1 WIM #41 CSAH 14, MP 14.9 CROOKSTON, MINNESOTA MAY 2013 MONTHLY REPORT

2 In order to understand the vehicle classes and groupings the Mn/DOT Vehicle Classification Scheme and the Vehicle Classification Groupings for Forecasting are shown on the TDA Data Products page at The WIM Monthly Reports are show at For the month of May 2013, the system was operating normally. The data in this report uses the data that was collected for the month, no extrapolation. VOLUME For WIM #41 on CSAH 14 at mile post 14.9 south of Crookston, there were 13,701 vehicles that passed the site for the month of May. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) for May 2013 was 442 and 46, respectively. Of the heavy commercial vehicles, the top two in volume were the Class 5 s and 9 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 Thursdays and was lowest on the weekend for both directions. 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 May the NB passenger vehicles had a peak between 6 am and 8 am and the SB passenger vehicles had a peak between 2 pm and 6 pm. The passenger vehicles were reviewed for directional volume differences and it appears that there were more passenger vehicles going SB. For May the NB heavy commercial vehicles had a peak between 8 am and 5 pm and the SB having a peak between 7 am and 5 pm. The heavy commercial vehicles were reviewed for directional volume differences and it appears that there were more heavy commercial vehicles going SB. VEHICLE CLASSIFICATION The traffic volume consisted of 12,272 passenger vehicles (89.6%) and 1,429 heavy commercial vehicles (10.4%). Table 1 summarizes vehicle class volumes and percentages; and overweight vehicles and the percentages as compared to total overweight vehicles. OVERWEIGHT VEHICLES 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 gross vehicle weight (GVW) is 80,000 pounds. The total volume and total heavy commercial volume for May 2013 was 13,701 and 1,429, respectively. The total number of vehicles that were overweight was 186 or 1.4% of the total traffic or 13.0% 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 Thursdays and for SB peaked on Wednesdays and it was lowest on the weekends for both 1 P age

3 directions. The top two overweight violators by class were the Class 9 s and the Class 4 s. Overweight vehicles by class versus hour of the day are shown in Figure 3. Two different methods are being used to classify vehicles at the WIM. One system uses a first fit to classify the vehicles and the other uses a best fit method. With either method, the same number of axles, axle spacing, and axle weights are used. This is why there are some differences concerning the numbers of Class 9, 10, and 13 overweight vehicles. The overweight vehicles peaked between 11 am and 4 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. Over 64% of the overweight vehicles were going SB. 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 were more empty than full vehicles going both directions. For Class 10 s, it is apparent that there were more empty than full vehicles going NB and more full than empty vehicles going SB. 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 overweight violations in September through December 2012 and February For weight enforcement the WIMs are a screening tool. Currently, piezo-quartz WIM systems are considered to be 90% to 95% accurate on Gross Vehicle Weight (GVW). During normal load limits and with an accuracy of about 90% 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 during the normal load limits there were 21 vehicles over 88,000 pounds, all 21 were Class 9 s. In the SB direction during the normal load limits there were 7 vehicles over 88,000 pounds, all 7 were Class 9 s. Table 2 summarizes the Top 10 Gross Vehicle Weight for Class 9 and Class 10 vehicles for the month of May SPEED The speed limit on CSAH 14 at the WIM site is 55 mph. For May 2013 for both lanes, WIM #41 recorded an average speed of 60 mph, the median speed was 62 mph, and the 85 th percentile speed was 68 mph. Table 3 summarizes the vehicle data for the Top 20 speeders that crossed WIM #41 in the month of May. The speed of the Top 20 ranged from 86 mph to 99 mph. Figure 6 shows the average speed of passenger vehicles and heavy commercial vehicles in both the NB and SB direction. The heavy commercial traffic tended to be 4 to 6 mph slower. Figure 7 shows the average speed versus the day of the month. For May 2013 the average speeds generally varied between 50 mph and 67 mph. Figure 8 shows the average speed by lane/direction. For all three figures, some of the wider variation later at night or very early in the morning is due to the very low volume. 2 P age

4 BRIDGE Bridge No is approximately 0.1 miles north of WIM #41, and Bridge No. 60K60 is 3.2 miles south of WIM #41. For the month of May 2013, WIM #41 saw 13,701 vehicles and recorded a total weight of 112,000 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 May 2013 a total of 821 ESALs passed over the pavement at WIM #41. Approximately 481 (58.6%) of the ESALs were SB and 340 (41.4%) 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 51.9% of the ESALs while they are 18.4% 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 May 2013, the largest is Lane 2, the SB lane. Therefore, the design lane would be the SB driving and the growth factor for this section of CSAH 14 in Polk County is 1.5%. In May, for the SB driving lane, there were 33 Class 9 trucks and 3 Class 10 trucks over 80,000 pounds. These 36 vehicles generated 115 ESALs. If all of these trucks weighed just 80,000 pounds they would have generated 93 ESALs, 23 ESALs lower. If you take the May SB driving lane ESALs of 481 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 150,000. If you go through the same process but start with a monthly value of 458, i.e. subtracting out all of the overweight Class 9 and 10 vehicles, you come up with year BESALs. If you take the difference between the 20- year BESAL and divide that by 481, the BESALs with the overweight Class 9 s and 10 s you get 14.7, or the overweight Class 9 s and 10 s cause the pavement to reach its 20- year design life over 14 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 #41 for May 2013, it was calculated that approximately 9,500 tons of freight crossed the sensors. More freight was shipped SB (5,600 tons) versus NB (3,900 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. 3 P age

5 CALIBRATION WIM #41 was most recently calibrated on June 21, 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 was within the range for everything except the Class 2 s in Lane 1. In Table 8 the front axle weight was within the range for all three Classes in both Lanes. 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 12 months for Lanes 1 and 2. Figure 16 is a graph of the unloaded and loaded peaks by lane versus date. There are only enough Class 9 s in Lanes 1 and 2 that about a month of data is needed to develop a clear histogram. So far WIM #41 is working fine and is generally staying in the calibration range. SUMMARY For May 2013, the average volume peaked for NB and SB on Thursdays and was lowest on the weekends for both directions. The average numbers of overweight vehicles for NB peaked on Thursdays and for SB peaked on Wednesdays and it was lowest on weekends for both directions. Over 64% of the overweight vehicles were going SB. For May 2013, for the Class 9 s, 22.9% of them were overweight and for the Class 10 s, 9.6% of them were overweight. The speed of the traffic varied slightly based on direction and vehicle class with the heavy commercial vehicles consistently slower. The GVW was higher in the SB direction 59,000 kips versus 53,000 kips NB. This agrees with the ESALs and the freight data. The SB ESALs were higher 481 versus 340 NB. The tonnage of freight was higher in the SB direction 5,600 versus 3,900 NB. For May, the overweight Class 9 s and 10 s were shortening the 20-year BESAL design life by over 14 months. Table 9 provides a monthly summary of some of the key data for the site during the last 12 months.
