Andrew Kwasniak, PhD, PE, PTOE, ACTAR

Dr. Andrew Kwasniak is a transportation safety engineer whose work combines roadway safety engineering, crash-data analysis, Highway Safety Manual methodologies, Safety Performance Functions (SPFs), network screening, and the development of practical transportation safety technology.

Development of SPF Tool

Andrew Kwasniak has been closely involved in the development and implementation of SPF Tool, a web-based transportation safety analysis platform designed to help transportation professionals apply Safety Performance Functions, Highway Safety Manual methodologies, and data-driven roadway safety analysis.

His work with SPF Tool reflects experience in both the engineering principles behind predictive safety analysis and the practical challenges transportation agencies face when working with crash data, roadway inventories, network screening, jurisdiction-specific Safety Performance Functions, and identification of locations with potential for safety improvement.

Safety Performance Functions and Highway Safety Manual Analysis

Dr. Kwasniak's transportation safety work includes the development, application, and evaluation of Safety Performance Functions, Highway Safety Manual predictive methods, crash modification factors, network screening techniques, crash-data analysis, and location-specific roadway safety evaluation.

His research and professional work has included the evaluation of jurisdiction-specific Safety Performance Functions and comparison of locally developed predictive safety methods with national models.

Transportation Safety Engineering

Dr. Kwasniak's broader engineering experience includes roadway and intersection safety, roadway geometric design, traffic control devices, work zones, pedestrian and bicycle facilities, accessibility, sight distance, crash analysis, driver perception, and human factors.

His professional work has included transportation engineering and safety assignments across more than 35 U.S. states, along with proactive and systemic roadway safety evaluations for transportation agencies and other clients.

Research and Publications

Andrew Kwasniak earned his PhD in Civil Engineering from Purdue University. He has authored and contributed to technical publications addressing transportation safety, Safety Performance Functions, roadway engineering, high-crash-site investigation, pedestrian safety, human factors, and transportation technology.

His research includes work involving Safety Performance Functions for urban signalized intersections, high-crash-site investigation, roadway safety programs, pedestrian and crosswalk behavior, and applications of emerging technology in transportation engineering.
