Webinar: Evaluating Sidewalk Infrastructure & Prioritizing Investment

Webinar Title

EVALUATING SIDEWALK INFRASTRUCTURE & PRIORITIZING INVESTMENT

Speaker(s)

Wes Marshall with Nick Coppola, University of Colorado Denver

Webinar Abstract

This project leverages advances in technology and increasing access to high-resolution remote sensing and spatial data to develop methods for inventorying sidewalk characteristics and static obstructions across an entire major city. In part 1 of this effort, we analyze city-scale sidewalk availability, width, and land coverage calculated from spatial data from aerial imagery (planimetrics). We then determine how much of a difference accounting for static obstructions makes when measuring the clear width of sidewalks in one city. Part 2 then combines planimetric sidewalk data with vehicle and pedestrian trip big data to develop a methodology to prioritize city areas in need of pedestrian infrastructure attention.

The results show an overall deficiency of sidewalks and indicate that deriving sidewalk availability, average width, and minimum clear width are feasible at the city scale. Moreover, the results suggest a significant decrease in the average clear width of sidewalks when accounting for static obstructions. Not accounting for static obstructions could lead to a gross overestimation of seemingly adequate sidewalks and an unrealistic assessment of sidewalk infrastructure and pedestrian accessibility. We then present a feasible and efficient method to prioritize pedestrian infrastructure in a city.

Primarily due to a lack of data, academic literature has scant research on sidewalks. In this project, we leveraged advances in remote sensing to bridge the data and research gap on pedestrian infrastructure in cities. These results will help cities that are lacking information rectify an unprecedented backlog of deteriorating pedestrian infrastructure.

Webinar: Advanced Non-Destructive Evaluation (NDE) Methods for Structural Concrete Assessment

Speaker: Larry Olson, PE
President and Chief Engineer
Olson Engineering, Inc.

About the Topic: NDE is being increasingly used to assess conditions of aging structures and infrastructure such as bridges, buildings and dams as well as forensic evaluation of such concrete problems as honeycomb, void and cracking in new structures.  Specific NDE methods to be discussed for these applications include ultrasonic pulse velocity, tomography, radar scanning, impact echo scanning,  and surface waves.  Also to be discussed is data fusion with photogrammetry to overlay NDE results on surface images.  Specific learning objectives include understanding NDE methods for condition assessment of corrosion induced delamination of bridge and parking decks, how to map out rebar with 3-D scanning and analyses with radar, and imaging of internal void/honeycomb in concrete with velocity tomography.

About the Speaker: Larry D. Olson, P.E., is internationally known for his expertise in nondestructive evaluation (NDE) of civil infrastructure including dams, bridges, buildings, foundations, pavements, tunnels, etc. He has 40 years of consulting experience in structural condition assessment and monitoring, materials, pavement, geotechnical, geophysical, and vibration engineering. He holds BS Civil and MS (Geotechnical) Engineering degrees from the University of Texas at Austin which honored him as a distinguished alumnus in 2006. He is a member of ACI Committees 228 Nondestructive Testing, 342 Bridge Evaluation and 309 Consolidation.

Waheed Uddin Faculty/Staff Diversity Award


Waheed Uddin Faculty/Staff Diversity Travel Grants 

 

In memory of Mississippi TriDurLE Site Director Waheed Uddin who passed away from COVID in 2020, TriDurLE will provide funding up to $1500 per award each year to four TriDurLE consortium university faculty or staff (postdoctoral researcher, engineer, coordinator, etc) who have participated in presentations/activities to enhance diversity. Grants are awarded post-travel (or virtual presentation) and receipts are required for reimbursement. Applicants will be required to explain how this travel helps the recruitment or retention of diverse students or professionals to the transportation infrastructure field and provide the number of people in attendance at the event.

Applications are open

  • These funding opportunities are available for faculty or staff from TriDurLE consortium universities only
  • All reimbursements will be allocated by TriDurLE and all faculty or staff who apply are not guaranteed funding
  • These grants are for reimbursement for registration and travel associated with academic or professional work related to promoting diversity, recruitment, and retention of students.
  • These are post-travel grants processed as reimbursements after you return from your trip (or virtual activity).

TRAVEL/CONFERENCE TYPES

  • Conference presentations
  • Workshops
  • Professional/Career development

ELIGIBILITY

  • All TriDurLE consortium university faculty or staff are eligible to apply for a TriDurLE travel grant.
  • Each faculty or staff can submit more than one application per travel period or academic year until the applicant reaches the maximum funding cap per travel period or academic year.
  • Faculty or staff are permitted to apply for more than one grant in the same cycle if they attended two events (conferences, workshops, etc.). They may be awarded partially based on available funding per travel period.

ELIGIBLE EXPENSES

Applicants must submit all original receipts (registration costs, travel receipts, etc.) and relevant information regarding travel; however for 2020-21 exceptions are allowed for this rule in the application process.

  • Registration fees
  • Transportation including airfare, shuttle costs, ground transportation, rental car, or personal cars per mileage
  • Airport parking
  • Lodging

INELIGIBLE EXPENSES

  • Any expenses for travel companions will not be reimbursed by TriDurLE
  • Meal costs will not be reimbursed

APPLICATION CRITERIA

Application is considered complete if the submitted application form includes the following fields

  • Attachment of travel receipts (exceptions are allowed for this for 2020-21 in the application process)
  • Strength of the event’s and/or presentation’s focus on diversity, recruitment, and retention

TIPS FOR APPLYING

  • When traveling, keep all original receipts and relevant information regarding your travel for reimbursement (This rule is applicable for 2021-22. If receipts are not available for 2020-21, exceptions are allowed)

Invited Speaker Webinar Series with M. Saiid Saiidi, PhD, PE., University of Reno Nevada

10:00 a.m. Pacific Time

 

Topic: “Seismic Performance of ABC (accelerated bridge construction) Bridge Systems”

Deployment of accelerated bridge construction (ABC) in high seismic zones has faced resistance due to uncertainties on seismic performance of connections between prefabricated bridge elements.  Research on development and evaluation of earthquake-resistant connections appropriate for ABC began to a limited extent over 15 years ago and intensified over the past decade.  By necessity, studies were mostly focused on component connections (known as ABC connections) such as column-footing, column cap beam, and superstructure cap beam linkage.  While the results of these studies identified appropriate details and led to preliminary design guidelines, questions still remained on the holistic seismic performance of bridges incorporating ABC connections.  Several bridge system studies in recent years have provided answers and have led to increased confidence in ABC in high seismic zones.  The presentation discusses a number of the more promising connections and how they were integrated into three, large-scale two-span bridges tested on shake tables of the University of Nevada, Reno.  The results also shed light on the relative performance of different types of ABC connections for concrete girder and steel girder bridges with a variety of column connections.
