Urban street network capacity reliability

摘要

A reliability measure of network capacity under node capacities has been introduced, using the concept of network reserve capacity, and compared with that based on link capacities. The measure incorporating node capacities suggested should be considered in reliability analysis of urban street networks. Note that the assumption that every origin-destination (OD) pair will have a uniform growth or decline in its OD demand is preserved, whereas relaxing this limitation can yield pictures regarding the spatial distribution of the demand pattern with non-uniform change, which can be especially useful in individual zone land-use development plans.
