Abstract:

Activity-based (AB) microsimulation travel models are becoming the preferred modeling system for many agencies’ diverse transportation planning and policy questions. However, many of the AB models developed to date have been singular development efforts and often suffer from typical prototype problems such as correctness, stability, and comprehensiveness. As more agencies adopt AB models, and as AB models move from research into practice, their implementation and maintenance requires improvement. The purpose of this presentation is to describe the authors' experience integrating open source AB travel modeling systems for multiple agencies in the United States under one continuous integration (CI) system built upon state-of-the-art software development technologies and practices. CI is broadly defined as a collaboration practice where team members use a shared content management repository for tracking issues, software source code management, and testing. Each software revision is verified by an automated build and test system to detect problems early, in order to ultimately improve overall quality. Developing and maintaining advanced travel modeling tools in this online open source and collaborative workflow provides everyone in the team (developers, users, etc.) with a more robust, complete, and collaborative experience. Based on a search of the Transportation Research Record series, and on their industry knowledge, the authors believe this to be the first time such a system has been set up. The authors' presentation describes the entire system in detail, includes a discussion of the benefits and trade-offs to consider when designing such a system, and the implications for the research and practice of travel modeling.
