MONTHLY REPORT

1 | P a g e

In order to understand the vehicle classes and groupings, the MnDOT “Vehicle Classification Scheme” and the “Vehicle Classification 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 show at http://www.dot.state.mn.us/traffic/data/reports-monthly-wim.html For the month of August 2013, the system appeared to be operating normally. Volume was computed using all monthly data. The data in this report uses the data that was collected for the month (no extrapolations performed). VOLUME For WIM #39 on MN 43 at mile post 45.2 in Winona, there were 349,850 vehicles that passed the site for the month of August. The Average Daily Traffic (ADT) and Heavy Commercial Average Daily Traffic (HCADT) were respectively 11,285 and 678 in August 2013. 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 (northbound vs. southbound; NB vs. SB) and as a function of time (weekday). The average numbers of vehicles traveling NB and SB peaked on Fridays, while lowest volumes were reported on Sundays for both directions. 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 2:30 pm and 6:30 pm for NB passenger vehicles, while volume peaked between 6:30 am and 8:30 am for SB passenger vehicles. Data also showed that passenger vehicle traffic volume was roughly the same going NB and SB (50.1% of all passenger vehicles were traveling NB, while 49.9% of all passenger vehicles were traveling SB). For heavy commercial vehicles, volume going NB peaked between 8 am and 2 pm, while volume going SB peaked between 9 am and 3 pm. Heavy commercial vehicles were also reviewed for directional volume differences; heavy commercial vehicles tended to travel slightly more SB than NB. VEHICLE CLASSIFICATION The traffic volume consisted of 328,829 passenger vehicles (94.0%) and 21,021heavy commercial vehicles (6.0%). Table 1 summarizes traffic volumes by vehicle class, as well as providing traffic volume information for 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 data was 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 August 2013 was 349,850 and 21,021, respectively. The total number of overweight vehicles was 3,001, which

2 | P a g e

translates into 0.9% of total traffic (or 14.3% of heavy commercial vehicles). Figure 1 shows the average number of overweight vehicles traveling directionally (NV vs. SB) as a function of time (weekday). For both NB and SB overweight vehicles, traffic volume was highest over the weekdays (weekday traffic volume was roughly the same from Mondays through Fridays). Lowest traffic volumes for overweight vehicles were observed over the weekends for both directions. 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 a function of time (hour of day). Class 9 overweight vehicles had volume peaks between 9:30 am and 1:30 pm, while Class 10 overweight vehicles had volume peaks between 7:30 am and 2:30 pm. The overweight vehicles were also reviewed for any directional differences. Data shows that over 78% of the overweight vehicles were going SB. Figure 4 shows total volume of overweight vehicles as a function of time (hour of day), with volumes also calculated by direction. Figure 5 shows the number of vehicles during the last 12 months that crossed the WIM that weighed more than 88,000 pounds. The chart shows that the numbers of vehicles over 88,000 pounds has been growing since January 2013. This may reflect a seasonal trend in which one is less likely to see high volumes of 88,000+ pound vehicles over the late fall and winter seasons. Figure 6 shows the gross vehicle weight distribution for Class 9’s and 10’s traveling both directions (NB and SB). Figure 6 illustrates that there were more empty than full Class 9’s going both directions (NB and SB). Data also suggests that there were more full than empty Class 10’s going both directions. WIMs are a screening tool for weight enforcement. 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 considered overweight. These may still be permitted loads. For the most efficient use of personnel and equipment, these overweight vehicles should be weighed on static scales and reviewed for permits. During normal load limits, 6 vehicles traveling NB were over 88,000 pounds (4 were Class 9’s; none were Class 10’s). Of vehicles traveling SB during the normal load limits, 501 vehicles were over 88,000 pounds (276 were Class 9’s; 221 were Class 10’s). Table 2 summarizes the Top 10 Gross Vehicle Weight for Class 9 and Class 10 vehicles for August 2013. SPEED The speed limit on MN 43 at the WIM site is 50 mph. Less than 0.2 miles from the WIM, the speed limit goes up in the NB direction from 40 mph to 50 mph. In addition, less than 0.2 miles from the WIM, the speed limit decreases in the SB direction from 50 mph to 40 mph. Combining both lanes in August 2013, the following was recorded at WIM #39: 1) average speed of 49 mph, 2) median speed of 50 mph, and 3) an 85th percentile speed of 54 mph. Table 3 summarizes the vehicle data for the Top 20 speeders that crossed WIM #39 in August. The speed of the Top 20 ranged from 70 mph to 97 mph. Figure 7 shows the average speed of passenger vehicles and heavy commercial vehicles as a function of direction (NB vs. SB) and time (hour). Depending on the hour

