There are two finite simplicial complexes associated with a road junction and there is a correspondence between the structure of these complexes and an intuitive evaluation of the junction's ability to carry flows. This intuitive feeling is made well-defined by the introduction of an order relation between junctions according to the flows they can accommodate. In comparing junction designs it is found that a relatively low dimension structure q-connected only for relatively small q is associated with a superior ability to accommodate flows, and an illustration is given of the application of these findings to a complicated interchange and an experimental roundabout. The structural analysis was performed on the Essex PDP-10 computer using lethan one minute computing time and 2K store for a complicated intersection showing there are no computing problems to be overcome.
