Table 2
The distribution of feature vector of different driving types in a congested 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 | 18.91 | 4.07 | −0.03 | 0.3 | 2.81 | 1.05 | −1.32 | 5.2 | 0.01 | 0.95 | 56% | | 2 | 7.98 | 3.17 | −0.03 | 0.25 | 6.91 | 10.24 | 1.97 | 4.72 | 0.05 | 0.9 | 33% | | 3 | 14.36 | 6.42 | −2.15 | 0.71 | 4.84 | 10.41 | 0.07 | 5.01 | 2.3 | 1.06 | 12% |
