A-GaME’s Webinar Series: Ready When You Are & Geophysics Users Group Meetings

The FHWA put together its “A-GaME Summer Super Sessions Series” in 2022, specifically focusing on improving geotechnical site characterization practices for construction decisions and constructability. These sessions have been uploaded to Youtube and the links can be found below.

June 22, 2022 – Session 1: Step into the Contractor’s Boots. Hear directly from four contractors on the “asks,” risks and decisions they face when preparing bids and making decisions based on subsurface conditions that might or might not be well investigated, characterized or communicated. 

July 20, 2022 – Session 2: Manage Risk: Reduce Geotechnical Uncertainties Before Construction. Dive into the types of problems we experience during construction as a result of geotechnical uncertainties, and explore A-GaME technologies and other effective solutions to minimize those geotechnical uncertainties through case histories, applications of appropriate site characterization techniques and discussion. 

­­­­­­August 17, 2022 – Session 3: Bridge the Gap: Communicating Subsurface Conditions for Construction. Geotechnical subsurface investigations are not just about design parameters. Geotechnical site characterization must also inform constructability decisions and provide contractors with the information needed to get the job done efficiently and effectively. Explore ways to improve our investigation processes, to effectively communicate site conditions to all stakeholders, and to establish a collective understanding of anticipated conditions and contingencies for bidding and construction decisions. 


In recent years, the FHWA A-GaME webinar series has featured topics that highlight proven, effective exploration method and practices for enhanced, effective site characterization that reduce project risks, improve quality and accelerate project delivery.  Experts from the FHWA, state DOTs, industry and academia have covered everything from the nuts and bolts of A-GaME methods to visualization and design. 

If you missed the webinars live or want to review content, the archived webinars are now hosted on Deep Foundations Institute’s YouTube channel and available to watch on demand.

Trenton MOVES and the SmartDrivingCARS Summit

On February 11, 2022, New Jersey Department of Transportation (NJDOT) awarded a $5,000,000 Local Transportation Project Fund Grant to the City of Trenton to support the Trenton Mobility and Opportunity: Vehicles Equity System (MOVES) project. The core vision, goals and features of the project - an autonomous vehicle transportation system capable of serving 90,000 Trenton residents and commuting workers -- were outlined in a Request for Expressions of Interest (RFEI) issued in December 2021.

The system is expected to comprise 100 autonomous, electric shuttle vehicles and 50 kiosks and will operate solely as an on-demand system, with no fixed routes or schedules. The vehicles will be handicapped accessible and accommodate up to eight passengers.

Kiosks will be located at popular locations and high-density residential/commercial areas within a five-minute walk by over 90 percent of Trenton residents. Riders will be able to hail the vehicles through mobile devices or through an interface at each kiosk for those lacking access to a mobile device.

Through its partnership with Princeton University and the Corporation for Automated Road Transportation Safety (CARTS), NJDOT supported an extensive public outreach process to support the development of the RFEI. This outreach revealed several notable current conditions: 70 percent of Trenton households have one or no personal vehicle; due to land use decisions of prior decades and the lack of frequent bus service, seniors have to take circuitous bus rides, schedule an access-a-ride in advance, or walk significant distances to access destinations for everyday needs; and high school students living within two miles of the high school were without access to a bus because of a national bus driver shortage. The new system is intended to alleviate these and other limitations of the current transportation structure. The public engagement informed the RFEI and generated five goals for the program.

Goals of the Program

Safety

Autonomous vehicles can provide improved safety as they are not subject to human fallibilities, such as driving distracted or speeding. Some acclimation will be needed to ride in a vehicle with no driver. For the first two years of the project, vetted safety hosts will be on the vehicles to assist riders in understanding and navigating the system. The project will initially be limited to its operational design domain while on public roads.

NJ State Transportation Innovation Council Discusses Trenton MOVES at their 1st Quarterly Meeting of 2022

Equity

A significant majority of Trentonians live in Areas of Persistent Poverty, own one or no cars, and spend a high proportion of their income on transportation within the City. The program must serve the transportation needs of all Trenton residents, particularly those with limited transportation access due to economic or physical hardships. The service will aim to be inclusive both in terms of communities served and user experiences.

Affordability

The program will aim to be both low cost to the rider and the taxpayer. As NJDOT wants it to be both equitably and fiscally viable long into the future, its costs should be attainable and fares should be affordable. The rider should pay fares comparable to transit service, and far less than would be paid for ride-hailing and taxi services. Trenton MOVES will also create a public-private partnership to assist with the development of the on-demand mobility system and anticipate reduced costs through scaling and innovative funding mechanisms.

