14 Exhibit 23. The Modal Operational Inter-Relationships in the TCQSM, Second Edition. Mode Auto Transit Bicycle Pedestrian Auto Not Higher auto volumes may reduce reliability, but Not Not Applicable no estimation method is available in the TCQSM. Applicable Applicable Reduced reliability affects passenger loads. Auto volumes, street width, and signal timing affect street crossing difficulty which can reduce service coverage. Higher auto volumes reduce bus speed, which affects transit-auto travel time, but no estimation method is available in the HCM or TCQSM. Transit Not Higher bus volumes reduce bus speed, which Not Not Applicable affects transit-auto travel time. High bus volumes Applicable Applicable relative to bus capacity affect reliability, but no estimation method is available in the TCQSM. Bicycle Not No estimation method is available in the HCM or Not Not Applicable TCQSM for the effect of bikes on bus speed or Applicable Applicable reliability. Pedestrian Not Pedestrian crossing volumes affect right-turn Not Not Applicable capacity, which affects bus lane capacity, which Applicable Applicable affects bus travel time and reliability, but no estimation method is available in the TCQSM. Shaded boxes indicate weak or non-existent inter-relationships. No effect means that a change in modal volume has no effect on LOS as computed per the TCQSM.
