Near-Road Emissions and Dispersion Modeling
Evaluate and minimize near-road pollution, which disproportionately affects disadvantaged and environmental justice communities. Our scientists develop high-quality emissions inventories and air quality assessments to provide fact-based solutions for near-road projects.
Emissions and Air Quality Analysis
Develop emissions inventories and near-road pollutant concentration estimates that reflect background concentrations and roadway impacts.
Mitigation Research
Identify cost-effective methods to mitigate near-road air pollution impacts, protect children and other sensitive groups, and enable project delivery and completion.
Near-Road Air Quality Measurements
Measure real-world air quality adjacent to major roads. We design and implement short- to long-term measurement campaigns customized to answer your analysis questions.
Model-to-Monitor Comparisons
Collect and assess traffic, meteorological, and pollution data to understand the factors contributing to real-world pollution conditions and evaluate how well modeling tools simulate actual conditions.
Near-Road Impacts and Mitigation
Understand near-road pollutant concentrations; implement and track the effectiveness of mitigation approaches to reduce pollutant exposure; and communicate effective health protection measures to decision makers and the public.
Regulatory and Data Analysis Support
Leverage our technical expertise to solve your compliance and data analysis issues. STI has successfully worked with both industrial clients and regulatory agencies—our proven track record engenders a high level of trust in our analyses and allows us to help clients better understand and navigate the regulatory environment.
Conformity Hot Spot Analysis
Understand the location and magnitude of emissions and air quality impacts to meet conformity regulations.
Litigation Support
Leverage STI's scientific knowledge and wide-ranging litigation support experience with our technical analysis and expert testimony. We have worked with attorneys from government agencies and private law firms for over two decades.
Health and Exposure Assessment Studies
Meet your research needs with in-depth exposure studies; map and visualize traffic-related emissions and air quality to assess public exposure and health impacts. Our study design services provide clients with plans and technical rationale for the collection of data most important for achieving study objectives.
Exposure Model Development
Identify how vehicle-related emissions are transformed in the atmosphere, resulting in air pollution exposure.
Emissions Modeling
Quantify emissions from on-road vehicles, off-road equipment, and other pollution sources using the latest federal- and state-approved modeling tools.
Emissions Inventory Evaluation and Improvement
Improve your emissions inventories. STI scientists have developed and refined methods to evaluate and improve current and forecast emissions.
Activity Data Collection (including Public Surveys)
Have confidence in your data results; we work with clients to collect a wide range of emissions-related activity data from sources such as cars, trucks, buses, and agricultural operations.
Software and Tool Development
Create a customized software tool solution to simplify project and regional-scale emissions and air quality analysis. STI develops, manages, and enhances software tools, decision support systems, and applications that are customized to meet our clients' scientific goals.
On-Road Emissions Model
Better estimate the on-road pollutant emissions from your transportation projects with software tools that quantify greenhouse gases, criteria pollutants, and mobile air source toxics emissions.
Scenario Analysis Tools
Develop specialized tools to support your scenario analyses for on- and off-road vehicle use.
User-Friendly Interfaces
Upgrade your air quality and emissions modeling with easy-to-use interfaces designed by our modeling and air quality experts.
