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.

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 at the zip …

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 …

Epics Lakota: Promoting Food Sovereignty On Pine Ridge Indian Reservation, Samantha Bijonowski, Kathleen Johnson, Jonathan Damon Oct 2021

Epics Lakota: Promoting Food Sovereignty On Pine Ridge Indian Reservation, Samantha Bijonowski, Kathleen Johnson, Jonathan Damon

Purdue Journal of Service-Learning and International Engagement

EPICS Team Lakota was started as a way for students to help promote food sovereignty and combat loss of cultural knowledge as felt by the residents of Pine Ridge Reservation, which is located in one of the poorest counties in the United States and is a food desert. In partnership with EPICS students at Oglala Lakota College (OLC) and South Dakota School of Mines (SDSM), students at Purdue came up with the idea of putting up a greenhouse on the Rapid City Campus of OLC. This greenhouse was meant not as a direct solution to food scarcity, but as a …

Adapting Global Service-Learning Project And Community Partnership Outcomes Using A “Tele-Engineering” Approach In Response To The Covid-19 Pandemic, Christiane Ley, Danielle Angert, Tessa Hudelson, Jordan Harris

Purdue Journal of Service-Learning and International Engagement

The Water Supply in Developing Countries (WSDC) service-learning course at Purdue University has fostered a strong partnership with the La Vega region in the Dominican Republic since 2012. During this time, an interdisciplinary group of engineering and science students has helped design drinking water treatment systems and the group has developed water, sanitation, and health (WASH) education materials. These WASH education and water safety approaches often have been conducted in person in the past. However, with the state of the COVID-19 pandemic and the inability to travel in the fall and spring semesters of the 2020–2021 academic year, the students …

Cluster Forecasting Of Corruption Using Nonlinear Autoregressive Models With Exogenous Variables (Narx)—An Artificial Neural Network Analysis, Seyedali Ghahari, Cesar Queiroz, Samuel Labi, Sue Mcneil Oct 2021

Cluster Forecasting Of Corruption Using Nonlinear Autoregressive Models With Exogenous Variables (Narx)—An Artificial Neural Network Analysis, Seyedali Ghahari, Cesar Queiroz, Samuel Labi, Sue Mcneil

Purdue University Libraries Open Access Publishing Fund

Any effort to combat corruption can benefit from an examination of past and projected worldwide trends. In this paper, we forecast the level of corruption in countries by integrating artificial neural network modeling and time series analysis. The data were obtained from 113 countries from 2007 to 2017. The study is carried out at two levels: (a) the global level, where all countries are considered as a monolithic group; and (b) the cluster level, where countries are placed into groups based on their development-related attributes. For each cluster, we use the findings from our previous study on the cluster analysis …

Detection And Tracking Of Pedestrians Using Doppler Lidar, Xiaoyi Peng, Jie Shan Jul 2021

Detection And Tracking Of Pedestrians Using Doppler Lidar, Xiaoyi Peng, Jie Shan

Lyles School of Civil Engineering Faculty Publications

Pedestrian detection and tracking is necessary for autonomous vehicles and traffic manage- ment. This paper presents a novel solution to pedestrian detection and tracking for urban scenarios based on Doppler LiDAR that records both the position and velocity of the targets. The workflow consists of two stages. In the detection stage, the input point cloud is first segmented to form clus- ters, frame by frame. A subsequent multiple pedestrian separation process is introduced to further segment pedestrians close to each other. While a simple speed classifier is capable of extracting most of the moving pedestrians, a supervised machine learning-based classifier …
