WIM #35 US 2, MP 91.8 BAGLEY, MN JANUARY 2012 MONTHLY REPORT

1 | P a g e

In order to understand the vehicle classes and groupings the Mn/DOT “Vehicle Classification Scheme” and the “Vehicle Class Groupings for Forecasting” are shown on the WIM Reports home page at http://www.dot.state.mn.us/traffic/data/html/wim_reports.html For the month of January 2012, the system was operating normally. The data in this report uses the data that was collected for the month, no extrapolation. VOLUME For WIM #35 on US 2 at mile post 91.8 near Bagley, there were 144,629 vehicles that passed the site for the month of January. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) for January 2012 was 4,665 and 501, respectively. Of the heavy commercial vehicles, the top two in volume were the Class 9’s, and 5’s. Figure 1 shows the average number of vehicles, broken down by direction, versus day of the week. The average numbers of vehicles for eastbound (EB) and westbound (WB) peaked on Fridays and was lowest on Sundays. Figure 2 shows the passenger vehicles (Class 1, 2, and 3), and heavy commercial vehicles (Class 4 to 13) by direction versus hour of day. For January the EB passenger vehicles peaked between 3 pm and 6 pm. The WB passenger vehicles had a similar peak but between 2 pm and 6 pm. The passenger vehicles were reviewed for directional volume differences and it appears that there are slightly more vehicles going WB. For January the EB heavy commercial vehicles had a peak between 10 am and 1 pm and WB heavy commercial vehicles had a peak between 7 am and 11 am. There were 70% of the heavy commercial vehicles going EB. VEHICLE CLASSIFICATION The traffic volume consisted of 129,086 passenger vehicles (89.3%) and 15,543 heavy commercial vehicles (10.7%). Table 1 summarizes vehicle class volumes and percentages; and overweight vehicles and the percentages as compared to total overweight vehicles. OVERWEIGHT VEHICLES In the area of WIM #35 the Winter Load Increases (WLI) went into effect on December 26, 2011. The normal maximum allowable weight for a single axle is 20,000 pounds; tandem axles, spaced 8’ or less, can be up to 34,000 pounds; tridem axles, spaced 9’ or less, can be up to 43,000 pounds; quad axles, spaced 13’ or less, can be up to 51,000 pounds; and the maximum GVW is 80,000 pounds. The WLI allows a 10% across the board increase in axle and gross vehicle weights (GVW) without a permit on US, state routes, and county roads. A permit is required to operate on the interstate at the WLI levels. The WLI means that the maximum allowable weight for a single axle is 22,000 pounds; tandem axles, spaced 8’ or less, can be up to 37,400 pounds; tridem axles, spaced 9’ or less, can be up to 47,300 pounds; quad axles, spaced 13’ or less, can be up to 56,100 pounds; and the maximum GVW is 88,000 pounds. The data was analyzed with the WLI during January and that data is presented in the tables and graphs.

