WIM #35 US 2, MP 91.8 BAGLEY, MN SEPTEMBER 2014 MONTHLY REPORT

1 | P a g e

In order to understand the vehicle classes and groupings, the MnDOT “Vehicle Classification Scheme” and the “Vehicle Class Groupings for Forecasting” are shown on the TDA Data Products page at http://www.dot.state.mn.us/traffic/data/data-products.html#weight. The WIM Monthly Reports are shown at http://www.dot.state.mn.us/traffic/data/reports-monthly-wim.html. For September 2014, the system appeared to be operational for the entire month. Upstream loops in Lanes 3 and 2 (respectively the WB passing lane and the EB passing lane) were disabled on Tuesday, 8/12 and Wednesday, 8/13. Since that time, C15 rates were generally within the typical range for this site (based on historical data) for this month. Volume was computed using all monthly data. VOLUME For WIM #35 on US 2 at mile post 91.8 near Bagley, there were 184,295 vehicles that passed the site for the month of September. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) were respectively 6,143 and 575 in September 2014. Of the heavy commercial vehicles, the two highest traffic volumes were generated by the Class 9’s and 5’s. Figure 1 shows the average number of vehicles broken down by direction (eastbound vs. westbound; EB vs. WB) and as a function of time (weekday). The average traffic volume of EB vehicles peaked on Fridays and was lowest on Sundays. Similarly, the average traffic volume of WB vehicles peaked on Fridays but was lowest on Saturdays. Figure 2 shows directional traffic volume for passenger vehicles (Classes 1, 2, and 3) and heavy commercial vehicles (Classes 4 to 13), as a function of time (hour of day). Volume peaked between 10:30 am and 6:30 pm for EB passenger vehicles, while volume peaked between 11:30 am and 7:00 pm for WB passenger vehicles. Data also showed that a greater proportion of passenger vehicles traveled WB than EB (51.2% WB, 48.8% EB). For heavy commercial vehicles, volume going EB peaked between 9:00 am and 6:30 pm, while volume going WB peaked between 6:00 am and 6:00 pm. Heavy commercial vehicles were also reviewed for directional volume differences; data showed that a greater proportion of heavy commercial vehicles traveled EB than WB (51.9% EB, 48.1% WB). VEHICLE CLASSIFICATION The traffic volume consisted of 167,057 passenger vehicles (90.6%) and 17,238 heavy commercial vehicles (9.4%). Table 1 summarizes traffic volumes by vehicle class, as well as providing traffic volume information for overweight vehicles. OVERWEIGHT VEHICLES During normal weight limits, 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 data were analyzed with the normal load limits in effect and that data is presented in the tables and graphs.

The total volume and total heavy commercial volume for September 2014 was 184,295 and 17,238, respectively. A total of 2,481 vehicles were overweight, which translates into 1.3% of the total traffic (or 14.4% of heavy commercial vehicles). Figure 1 shows the average number of overweight vehicles traveling directionally (EB vs. WB) as a function of time (weekday). The average number of overweight vehicles traveling EB peaked similarly across Tuesdays through Fridays, while volume for WB overweight vehicles peaked similarly from Tuesdays through Thursdays. Lowest volumes for overweight vehicles were observed over the weekends. The top two overweight violators by class were the Class 9’s and the Class 10’s. Figure 3 depicts overweight vehicles by class as function of time (hour of day). Class 9 overweight vehicles peaked between 7:00 am and 2:30 pm. The overweight vehicles were also examined for directional differences. Data shows that 52.8% of overweight vehicles were traveling WB. Figure 4 shows total volume of overweight vehicles as function of time (hour of day), with volumes also calculated by direction (EB vs. WB). Figure 5 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 the number of weight violations were highest over the previous winter months (particularly February 2014), after which time the numbers have generally declined. Figure 6 shows the gross vehicle weight distribution for Class 9’s and 10’s traveling both directions (EB and WB). Figure 6 illustrates that there were greater numbers of empty than full Class 9’s traveling in both the EB and WB directions. In contrast, there were greater numbers of full than empty Class 10’s traveling EB, while there were more empty than full Class 10’s traveling in the WB direction. WIMs are currently used as a screening tool for weight enforcement, and it is estimated that the WIM scales can measure gross vehicle weights (GVW) within 90-95% of static weight scales. Therefore, due to some measurement difference on the WIMs, vehicles that are over 88,000 pounds during normal load limits are considered overweight on this report1. For the most efficient use of personnel and equipment, these overweight vehicles should be weighed on static scales and reviewed for permits. During the normal load limits, 475 EB vehicles were over 88,000 pounds (15 vehicles were Class 9’s; 418 vehicles were Class 10’s). Of vehicles traveling WB during normal load limits, 96 vehicles were over 88,000 pounds (15 were C9’s; 56 were C10’s). Table 2 summarizes the Top 10 Gross Vehicle Weights for Class 9 and Class 10 vehicles for September 2014. SPEED The speed limit on US 2 at the WIM site is 65 mph. Combining all four lanes in September 2014, the following was recorded at WIM #35: 1) average speed of 67 mph, 2) median speed of 69 mph, and 3) an 85th percentile speed of 72 mph. Table 3

1 Vehicles are legally considered overweight at 80,000 pounds during normal load limits. However, to accommodate for the possibility of measurement error on the WIMs, vehicles weighing more than 10% over the legal overweight definition are considered overweight for the purposes of this report (> 88,000 pounds; 80,000 lbs + 8,000 lbs = 88,800 lbs).

