WIM #37 I-94, MP 200.1 OTSEGO, 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 just uses the data that was collected for the month, no extrapolation. VOLUME WIM #37 on I-94 is located at mile post 200.1 in Otsego. The WIM is only on the westbound (WB) side of I-94. There were 729,902 vehicles that passed in the WB direction for the month of January. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) for the WB side in January 2012 were 23,545 and 3,234, respectively. Of the heavy commercial vehicles, the top two in volume were the Class 9’s and Class 5’s. Figure 1 shows the average number of vehicles versus the day of the week. The average numbers of vehicles peaked on Fridays and were lowest on weekends. Figure 2 shows the passenger vehicles (Class 1, 2, and 3), and heavy commercial vehicles (Class 4 to 13) by lane versus hour of day. For January 2012, the WB passenger vehicles peaked between 3 pm and 6 pm. The passenger vehicles were reviewed for volume differences between lanes and surprisingly there were more passenger vehicles in the passing lane than in the driving lane. For January 2012, the WB heavy commercial vehicles had a peak between 9 am and 3 pm. The heavy commercial vehicles were reviewed for volume differences between lanes and over 86% of the heavy commercial vehicles were in the driving lane. VEHICLE CLASSIFICATION The monthly traffic volume consisted of 629,640 passenger vehicles (86.3%) and 100,262 heavy commercial vehicles (13.7%). 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 #37 the Winter Load Increases (WLI) went into effect on January 21st, 2012. 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 56,100 pounds; and the maximum GVW is 88,000 pounds. The data was analyzed with the normal limits in effect up to January 21st and then the WLI after January 21st and that data is presented in the tables and graphs.

The total volume and total heavy commercial volume for January 2012 was 729,902 and 100,262, respectively. The total number of vehicles that were overweight was 10,692 or 1.5% of the total traffic or 10.7% of the heavy commercial vehicles. Figure 1 shows the average number of overweight vehicles versus day of the week. The average numbers of overweight vehicles for WB peaked on Wednesdays and were lowest on the 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 peaked from 10 am to 3 pm. Figure 4 shows the total overweight vehicles versus hour of the day. Comparing Figures 3 and 4 it is evident that the overweight Class 9 vehicles greatly affect the total number of overweight vehicles. Figure 4 also shows that for January 2012, over 91% of the overweight vehicles are in the driving lane as compared to the passing lane. Chart 1 shows the number of vehicles that crossed the WIM that weighed more than 88,000 pounds for the last 12 months. Although the chart is missing data from March through August 2011, it shows that there were a large number of overweight vehicles in February 2011. Figure 5 shows the gross vehicle weight for Class 9’s, 10’s, and 6’s. From Figure 5 it is apparent that the Class 6’s had more empty than full vehicles and the Class 9’s and 10’s had more full than empty vehicles. 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 WB direction during the normal load limits there were 527 vehicles over 88,000 pounds, 343 were Class 9’s and 84 were Class 10’s. In the WB direction during the WLI there were 238 vehicles over 98,000 pounds, 164 were Class 9’s and 38 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 2012. SPEED The speed limit on I-94 at the WIM site is 70 mph. For January 2012 for both WB lanes, WIM #37 recorded an average speed of 70 mph, the median speed was 71 mph, and the 85th percentile speed was 75 mph. Table 3 summarizes the vehicle data for the Top 20 speeders that crossed WIM #37 in the month of January. The speed of the Top 20 ranged from 94 mph up to 115 mph. Figure 6 shows the average speed of passenger vehicles and heavy commercial vehicles in both the WB driving and passing lane. As expected the slowest vehicles are the heavy commercial vehicles in the driving lane and the fastest vehicles are the passenger vehicles in the passing lane. Depending on the hour of the day there is between a 6 and 8 mph difference between the average slowest vehicles and the average fastest vehicles. Figure 7 shows the average speed versus the day of the week.