The total volume and total heavy commercial volume for January 2011 was 144,629 and 15,543, respectively. The total number of vehicles that were overweight was 1,588 or 1.1% of the total traffic or 10.2% of the heavy commercial vehicles. Figure 1 shows the average number of overweight vehicles, broken down by direction, versus day of the week. The average numbers of overweight vehicles for EB peaked on Wednesdays and for WB it peaked on Wednesdays and for both directions they were lowest on weekends. The top two overweight violators by class were the Class 9’s and the Class 10’s. Overweight vehicles by class versus hour of the day are shown in Figure 3. The Class 9 overweight vehicles had multiple peaks but generally peaked between 11 am and 5 pm. The Class 10 overweight vehicles peaked at lower volumes and between 10 am and 4 pm. The overweight vehicles were also reviewed to determine if there is an EB and WB difference. Figure 4 shows the total, EB, and WB overweight vehicles versus hour of the day. Figure 4 shows that for January 2011, over 76% of the overweight vehicles were in the EB direction. Figure 5 shows the gross vehicle weight for Class 9’s and 10’s in both the EB and WB direction. From Figure 5 it is apparent that the Class 9’s had more empty than full vehicles going EB and WB. The Class 10’s had more full vehicles than empty vehicles going EB and more empty than full vehicles going WB. Chart 1 shows the number of vehicles during the last 12 months that crossed the WIM weighing more than 88,000 pounds. From the chart, it can be seen that there were a large number of weight violations over 100,000 pounds most of them occurring in the months of January, February, November and December. This may have been caused by the WIM being out of calibration. For weight enforcement the WIMs are a screening tool. Currently, piezo-quartz WIM systems are considered to be accurate within 5% to 10% on Gross Vehicle Weight (GVW). During normal load limits and with an accuracy of about 10% anything over a GVW of 88,000 pounds is overweight. With the 10% WLI and accuracy of about 10% anything over a GVW of 96,800 pounds is overweight. These may still be permitted loads. For the most efficient use of personnel and equipment, these are the vehicles that should be weighed on static scales and reviewed for permits. In the EB direction during the WLI there were 665 vehicles over 98,000 pounds, 356 were Class 9’s and 284 were Class 10’s. In the WB direction during the WLI there were 21 vehicles over 98,000 pounds, none were Class 9’s and 8 were Class 10’s. Table 2 summarizes the Top 10 Gross Vehicle Weight for Class 9 and Class 10 vehicles for the month of January 2011. SPEED The speed limit on US 2 at the WIM site is 65 mph. For January 2011 for all four lanes, WIM #35 recorded an average speed of 65 mph, the median speed was 65 mph, and the 85th percentile speed was 70 mph. Table 3 summarizes the vehicle data for the Top 20 speeders that crossed WIM #35 in the month of January. The speed of the Top 20 ranged from 90 mph up to 113 mph. It is interesting to note that it looks like 2 in the Top 20 may have been racing. Two vehicles went over the sensors EB in Lanes 1 and 2 on Thursday, January 19th at 4:20:29 pm at the same time both going 93 mph. Figure 6

3 | P a g e

shows the average speed of passenger vehicles and heavy commercial vehicles in both the EB and WB direction by lane. As expected, generally the slowest vehicles are the heavy commercial vehicles in the driving lanes and the fastest vehicles are the passenger vehicles in the passing lanes. Depending on the hour of the day there is between a 3 and 8 mph difference between the average slowest vehicles and the average fastest vehicles. During the overnight hours the volume drops way off, which is why there are unusual dips and peaks during those times. Figure 7 shows the average speed versus the day of the week. For January 2011 the average speeds varied between 60 mph and 67.5 mph. There was not a significant variation in speed by day of the week. Figure 8 shows the average speed by lane. As expected, the passing lanes were consistently faster, about 2 to 5 mph, than the driving lanes. The variations very early in the morning are due to low volumes. BRIDGE Bridge No. 15X02, a box culvert, is approximately 5.3 miles east of WIM #35, and Bridge No. 15001 on the EB side and Bridge No. 15004 on the WB side are 2.6 miles west of WIM #35. For the month of January 2011, WIM #35 saw 144,629 vehicles with a total weight of 1,196,000 kips (1 kip = 1,000 pounds). Figure 9 summarizes the total gross vehicle weight (GVW) by lane and class and Figure 10 summarizes the percentages each class contributes to the total GVW. Table 4 provides details on the class breakdowns versus lane for GVW. MATERIALS For January 2011 a total of 16,550 ESALs passed over the pavement at WIM #35. Approximately 98.0% of the ESALs were in the driving lane, 75.8% EB and 22.2% WB. Figure 11 graphically depicts the total ESALs by class and lane. Figure 12 summarizes the percentages that each vehicle class contributes to the total ESALs. It is interesting to note that the Class 9’s provide 55.7% of the ESALs while they are only 25.5% of the total gross vehicle weight. Table 5 provides details on the class breakdowns versus lane for ESALs. Table 5 also provides the flexible ESAL factors for each vehicle class using a terminal serviceability of 2.5 and a structural number of 5. Reviewing the ESALs in the 4 lanes for January 2011, the largest number of ESALs is in Lane 1, the EB driving lane. Therefore, the design lane would be the EB driving lane and the growth factor for this section of US 2 in Clearwater County is 1.5%. In January for the EB driving lane, there were 475 Class 9 trucks and 309 Class 10 trucks over 88,000 pounds. These 784 vehicles generated 7,853 ESALs. If all of these trucks weighed just 88,000 pounds they would have generated 2,506 ESALs, 5,347 ESALs lower. If you take the January EB driving lane ESALs of 12,539 and multiply it by 12 to get an annual ESAL number, apply a growth factor of 1.5% for 20 years (1.30) and then multiply it by 20 to get a 20-year BESAL you get 3,912,000. If you go through the same process but start with a monthly value of 7,192, i.e. subtracting out all of the overweight Class 9 and 10 vehicles, you come up with 2,244,000 20-year BESALs. If you take the difference between the 20-year BESAL and divide that by 12,539, the BESALs with the overweight Class 9’s and 10’s you get 133.06, or the overweight Class 9’s and 10’s cause the pavement to reach its 20-year design life over 11 years early.