summarizes the vehicle data for the Top 20 speeders that crossed WIM #35 in September. The speed of the Top 20 ranged from 98 mph to 119 mph. It is interesting to note that three vehicles in the Top 20 may have been racing. On Thursday, 9/18/14 at 1:37 pm, three WB vehicles crossed the WIM within seconds of each other at high speeds. Figure 7 shows the average speed of passenger vehicles and heavy commercial vehicles as a function of lane (Lanes 1 - 4), direction (EB vs. WB), and time (hour). The slowest vehicles were the heavy commercial vehicles in both driving lanes, while the fastest vehicles were the passenger vehicles in both passing lanes. There was approximately a 4 mph difference between the average slowest vehicles and the average fastest vehicles. Figure 8 shows the average speed as a function of the day of month. Depending on the hour of the day, the average hourly speeds varied between 63 mph and 71 mph over the course of the month. Figure 9 shows the average speed as a function of lane (Lanes 1 - 4). Vehicles in the passing lanes were, on average, 3 mph faster than vehicles in the driving lanes that were traveling in the same direction. 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 September 2014, WIM #35 encountered 184,295 vehicles with a total weight of 1,437,786 kips (1 kip = 1,000 pounds). Figure 10 summarizes the total gross vehicle weight (GVW) by vehicle class and lane, while Figure 11 summarizes the percentage each class contributes to the total GVW. Table 4 provides GVW values by vehicle class and lane. MATERIALS In September 2014, a total of 12,513 equivalent single axle loads (ESALs) passed over the pavement at WIM #35, with approximately 94.3% of the ESALs in the driving lane (42.0% EB and 52.3% WB). Figure 12 graphically depicts the total ESALs by vehicle class and lane. Figure 13 summarizes the percentages that each vehicle class contributes to the total ESALs. It is interesting to note that the Class 9’s provide 59.2% of the ESALs while they comprise only 27.2% of the total gross vehicle weight. Table 5 provides details on ESAL values by class and lane. 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. For September 2014, ESALs were largest in Lane 4 (WB driving lane). Therefore, the WB driving lane is the design lane, and the growth factor for this section of US 2 in Clearwater County is 1.5%. During the normal load limits, there were 637 Class 9 trucks and 85 Class 10 trucks weighing over 80,000 pounds in the WB driving lane. These 722 vehicles generated 2,018 ESALs. If all of these trucks weighed just 80,000 pounds they would have generated 1,819 ESALs—199 ESALs less. If you take September’s WB driving lane ESALs of 6,550 and multiply it by 12 to get an annual ESAL number, apply a growth factor of 2.5% for 20 years (1.50) and then multiply it by 20 to get a 20-year BESAL, you get 2,043,670. If you go through the same calculation but start with a monthly value of

4 | P a g e

6,351 (WB driving lane ESALs without all of the overweight Class 9 and 10 vehicles), you come up with 1,981,666 20-year BESALs. The difference between the 20-year BESALs, divided by 6,550 ESALs, is 9.47 months. This translates into the pavement reaching its 20-year design life about 9 months earlier due to the overweight Class 9’s and 10’s. This is a quick, back-of-the-napkin calculation specifically the Class 9’s and 10’s; calculation does not include the 8 other 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, it was calculated that 136,325 tons of freight crossed the sensors. More freight was shipped WB (70,377 tons) than EB (65,949 tons). Table 6 summarizes the number of vehicles by class and the number of empty vehicles. Table 6 and Figure 14 summarize the freight shipment by class, direction, and tonnage. CALIBRATION WIM #35 was most recently calibrated on June 24, 2014. Front axle weights of Class 2’s, 3’s, and 9’s are being monitored on a monthly basis to assure performance between calibrations. Table 7 summarizes the front axle weights of the Class 2’s, 3’s, and 9’s by lane. The current goal of the calibration is to have each individual axle weight stay within a range of ±9% of baseline calibration. Table 7 shows that the front axle weights were within ±9% of baseline calibration values for all three classes in all four 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 15 to 18 show histograms of the following: 1) monthly GVW of Class 9’s over the last 12 months for Lanes 1 and 4, and 2) monthly GVW of Class 9’s over the last 24 months for Lanes 2 and 3. Figure 19 depicts unloaded and loaded peaks as a function of lane (Lanes 1 - 4) and date. There are enough Class 9’s in Lanes 1 and 4 that a histogram can be generated weekly. In contrast, Lanes 2 and 3 do not get enough Class 9 traffic, meaning that an interpretable histogram can only be generated every 2 months. SUMMARY In September 2014, the average volume of EB and WB traffic both peaked on Fridays. The average number of overweight vehicles traveling EB peaked similarly across Tuesdays through Fridays, while volume for WB overweight vehicles peaked similarly from Tuesdays through Thursdays. Lowest volumes for overweight vehicles were observed over the weekends. Data also showed that just over half of all overweight vehicles (52.8%) traveled WB. Traffic volume for overweight vehicles peaked between 7:00 am and 5:30 pm. Of the Class 9’s, 15.3% of them were overweight, while 49.9% of

5 | P a g e

Class 10’s were overweight. The speed of the traffic varied slightly based on vehicle class, lane, and hour of the day. However, no significant differences in speed were observed based on day of the week. Overall GVW was greater in the WB direction than EB direction (732,872 kips vs. 704,914 kips). A similar pattern emerged for ESAL and freight data. WB ESALs were greater than EB ESALs (6,931 ESALs vs. 5,582 ESALs), and freight tonnage was also greater going WB than EB (70,377 tons vs. 65,949 tons). Data calculations from September 2014 also suggest that overweight Class 9’s and 10’s are shortening the 20-year BESAL design life by approximately 9 months.
