Good day everyone!
My research is to evaluate the performance of large multi-lane roundabouts considering weaving. I must introduce a method/model to estimate roundabout capacity, considering the crossing of entry and circulating vehicles.
Current progress: I just got the model modified and validated using local traffic data: lane-based entry flow, critical gap and follow-up headway. I decided to try the model with data from other countries' multi-lane roundabouts, to enhance the model's applicability (to show that the model predicts accurate results locally and in other countries - where roundabout geometry and drivers' behaviour could be drastically different).
I am looking for the following results:
1. circulating and entry flow under saturated conditions where queue occurs - I plan to plot a capacity plot (circulating flow vs entry capacity). Thus a duration of 60 minutes is just great (1 "dot" - 1 minute)
2. lane-based critical gap and follow-up headway
Yes, I don't get data for free. I am ready to share my local data as an exchange if you need it. Also, if the data provided to me are managed to include in any publication, I will inform the owner(s) of the authorship.
Thank you for your time.

It's great to hear about your research on evaluating the performance of multi-lane roundabouts considering weaving. To estimate roundabout capacity and analyze circulating and entry flow under saturated conditions, you can use various methodologies and models. Here are a few suggestions:
Regarding data from other countries' roundabouts, it would indeed be valuable to enhance the applicability of your model. Sharing your local data with researchers in exchange for their data can be a good approach to broaden the dataset and validate the model's performance across different contexts. Collaborating with researchers in different countries can also help in publishing comprehensive studies that encompass diverse scenarios.
It's important to ensure that proper acknowledgments and authorship are given when using shared data in publications. Clear communication and collaboration with data providers will help establish mutual understanding and ensure appropriate recognition of contributions.
Remember to adhere to ethical considerations and data protection protocols while sharing and using data from different sources. Compliance with privacy regulations and obtaining necessary permissions is essential.
Good luck with your research, and I hope it leads to valuable insights for improving roundabout design and performance!
