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
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 …

A Statistical Principal Component Regression-Based Approach To Modeling The Degradative Effects Of Local Climate And Traffic On Airfield Pavement Performance, Evan M. Fortney, Steven J. Schuldt, Sarah L. Brown, James P. Allen, Justin D. Delorit
Faculty Publications
Airfield pavement systems support the global economy, passenger travel, and national defense. Accurate pavement degradation predictions are critical inputs for maintenance and repair decisions, and when skillful, they may reduce the need for time-intensive, costly physical inspections that disrupt airfield operations. Existing airport pavement management systems (APMS) compute expected degradation as a function of pavement type and age, but they do not account for local climate and traffic conditions and they are not built to adapt to future changes in either mode of variability. This paper implements a bias-reduced statistical model that reveals the effects of local conditions using observed …

Evaluation Of Cost-Effective Alternative Designs For Rural Expressway Intersections, Jonathan Howard
Master's Theses
Despite numerous studies demonstrating the effectiveness of Restricted Crossing U-Turn (RCUT) intersection design, its implementation remains uneven and close to zero in some large states such as California. This research provides a comprehensive framework to estimate the operational and safety performance of future RCUT designs in California. The framework is demonstrated for five intersections located on high-speed rural expressways in California using VISSIM microsimulation models to measure operational performance for each intersection including the base condition with the existing Two-Way Stop-Controlled (TWSC) intersection and two RCUT designs. To evaluate future safety performance, the microsimulation models were further utilized to compile …
