Much of the literature on exclusive bus lanes pertains to how these lanes might induce shifts in mode choice by prioritizing bus travel, sometimes at the expense of degrading travel by car; for example, see Basso et al. (1). A separate line of research theorized that the conversion of regular-use lanes to bus-only lanes can, in certain circumstances, improve travel for cars as well as buses, even in the absence of modal shifts (2). By removing buses from queues and putting them in their own, faster-moving lanes, target service frequencies can be maintained with fewer buses; thus, fewer bus...
