Vista Drive Interchange should be allowed at night only, beginning no earlier than 9 PM and ending no later than 5 AM. sures along the Diagonal Highway (SH 119 between Boulder and Longmo

42 nt) and SH 157 should only be allowed du
nt) and SH 157 should only be allowed during nonpeak hours All lane closures along US 287 through Old Town Fort Collins (Laurel Ave to Mountain Ave) should be allowed at night only, beginning no earlier than 9 PM and ending no later than 5 AM. All state highwayin Estes Park should only be closed at night during the Spring/Summer season. All state highways within Greeley, Loveland, Longmont, and Boulder should only be closed during nonak hours during the Spring/Summer season. Region4 Lane Closure Strategy, 4 Ed.
