Efficiency of Semi-Autonomous and Fully Autonomous Bus Services in Trunk-and-Branches Networks

Figure 7

(a) Total cost and (b) applicability of semi-autonomous bus with respect to different ratios between corridor and total travel time. Note that the top-left side of each curve in (b) indicates the preferable region of semi-autonomous buses, whereas the other side is for conventional buses. The dotted line gives the upper bound of , which is 0.63. Other parameters according to Table 2.
