This folder contains the traffic data used in the study for calibrating Traffic Flow Models.
This is a post-process of data recorded from PeMS data.
We are releasing this data for reproducibility. The DOI of the preprint is here:
- Jeffrey Bottleneck: contains 12 days of traffic data. The station just downstream of the bottleneck (downstream flow) is 1209076
- 3lanes (A20) Bottleneck: contains 6 days of traffic data. The station just downstrem of the bottleneck is 401586
The data reconciliation so that upstream and downstream we have the same total count over time is here:
Both jeffrey_data.csv and 3lanes_data.csv follow the same structure:
| Column | Description |
|---|---|
| Year | Year of the observation |
| Month | Month of the observation |
| Day | Day of the observation |
| TimeStep | The index of the measurement step (typically 2-minute intervals) |
| UpstreamDemand | Measured flow entering the section from upstream (veh/time-step) |
| RampCounts | Measured flow entering the section from the on-ramp (veh/time-step) |
| DownstreamCount | Measured flow exiting the section at the downstream end (veh/time-step) |
| UpstreamDensity | Measured density at the upstream location (veh/km/lane) |
