Hello RHUG Community,
I am currently working on a project to develop a Master Road Network using Esri Roads and Highways. The goal is to use this network as the master road network for a statewide travel demand model in TransCAD.
I have several questions and would greatly appreciate guidance or insights from those who might have experience with similar workflows:
1. Building the Master Road Network:
- What are the best practices for configuring the LRS (Linear Referencing System) schema to ensure it can handle a wide variety of attributes (e.g., AADT, lane configurations, speed limits, etc.)?
- How should I manage data integration when the source data comes from different databases?
- In my roadway data for divided roads like freeways, both directions are represented using a single polyline feature. Is it necessary (or recommended) to have two separate polylines/centerlines to represent each direction? If so, how should this be implemented in Esri Roads and Highways?
2. Integration with TransCAD:
- Is it feasible to export or transform the road network built in Esri Roads and Highways into a format compatible with TransCAD for travel demand modeling?
- Are there any known workflows, tools, or scripts that simplify this integration process?
Could you please tell me if you are aware of any DOTs, consultants, or agencies that have successfully used Esri Roads and Highways to build a road network and later integrated it into TransCAD for travel demand modeling? The project is in its early stages, and any advice, resources, or examples of related efforts would be immensely helpful.
Thank you in advance for your time and expertise!
