After developing and testing the sensing system in the laboratory, verification tests will be conducted at a local parking lot and the university campus roads. Tests are also planned tests at Minnesota’s MnROAD facility to verify the validity of the detection using the controlled truck traffic. Work in Stage 2 will involve field evaluation and validation of the developed prototype system. The system will be installed in the field adjacent to several WIM locations. The application of the system will be demonstrated by analyzing field data to identify (a) the type and frequency of various super single tires (WBT) on a particular route, (b) lateral distribution of wheels in the wheel-path (i.e., wheel wander), and (c) axle load spectra for WBT vs. conventional dual tires. Stage 2 will also involve field data collection in Michigan and Minnesota to demonstrate the sensor system’s practicality and obtain feedback from state DOTs. At least 2-3 sites will be selected in these states, preferably adjacent to a WIM sensor, and the sensor system will be installed for data collection for at least 1-5 days in the outer lane. Data will be collected on the tire width, the exact number of tires per axle, and their position along the cable (position along the lane). The information will be used to classify tire types (i.e., WBT vs. dual); it will also precisely measure the wheel wander. The obtained data will be synthesized to show the usefulness of the developed sensor system by summarizing (a) differences in axle load spectra (ALS) -- single and tandem axles for dual tires and WBTs; (b) wheel wander distributions; and (c) vehicle classes compared from the existing WIM system and the sensor for each site. A life cycle cost analysis (LCCA) of the sensing system will be performed. The final report will provide all relevant data, methods, models, and conclusions, along with guidance on using the system to collect WBT data by state DOTs.]]> Mon, 11 Jul 2022 17:41:25 GMT https://rip.trb.org/View/1992631 Addressing the research needs for the sustainable application of TDA (Tire Derived Aggregate) in stormwater infiltration/treatment https://rip.trb.org/View/1917689 Wed, 16 Feb 2022 11:52:27 GMT https://rip.trb.org/View/1917689 Quantifying the Impact of Super Single (Wide Base) Tires on Pavement Damage in Michigan https://rip.trb.org/View/1860937 Mon, 21 Jun 2021 10:51:15 GMT https://rip.trb.org/View/1860937 The Effect of Rubber Fills on the Performance of Infrastructure, Phase 1 https://rip.trb.org/View/1694109 Fri, 20 Mar 2020 14:32:31 GMT https://rip.trb.org/View/1694109 The Impact of Wide-Base Tires on Pavement Damage: A National Study https://rip.trb.org/View/1362143 Wed, 22 Jul 2015 01:02:49 GMT https://rip.trb.org/View/1362143 Computational Synthesis of High-Performance Non-Pneumatic Tires https://rip.trb.org/View/1352481 Tue, 05 May 2015 01:00:39 GMT https://rip.trb.org/View/1352481 Environmental Impacts and Energy Efficiency of Rubberized Warm Mix Asphalt (R-WMA) for Sustainable Road Construction https://rip.trb.org/View/1236251 Thu, 03 Jan 2013 15:43:44 GMT https://rip.trb.org/View/1236251 Co-Simulation of Heavy Truck Tire Dynamics & ESC https://rip.trb.org/View/1232734 Thu, 03 Jan 2013 14:43:50 GMT https://rip.trb.org/View/1232734 Co-Simulation of Heavy Truck Tire Dynamics & ESC (Phase A) https://rip.trb.org/View/1232729 Thu, 03 Jan 2013 14:43:44 GMT https://rip.trb.org/View/1232729 PoroElastic Road SUrface: PERSUADE https://rip.trb.org/View/1229782 Thu, 03 Jan 2013 13:48:33 GMT https://rip.trb.org/View/1229782 Scrap Tire Research https://rip.trb.org/View/1228183 Thu, 03 Jan 2013 13:16:10 GMT https://rip.trb.org/View/1228183
