Demo
ASAP is a software tool developed by researchers at Portland State University that tries to simplify and standardize GPS and related spatial activity data processing. In a few steps, ASAP turns raw data about locations and activity levels into spatial information suitable for transportation, health, and other analysis. The primary focus of the original developers was research on active travel (walking and biking for transportation), and ASAP is especially useful active travel analysis. This demo introduces the key concepts and components of ASAP.Basics
ASAP runs locally on most any Windows, Mac, or Linux desktop computer. You interact with ASAP via a web browser. This keeps the interface simple, but everything stays local--there is no need to upload your data to the web. In fact, you don't even need an internet connection. ASAP is designed to augment wearable GPS data and (optionally) accelerometer data with information about trips, travel modes (walk, bike, transit, auto), routes, and activities.Why ASAP?
ASAP has a number of unique features that we hope make it useful to others...- Free and open source
- Handles completely passive data (no participant diaries)
- Includes broad range of outputs, including mode detection and map matching to travel networks
- Designed to be extended by users with new capabilities
- Runs locally--no need to upload data
- Built to handle any size data collection (original use included nearly 10,000 days of spatial activity data)
- Does not require extensive GIS or database skills
- Encourages standardization and sharing of protocols for research replication