This is a quick, back of the napkin calculation, this only looks at Class 9’s and 10’s, not the other 8 heavy commercial classes. As part of a technical implementation research project we are looking at developing a report function that will perform this calculation for all heavy commercial classes. Because the heavy commercial haulers are looking to move that tonnage of freight we will add additional legal-weight trucks so that the total tonnage being shipped stays the same. FREIGHT For WIM #35 for January 2011, it was calculated that approximately 124,000 tons of freight crossed the sensors. More freight was shipped EB (79,000 tons) versus WB (45,000 tons). Table 6 summarizes the number of vehicles by class and the number of empty vehicles. Table 6 and Figure 13 summarize the freight shipment by class, direction, and tonnage. CALIBRATION WIM #35 was calibrated on January 18, 2012. As part of the on-going monitoring to assure the performance between calibrations, gross vehicle weights and front axle weights of Class 2’s, 3’s, and 9’s are being monitored on a monthly basis. Table 7 summarizes the gross vehicle weight of the Class 2’s and 3’s by lane. Currently, all Class 2’s and 3’s are included in this data. In the future, the goal would be to only monitor the Class 2’s and 3’s that are not pulling trailers. Table 8 summarizes the front axle weight of the Class 2’s, 3’s, and 9’s by lane. The current goal of the calibration is to first have the GVW for each class and each lane stay within a range of ±5% and then secondly to have each individual axle stay within a range of ±9%. As you can see in Table 7, the GVW was within the range of ±5% for both Classes in Lane 2 and Lane 2. In Table 8 the front axle weight was within the range of ±9% for all Classes in Lanes 2, 3 and 4, except for Class 9 Lane 3. February GVW and front axle weights will be used as initial settings next month. Past WIM research indicates that an unloaded Class 9 should weigh 28 to 32 kips. Data from the MnROAD site indicates that this unloaded range may have moved a little higher. The range for loaded Class 9’s is generally in the 70 to 80 kip range but varies more by site and season. Figures 14 to 17 shows histograms of the monthly GVW of Class 9’s over the last 11 months for Lanes 1 and 4 and over the last 14 months for Lanes 2 and 3. Figure 18 is a graph of the unloaded and loaded peaks by lane versus date. There are enough Class 9’s in Lanes 1 and 4 that a weekly histogram can be developed, while for Lanes 2 and 3 about two months of data is needed to develop a clear histogram. With only about 3 months of data since the last calibration, it looks like WIM #35 needs to be recalibrated, only Lane 4 seems to be performing well. Lane 1 is grossly out of range which may explain the large number of ESALs in Lane 1. The winter calibration for WIM #35 is scheduled for early February. January 18, 2012 calibration results are included in this report. SUMMARY For January 2011 the average volumes peaked on Fridays in both directions. The overweight vehicles peaked on Wednesdays EB and on Wednesdays for WB. Over 76%

5 | P a g e

of the average numbers of overweight vehicles were in the EB direction. The overweight vehicles peaked from 10 am to 4 pm. For January 2011, for the Class 9’s, 13.5% of them were overweight and for the Class 10’s, 31.1% of them were overweight. The speed of the traffic varies slightly based on vehicle class, lane, and hour of the day, but there was no significant difference in speed based on day of the week. The GVW was a little higher in the EB direction 677,000 kips versus 519,000 kips WB. This agrees with the ESALs and freight data. The EB ESALs were higher 12,832 versus 3,718 WB. The tonnage of freight was also higher in the EB direction 79,000 versus 45,000 WB. For January, the overweight Class 9’s and 10’s were shortening the 20-year BESAL design life by over 11 years.
