Descriptions of the explanatory variables.
| Variable | Descriptions |
| (m) | The size of the offered gap of merging vehicle | (m/s) | The speed of merging vehicle at offered gap. | (m) | The longitudinal position of the merging vehicle to the start of the auxiliary lane. | (m/s) | The speed difference between the putative leading vehicle and the merging vehicle at offered gap . | (m/s) | The speed difference between the putative following vehicle and the merging vehicle at offered gap . | ā | Existence of a lead vehicle in the merge lane. If there is a lead vehicle in the merge lane, ; otherwise, . | (m) | Lead gap of merging vehicle in the auxiliary lane at offered gap . | (m) | The speed of the leading vehicle in the auxiliary lane at offered gap . | (m/s) | The speed difference between the leading vehicle in the auxiliary lane and the merging vehicle at offered gap . |
