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