都市交通計劃을 위한 街路 및 ZONE 의 交通容量에 對한 硏究 : 論文(Ⅱ) 街路 및 ZONE 의 交通容量 = A Study on the Capacity of Urban Street or Zone for Urban Transportation Planning(Ⅱ)

다국어 초록 (Multilingual Abstract)

This study(Ⅱ) treated the calculation method of the capacity of urban street or zone.
The process of computation method that is shown in Fig. 1 is follows.
1. Classified intersections accroding to the existence or nonexistence of signal and calculated service volume(C??), average queuing time(T??) and average queuing volume(W??) for each intesection. (refer to equations (10), (16) and (23))
2. Calculated the overall travel speed(V??) between the adjacent intersections from the standard overall travel speed(V??) that is shown at table 6, the average queuing time(T??), and the distance(L??) between adjacent intersection for each service level.(refer to equation(19))
3. Classified the means of capacity for street or zone into the capacity that can pass over the street or the zone and the capacity that can be dealt in the street or the zone. And taked saturation degree and overall travel speed as the factors for deciding service level.
4. Taked the smallest capacity among a number of intersection capacities as the capacity(SC??) that can pass over the street in the case a given street is consisted of a number of intersections and through lanes. And taked the sum of the queuing volumes at the intersections and the volumes on the through lanes as the capacity that can be deal in the inner part of the given street.
5. Taked the sum of capacities that pass over the streets crossing the zone boundary as the capacity that can pass over the zone(ZC??) and taked the sum of capacities that can be deal in the inner part of the streets(ZW??) as the capacity that can be deal in the zone.
