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 November 2010, the system was operating normally. The data in this report uses the data that was collected for the month, no extrapolation. VOLUME For WIM #39 on MN 43 at mile post 45.2 in Winona, there were 316,242 vehicles that passed the site for the month of November. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) for November 2010 was 10,566 and 762, 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 northbound (NB) and southbound (SB) peaked on Fridays. 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 November the SB passenger vehicles had a peak between 7 am and 8 am and the NB passenger vehicles had a larger peak between 2 pm and 6 pm. The passenger vehicles were reviewed for directional volume differences and it appears that there is less than 0.6% difference. For November the NB heavy commercial vehicles had a peak between 7 am and 5 pm and the SB had a peak between 7 am and 5 pm and it appears that there are more heavy commercial vehicles going in the NB direction. VEHICLE CLASSIFICATION The traffic volume consisted of 293,429 passenger vehicles (92.8%) and 22,813 heavy commercial vehicles (7.2%). Table 1 summarizes vehicle class volumes and percentages; and overweight vehicles and the percentages as compared to total overweight vehicles. OVERWEIGHT VEHICLES Without a permit, the 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 total volume and total heavy commercial volume for November 2010 was 316,242 and 22,813, respectively. The total number of vehicles that were overweight was 5,076 or 1.6% of the total traffic or 22.3% 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 NB peaked on Mondays and for SB they peaked on Wednesdays and were lowest on weekends for both directions. The top two overweight violators by class were the Class 9’s and the Class 7’s. Overweight vehicles by class versus hour of the day are shown in Figure 3. The Class 9 overweight vehicles peaked between 6 am and 3 pm. The overweight vehicles were also reviewed to determine if there is a NB and SB difference. Figure 4 shows the total, NB, and SB overweight vehicles versus hour of the day. For November 2010, the peak time for overweight

2 | P a g e

vehicles was 7 am to 3 pm. Approximately, 1.4 times as many of the overweight vehicles were moving SB as compared to NB. Figure 5 shows the gross vehicle weight for Class 9’s and 10’s in both the NB and SB direction. From Figure 5 for Class 9’s, it is apparent that there are more full than empty going SB and more empty than full going NB. There are so few Class 10’s that it is hard to detect a trend. 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). With an accuracy of about 10% anything over a GVW of 88,000 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 NB direction there were 54 vehicles over 88,000 pounds, 51 were Class 9’s and 1 was Class 10. In the SB direction there were 50 vehicles over 88,000 pounds, 50 were Class 9’s and there were no Class 10’s. Table 2 summarizes the Top 10 Gross Vehicle Weight for Class 9 and Class 10 vehicles for the month of November 2010. SPEED The speed limit on MN 43 at the WIM site is 50 mph. For NB the speed limit goes up from 40 mph to 50 mph less than 0.2 miles from the WIM. For SB the speed drops from 50 mph to 40 mph less than 0.2 miles from the WIM and then to 30 mph in another 0.4 miles. For November 2010 for both lanes, WIM #39 recorded an average speed of 48 mph, the median speed was 48 mph, and the 85th percentile speed was 52 mph. Table 3 summarizes the vehicle data for the Top 20 speeders that crossed WIM #39 in the month of November. The speed of the Top 20 ranged from 70 mph to 105 mph. Figure 6 shows the average speed of passenger vehicles and heavy commercial vehicles in both the NB and SB direction. The fastest vehicles were the NB heavy commercial vehicles, probably due to the downgrade coming off Bridge No. 5900. Depending on the hour of the day there is a 1 to 2 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 November 2010, the average speeds varied between 47 mph and 51 mph. The daily variation that was seen in previous months is not reflected in the November data. Figure 8 shows the average speed by direction. The NB traffic is mostly the same speed as the SB traffic. BRIDGE Bridge No. 5930 is approximately 0.1 miles north of WIM #39, and Bridge No. 5900 is 0.3 miles south of WIM #39. For the month of November 2010, WIM #39 saw 316,242 vehicles and recorded a total weight of 1,931,000 kips (1 kip = 1,000 pounds). Figure 9 summarizes the total GVW by direction and class and Figure 10 summarizes the percentages each class contributes to the total GVW. Table 4 provides details on the class breakdowns versus direction for GVW.

MATERIALS For November 2010 a total of 18,540 ESALs passed over the pavement at WIM #39. Approximately 60.8% of the ESALs were SB and 39.2% were NB. Figure 11 graphically depicts the total ESALs by class and direction. 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 83.6% of the ESALs while they are only 32.2% of the total gross vehicle weight. Table 5 provides details on the class breakdowns versus direction 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 November 2010, the larger is Lane 2, the SB lane. Therefore, the design lane would be the SB lane and the growth factor for this section of MN 43 in Winona County is 1.1%. For November there were 407 Class 9 trucks and 3 Class 10 trucks over 80,000 pounds in the SB lane. These 410 vehicles generated 1,299 ESALs. If all of these trucks weighed just 80,000 pounds they would have generated 1,099 ESALs, 200 ESALs lower. If you take the November SB lane ESALs of 11,274 and multiply it by 12 to get an annual ESAL number, apply a growth factor of 1.1% for 20 years (1.22) and then multiply it by 20 to get a 20-year BESAL you get 3,301,000. If you go through the same process but start with a monthly value of 11,074, i.e. subtracting out all of the overweight Class 9 and 10 vehicles, you come up with 3,242,000 20-year BESALs. If you take the difference between the 20-year BESAL and divide that by 11,274, the BESALs with the overweight Class 9’s and 10’s you get 5.2, or the overweight Class 9’s and 10’s cause the pavement to reach its 20-year design life about 5 months 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 #39 for November 2010, it was calculated that approximately 97,000 tons of freight crossed the sensors. More freight was shipped SB (64,000 tons) versus NB (33,000 tons). Table 6 summarizes 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 #39 was calibrated on October 14, 2010. The calibration results are included at the end of the report. 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%. The initial values after calibration on October 14 are shown in Tables 7 and 8. As you can see in Table 7, the GVW was outside the range of ±5% for both Classes in Lane 1 and Class 3 in Lane 2. In Table 8 the front axle weight stayed within ±9% for all Classes in Lane 2 and was outside the range for all Classes in Lane 1. 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 and 15 shows histograms of the monthly GVW of Class 9’s for the last 10 months for Lanes 1 and 2. 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 semimonthly histogram can be developed. With a little less than 2 months of data since the system was last calibrated, so far the SB lane at WIM #39 is working fine and is staying in the calibration range. The winter calibration is scheduled for the end of January. The winter calibration should fix the issue with Lane 1. SUMMARY For November 2010 the average volumes peaked on Fridays in both directions. The overweight vehicles peaked on Mondays for NB and on Wednesdays for SB and were lowest on the weekends in both directions. The number of overweight vehicles was 1.4 times higher for SB as compared to NB. The overweight vehicles peaked from 7 am to 3 pm. For November 2010, for the Class 9’s, 28.0% of them were overweight and for the Class 10’s, 47.1% of them were overweight. The speed of the traffic did not vary significantly based on vehicle class, lane, hour of the day, or day of the week. The GVW was higher in the SB direction 1,013,000 kips versus 918,000 kips NB. This agrees with the ESALs and freight data. The SB ESALs were higher 11,274 versus 7,266 NB. The tonnage of freight was also higher in the SB direction 64,000 versus 33,000 NB. For November, the overweight Class 9’s and 10’s were shortening the 20-year BESAL design life by 5 months. Table 9 provides a monthly summary of some of the key data for the site during 2010.