For January 2012 the average speeds generally varied between 64 mph and 72.5 mph. Figure 8 shows the average speed by lane. The WB passing lane was consistently about 3 to 4 mph faster than the driving lanes. BRIDGE Bridge No. 86817 is approximately 1.2 miles east of WIM #37 and Bridge No. 86813 is approximately 4.7 miles west of WIM #37. For the month of January 2012, WIM #37 saw 729,902 vehicles and measured a total weight of 6,860,000 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 2012 a total of 81,338 ESALs passed over the pavement on WB I-94 at WIM #37. Approximately 85.7% (69,716) of the ESALs were in the driving lane. 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 83.7% of the ESALs while they are only 54.7% 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 2 lanes for January 2012, the largest number of ESALs is in Lane 1, the WB driving lane. Therefore, the design lane would be the WB driving lane and the growth factor for this section of I-94 in Wright County is 2.9%. From January 1st to 20th for the NB lane, there were 2,640 Class 9 trucks and 401 Class 10 trucks over 80,000 pounds. These 3,041 vehicles generated 10,905 ESALs. If all of these trucks weighed just 80,000 pounds they would have generated 7,601 ESALs, 3,303 ESALs lower. From January 22nd to the end of the month for the NB lane, there were 247 Class 9 trucks and 86 Class 10 trucks over 88,000 pounds. These 333 vehicles generated 2,359 ESALs. If all of these trucks weighed just 88,000 pounds they would have generated 1,162 ESALs, 1,197 ESALs lower. If you take the January WB driving lane ESALs of 69,716 and multiply it by 12 to get an annual ESAL number, apply a growth factor of 2.9% for 20 years (1.58) and then multiply it by 20 to get a 20-year BESAL you get 26,436,000. If you go through the same process but start with a monthly value of 65,216, i.e. subtracting out all of the overweight Class 9 and 10 vehicles, you come up with 24,730,000 20-year BESALs. If you take the difference between the 20-year BESAL and divide that by 69,716, the BESALs with the overweight Class 9’s and 10’s you get 24.48, or the overweight Class 9’s and 10’s cause the pavement to reach its 20-year design life over 2 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 weight of freight we will add additional legal-weight trucks so that the total weight being shipped stays the same. FREIGHT For WIM #37 for January 2012, it was calculated that approximately 1,047,000 tons of freight crossed the sensors going WB on I-94. 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 and tonnage. CALIBRATION Because of the unique location of WIM #37 at MnROAD the test truck passes over the system every few weeks when it goes to get fuel. Because there were sensor failures and difficulties with communicating with the controller, calibration of WIM #37 did not occur until November 28, 2011. 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. 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 for both Classes and for both Lanes were within the range. In Table 8, the front axle weight for all three Classes in both lanes is currently within the range. Past WIM research indicates that an unloaded Class 9 should weigh 28 to 32 kips. Data from this 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 and 15 shows histograms of the monthly GVW of Class 9’s for the last 12 months for Lanes 1 and 2, respectively. Figure 16 is a graph of the unloaded and loaded peaks by lane versus date. There are enough Class 9’s in Lanes 1 and 2 that a semiweekly histogram can be developed. Both Lanes were recalibrated on November 28, 2011 and are remaining within range. SUMMARY For January 2012, the average volume for WB I-94 peaked on Fridays. The overweight vehicles peaked on Wednesdays and were lowest during the weekend. The overweight vehicles peaked from 10 am to 4 pm. For January 2012, for the Class 9’s, 9.3% of them were overweight, and for the Class 10’s, 73.3% of them were overweight. It appears that there are slight differences in speeds based on vehicle class, lane, and hour of the day. As expected, the GVW was higher in the driving lane versus the passing lane, 5,047,000 and 1,812,000; respectively. Also as expected, the ESALs were higher in the driving lane versus the passing lane, 69,716 and 11,622, respectively. For January 2012 approximately 1,047,000 tons of freight was shipped WB on I-94 at WIM #37. For January the overweight Class 9’s and 10’s were shortening the 20-year BESAL design
