Table 1
The distribution of feature vector of different driving types in an unblocked traffic state.
| | Type | Average speed of vehicle
(m/s) | Average acceleration of vehicle
(m/s2) | Average headway
(s) | Average velocity difference
(m/s) | Average acceleration difference
(m/s2) | Sample proportion | | Mean | STD | Mean | STD | Mean | STD | Mean | STD | Mean | STD |
| | 1 | 30.5 | 8.43 | −2.09 | 0.72 | 2.42 | 1.06 | 0.19 | 5.95 | 2.14 | 1.18 | 15% | | 2 | 28.32 | 7.86 | −0.05 | 0.31 | 2.62 | 2.11 | 1.43 | 6.31 | 0.1 | 0.9 | 65% | | 3 | 30.17 | 8.4 | 1.35 | 0.88 | 2.52 | 1.37 | 0.8 | 5.94 | −2.07 | 1.15 | 20% |
