| # Third-party code notice | |
| The driver-space inference routines in `driver_space_model.py` are adapted from [Yiru-Jiao/DriverSpaceInference](https://github.com/Yiru-Jiao/DriverSpaceInference), accompanying Jiao et al. (2023), *Inferring vehicle spacing in urban traffic from trajectory data*. The original implementation used `scipy.misc.derivative`; this version expresses its three-point central second difference directly and retains the supplied inference procedure and settings. | |
