This specialized visual tool brings important documents and data together, incorporates customized information, and evolves it to meet client needs in modern and easy to understand metrics.


The Future Of Transportation Funding, Steve E. Morello Mar 2022

The Future Of Transportation Funding, Steve E. Morello

Purdue Road School

Among the many collaterals impacts of vehicle electrification is a reduction in funding for government agencies who rely heavily on fuel taxation—over 75B annually—for transportation needs. States and the federal government are actively exploring user-based funding alternatives to pay for the next generation of roads that will be used by the next generation of vehicles.

Missed That! Roadway Drainage Lessons Learned, Michael Mills Mar 2022

Missed That! Roadway Drainage Lessons Learned, Michael Mills

Purdue Road School

Intersection improvements and downtown beautification projects are common essential improvements that benefit motorists and residents of urban communities. When scoping, it is easy to disregard drainage in order to minimize cost and reduce staffing needs. However, sometimes big problems can happen when roadway drainage is not assessed. Come take a deep dive into a few examples of drainage oversights and how they were remedied.


To Lead Or Not To Lead?, Matt Sagstetter Mar 2022

To Lead Or Not To Lead?, Matt Sagstetter

Purdue Road School

Why doesn’t the flashing arrow work anymore? The green arrow doesn’t turn on, is there something wrong? These questions and more will be answered in a discussion about the operation, implementation, and education of flashing yellow arrows (FYAs) at signalized intersections. Case studies of specific intersections in Indiana will be used to show the crash history and risk analysis used to make decisions related to overall signal operation and driver safety.


Big Data Applications: Public Involvement Tools For Public Involvement, Amy L. Livingston, Houssam Ghandour Mar 2022

Big Data Applications: Public Involvement Tools For Public Involvement, Amy L. Livingston, Houssam Ghandour

Purdue Road School

Using big data to better understand origin-destination and regional travel patterns is critical to project development. Tools such as passive geographically based data lead to improved definitions for traffic analysis zones (TAZs), which, in turn, help inform public involvement plans for a more targeted approach and improved equity. This presentation will highlight future planning applications in Indiana and other case examples where we have used big data to aid the plan development of public and stakeholder engagement.


Accommodating Rapid Development In Design Level Forecast A Regionally Minded Methodology, Randy Kill Mar 2022

Accommodating Rapid Development In Design Level Forecast A Regionally Minded Methodology, Randy Kill

Purdue Road School

Rapid large-scale development presents challenges for traffic engineers to accurately forecast design-year traffic volumes. Prevailing forecasting methods, such as the ITE Trip Generation Manual, tend to exaggerate local traffic impacts on large developments and do not account for regional influences. This presentation outlines the methodologies for developing the design level forecast of two large freeway projects amid largescale private developments. This approach provides significant improvements over traditional trip generation methods and model-based forecasts.

Rehabilitation Of I-70 Composite Pavement Using Peel And Stick Strip Membrane & Geosynthetic Paving Fabric Interlayer, Kumar P. Dave, Pankaj G. Patel Mar 2022

Rehabilitation Of I-70 Composite Pavement Using Peel And Stick Strip Membrane & Geosynthetic Paving Fabric Interlayer, Kumar P. Dave, Pankaj G. Patel

Purdue Road School

I-70 composite (asphalt over concrete) pavement is being rehabilitated using peel and stick membrane and geosynthetic paving fabric. The innovative rehabilitation technique is the first time peel and stick membrane is being used with geosynthetic paving fabric on the existing concrete pavement of the interstate. This combination retards reflective cracking and acts as a moisture barrier, which extends the service life of the treatment.

Forecasting Electric Vehicle Adoption At A Local Level, Jonathon Sinton Mar 2022

Forecasting Electric Vehicle Adoption At A Local Level, Jonathon Sinton

Purdue Road School

The Biden administration has recently stated as a major policy goal that 50% of all new vehicle sales will be electric by the year 2030. However, current electric vehicle (EV) uptake sits at about 2.4% of current vehicle sales. Additionally, the administration’s goal is more ambitious than current forecasts predict will occur. Given the gap between the administration’s goals and the current EV trends, it is necessary to better forecast how current trends will progress and better understand what factors influence these trends. The purpose of this research is two-fold: to create better forecasts of EV adoption ...

Inventing The Baby Saver: An Activity Systems Analysis Of Applied Engineering At The High School Level, Jessica Gale Mar 2022

Inventing The Baby Saver: An Activity Systems Analysis Of Applied Engineering At The High School Level, Jessica Gale

Journal of Pre-College Engineering Education Research (J-PEER)

Extant research and engineering education frameworks call for students to engage in personally meaningful engineering projects; however, there are few case studies documenting the work of young engineers working to design solutions to real-world problems that matter to them. This qualitative case study describes the work of a purposively selected group of high school engineering students (the InvenTeam) (n = 15) as they devote a school year to a particularly ambitious invention project: designing and prototyping a device to mitigate deaths occurring when children are left unattended in hot cars. Utilizing cultural historical activity theory as a theoretical and analytical lens ...


Observing Empathy In Informal Engineering Activities With Girls Ages 7–14, Susan M. Letourneau, Dorothy T. Bennett, Changchia Liu, Yessenia Argudo, Kylie Peppler, Anna Keune, Maggie Dahn, Katherine Mcmillan Culp Feb 2022

Observing Empathy In Informal Engineering Activities With Girls Ages 7–14, Susan M. Letourneau, Dorothy T. Bennett, Changchia Liu, Yessenia Argudo, Kylie Peppler, Anna Keune, Maggie Dahn, Katherine Mcmillan Culp

Journal of Pre-College Engineering Education Research (J-PEER)

Empathy is a critical part of the engineering design process. It allows engineers to more deeply understand their clients’ perspectives and design solutions that meet the needs of diverse stakeholders. Studies also show that reframing engineering education to prioritize empathy for others can counteract stereotypes of engineering as impersonal and invite a wider range of identities into the field. This approach can help to address persistent gender disparities in engineering, which reflect a need for engineering education to increase its efforts to include girls’ perspectives. Informal learning environments have developed strategies for framing engineering problems in human-centered ways, but more ...


Blast Analysis Of Steel-Plate Composite Slabs: Sdof And Fem Analyses, Joshua R. Harmon, Amit H. Varma Feb 2022

Blast Analysis Of Steel-Plate Composite Slabs: Sdof And Fem Analyses, Joshua R. Harmon, Amit H. Varma

Bowen Laboratory Research Reports

Steel-plate composite (SC) members have emerged as competitive construction methods for tall buildings and nuclear power plants. Detailed design guidance has been created for these functions and design of these members is now covered in AISC 341-16 and ASIC N690-18. However, SC members are emerging for use in protective structures to withstand blast and impact loads. Although experimental tests of SC members for blast resistant design have been conducted, design of SC members for blast loads has not been addressed in existing design references for blast loadings (UFC 3-340-02). This report details a general design philosophy for blast loaded SC ...
