Title: Enhancing Truck Parking Information Management System (TPIMS) Objective: To create a comprehensive TPIMS that primarily utilizes anonymized ELD data for tracking truck parking events, supplemented by rest area Wi-Fi connectivity and advanced Wi-Fi scanning technologies for verification and enhanced accuracy. Primary Layer: ELD-Based Parking Event Tracking
  1. ELD Data Utilization: The system will prioritize the use of ELD data, which includes geolocation and engine status. The data will be anonymized and used to determine parking events as trucks come to rest, in line with FMCSA mandates.
  2. Anonymization and Data Integration: Anonymized ELD data will be processed and integrated into TPIMS, ensuring driver privacy while providing valuable insights into parking space usage patterns and availability.
  3. Regulatory Compliance: The project will maintain strict adherence to FMCSA regulations regarding the handling and usage of ELD data.
Secondary Layer: Wi-Fi Connectivity in Rest Areas
  1. Rest Area Network Utilization: The Wi-Fi systems in rest areas will serve as a secondary method for confirming parking events, where trucks connecting and disconnecting from the network will indicate arrival and departure times.
  2. Connectivity Feedback Loop: Wi-Fi network engagement will provide a feedback loop for ELD-reported parking events, enhancing the reliability of the system.
Tertiary Layer: Advanced Wi-Fi Scanning Technologies
  1. Perception Capabilities: Incorporating Wi-Fi scanning technologies to perceive and monitor the parking environment, providing a tertiary data source for confirming parking space occupancy.
  2. Research and Development: Collaborate with leading research institutions to refine Wi-Fi scanning methods and integrate them into TPIMS, leveraging research such as that from Carnegie Mellon University's Robotics Institute.
Integration and Collaboration:
  • Carnegie Mellon University: To provide expertise in Wi-Fi scanning and perception capabilities for the TPIMS.
  • Iowa Department of Transportation: To facilitate the implementation and management of the TPIMS and ensure compliance with transportation regulations.
  • ELD Providers and Trucking Industry Stakeholders: To collaborate on the anonymized data sharing necessary for the primary ELD-based component of the system.
Description
Iowa is the global epicenter for organic waste (i.e., manure, food, sewage sludge) volume and a world leader in tailored biomass (i.e., corn, soy, algae) production. These organics can be converted into desirable bio-based carbons, including bio-bitumen and polymers for asphalt, and biocrude for sustainable transportation fuels (e.g., biodiesel, aviation fuel). The thermal catalytic processes that convert these waste organics into valuable carbon also degrade “forever chemicals” (i.e., PFAS) and other contaminants of concern as a valuable side benefit. An Iowa-based company is currently converting soy to biobased asphalt products, but a massive leap in feedstock conversion must take place to truly impact the sustainability of asphalt and transportation fuels at scale. Another Iowa company is making stunning advances in growing easy-to-harvest algae in municipal and industrial settings, but the algae market is still developing. Therefore, this project seeks to leverage success in Iowa to extend the suite of abundant organic feedstocks deemed suitable to produce biobased asphalt products and sustainable transportation fuels.

The use of E5 products in bridge deck concrete has grown in recent years in the Midwest. Indiana DOT was one of the first states to adopt use of this product (https://www.in.gov/dot/div/contracts/conmemo/24-03.pdf). The primary benefit claimed by manufacturers is a durable concrete with reduced cracking and limited need for wet curing. The product also results in a significant reduction of cement. More information can be found here: https://www.e5nanosilica.com/e5products. Iowa has issues with early age bridge deck cracking and is actively looking for solutions.

Recent changes by US cement manufactures to reduce carbon emissions has brought changes to cement available. The commonly used Type I or II is no longer available and has been replaced by ASTM C595 Type IL, also known as Portland Limestone Cement. ASTM C595 Type IP and IS have been used in Iowa since 1995. Future products are likely to be Type IT cements, with a ternary blend of Portland cement, slag cement, calcined clay, and limestone or other materials. Some of these new cements may have 50% of the clinker replaced.
In the past couple years since the new PLC cements have been used, the concrete industry has reported issues with concrete strength gain, ultimate concrete strength, shrinkage cracking and scaling.
