This study aimed to explore the effects of type and specifications of bus stop on bicycle speed and cycle track capacity. This paper investigates the traffic flow operations of tracks at basic sections, curbside stops, and bus bays by video recording. T-test and comparative study were used to analyze the influences of stop types on bicycle speed and capacity of track. The relationships between stop specifications and speed and capacity of track are analyzed with correlation analysis. The main results are as follows: (1) Without passengers crossing, bus bays have significant impact on bicycle speed, while it is not for curbside stops; (2) except platform length, there are strong negative relationships between bicycle speed and density of platform access, total width of platform accesses (TWPA), total width of platform accesses-to-platform length ratio (TWPA-to-PL ratio), total width of platform accesses-to-track width ratio (TWPA-to-TW ratio); (3) curbside stop and bus bay reduce track capacities by 32% and 13.5% on average, respectively; and (4) in contrast to bus bays, curbside stops have more significant impact on capacity of track, which also presents in the influence of the setting parameters of stops. Based the results above, some suggestions on stop specifications are finally proposed.

In response to multiple derailments involving hazmat trains, in early February 2020 Transport Canada released ministerial order (MO) 20-02, imposing speed restrictions of 20 to 25 mph on trains transporting a sufficient quantity of hazardous material. Since much of the North American freight network is used by multiple train types, the extreme speed heterogeneity created by this mandate substantially reduced train performance. Although this order was replaced within 2 weeks by new speed restrictions that were in turn replaced in May, MO 20-02 introduced the most extreme levels of train speed heterogeneity. The research team investigated the corresponding capacity effects to better understand the effects of train speed heterogeneity at low speed and inform agencies on future speed restrictions in this range. Using Rail Traffic Controller and General Train Movement Simulator, we quantitatively investigated the capacity loss from these speed restrictions and found that MO 20-02 can double or triple average train delay and lead to mainline capacity loss in excess of 60% on a representative single-track mainline.