Sustainability

As New Jersey will be phasing out the sale of gasoline powered vehicles by 2035 to help reduce emissions, all of the initial 100 AVs in the Trenton MOVES project will be 100 percent electric. Additionally, the on-demand function stands to reduce average vehicle occupancy, vehicle miles traveled, and greenhouse gas emissions for local trips within Trenton.

Efficiency

To maximize the convenience of the on-demand mobility service, Trenton MOVES seeks to minimize wait times, ride times, have low circuity during shared rides, and reduce VMTs, particularly when the vehicles are empty. This goal will be achieved through active fleet management, dynamic repositioning, optimal routing, data analytics, etc.

How it will work

Trenton MOVES, Planned Operational Design Domain. CARTS

NJDOT anticipates a four-phase process to enable the autonomous vehicles within Trenton, and eventually to expand statewide and potentially beyond. Availability of service in Trenton is anticipated for early 2024.

Phase One will consist of the verification of the autonomous vehicle concept. The company selected to create this on-demand mobility service will first operate the autonomous vehicles on and around NJDOT’s Ewing campus to verify functionality in low stress environments.

Phase Two will be a proof of concept. Once the automated vehicles are shown to be effective, 100 vehicles will be placed on the public roads within a limited Operational Design Domain (ODD). This ODD will consist of major public centers in Trenton such as the Capitol Complex, schools, public housing, grocery stores, the Trenton Transportation Center, etc. A kiosk will be placed at each of these points to allow people to “call” to the vehicles.

Phase Three will be proof of societal value. In the third phase, the ODD will expand to all of Trenton to the point where 95 percent of the population is within a 5-minute walk of any kiosk. This expansion will demonstrate effectiveness of service, and scalability in an urban setting.

Phase Four is proof of network-scale economics. Once proven effective in Trenton, the program and the service could be launched throughout Mercer County, and in densely populated places in New Jersey such as Atlantic City, Camden, Newark, and New Brunswick. If those cities continue to prove effective in terms of service scalability, the autonomous vehicles can then be launched in more cities nationwide.

Upcoming Event - Princeton SmartDrivingCars Summit

From June 2nd to June 4th, CARTS and Princeton University have organized a gathering of leaders from within the industry, academia, public sector, and local communities to discuss the progress being made on the autonomous vehicle transportation. This year there will be an extensive discussion on Trenton MOVES as the program moves forward. To learn more, click here.

UHPC Bridge Preservation and Repair – NJ Efforts Highlighted

FHWA promotes UHPC for Bridge Preservation & Repair through its Every Day Counts (EDC-6) innovations. The FHWA's EDC Newsletter of April 28, 2022 featured Rutgers University's state-of-the-art Bridge Evaluation and Accelerated Structural Testing (BEAST) center.  FHWA has sponsored the use of the BEAST to evaluate emerging bridge preservation technologies including UHPC.  Below is a reprint of the newsletter article that recognizes these efforts as its Innovation of the Month for UHPC Bridge Preservation and Repair.

Wouldn’t it be great to quickly test the performance of a UHPC bridge deck overlay? It can be challenging to test and evaluate the long-term performance of new bridge preservation innovations because it would normally take years of monitoring the in-service behavior of such a technology on actual bridge structures to make an adequate assessment. Alternatively, Rutgers University’s state-of-the-art Bridge Evaluation and Accelerated Structural Testing (BEAST®) center provides a new opportunity to evaluate emerging preservation technologies. Built in 2015, the BEAST facility aims to develop high-quality data of bridge deterioration and to expand our knowledge of bridge performance through full-scale accelerated testing. The facility is capable of enclosing a 50-foot long bridge within an environmental chamber and subjecting the bridge to realistic rolling wheel loads, freeze-thaw cycles, and even the application of deicing chemicals. As a result, this facility can impose 10 to 20 years of ageing in less than 12 months.

FHWA is sponsoring the first project to utilize the BEAST® facility, and seeks to establish the long-term performance of bare reinforced concrete bridge decks and overlay systems among other variables. A two lane, 50 foot simply-supported bridge built with steel girders was constructed and began accelerated testing in 2019. To date, it’s been subjected to over 2-million passes of rolling load, 85 freeze-thaw cycles, and over 3000 gallons of salt brine. As a result, deck deterioration has reached a point where, in practice, an overlay would commonly be installed for rehabilitation and preservation purposes.

UHPC is one of the overlay systems that will be installed on this bridge specimen for evaluation. The UHPC overlay will be installed using materials and construction practices that are commonly deployed in the field. Once installed, accelerated testing will resume for at least 12 months, or until significant deterioration is again observed. Data will be collected, which will help establish quantitative measure of the overlays’ ability to perform long-term and under realistic conditions. Data already shows that UHPC is long-lasting and resilient, but at the end of this research, researchers will be able to say with greater confidence how long UHPC overlays may last in service.