3 | P a g e

of the day, there is just under a 1 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. For August 2013, the average speeds varied between 45 mph and 52 mph. Figure 9 shows the average speed as a function of direction (NB vs. SB). 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 August 2013, WIM #39 encountered 349,850 vehicles and recorded a total weight of 2,115,115 kips (1 kip = 1,000 pounds). Figure 10 summarizes the total 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 August 2013, a total of 14,671 equivalent single-axle loads (ESALs) passed over the pavement at WIM #39. Approximately 64.5% of the ESALs were in the SB lane, while 35.5% of the ESALs were in the NB lane. Figure 12 graphically depicts the total ESALs by vehicle class and direction. 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 70.8% of the ESALs while they are only 26.1% 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 August 2013, ESALs were largest in Lane 2 (SB lane). Therefore, the SB lane is the design lane, and the growth factor for this section of MN 43 in Winona County is 1.1%. For the SB lane, there were 1,222 Class 9 trucks and 502 Class 10 trucks over 80,000 pounds. These 1,724 vehicles generated 5,066 ESALs. If all of these trucks weighed just 80,000 pounds they would have generated 3,913 ESALs—1,153 ESALs lower. If you take August’s SB lane ESALs of 9,460 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 2,769,978. If you go through the same calculation but start with a monthly value of 8,307 (SB lane ESALs without all of the overweight Class 9 and 10 vehicles), you come up with 2,432,372 20-year BESALs. The difference between the 20-year BESALs, divided by 9,460 ESALs, is 35.69 months. This translates into the pavement reaching its 20-year design life close to 3 years earlier due to the overweight Class 9’s and 10’s. This is a quick, back-of-the-napkin calculation for 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 weight being shipped stays the same.

FREIGHT For WIM #39, it was calculated that 173,824 tons of freight crossed the sensors. More freight was shipped SB (110,552 tons) versus NB (63,273 tons). Table 6 summarizes 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 #39 was most recently calibrated on January 24, 2013. 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 weight of the Class 2’s, 3’s, and 9’s by lane. The current goal of the calibration is to have each individual axle stay within a range of ±9% of baseline calibration. Table 7 shows that the front axle weight was within the range of ±9% for all three classes (Classes 2, 3, and 9) and 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 and 16 show histograms of the monthly GVW of Class 9’s over the last 12 months for Lanes 1 and 2. Figure 17 depicts unloaded and loaded peaks as a function of lane (Lanes 1 - 2) and date. There are enough Class 9’s in Lanes 1 and 2 that a histogram can be generated on a semi-monthly basis. Overall, WIM #39 is working fine and is staying within calibration range. SUMMARY In August 2013, the average volume of NB and SB traffic peaked on Fridays and was lowest on Sundays. For both NB and SB overweight vehicles, highest volumes were reported during the weekdays (numbers were roughly the same across the days), with lowest volumes reported over the weekends. Over 78% of the overweight vehicles were going SB. Traffic volume for overweight vehicles peaked from 9:30 am to 3 pm. Of the Class 9’s, 17.5% of them were overweight, while 43.5% of Class 10’s were overweight. When observing the volume of vehicles weighing over 88,000 pounds over the last 12 months, July and August 2013 achieved the highest numbers. The speed of the traffic did not vary significantly based on vehicle class, lane, or hour of the day. The GVW was higher in the SB direction than NB direction (1,136,771 kips vs. 978,344 kips). A similar pattern emerged for ESAL and freight data. SB ESALs were higher than NB ESALs (9,460 ESALs vs. 5,211 ESALs), and freight tonnage was also greater going SB than NB (110,552 tons vs. 63,273 tons). Data calculations from August 2013 also suggest that overweight Class 9’s and 10’s are shortening the 20-year BESAL design life by close to 3 years. Please see Table 8 for a summary of some of the key data over the last 12 months.
