Route assignment

Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in <a href="/facts/Transport_network/xtFgRh60">transportation networks</a>. It is the fourth step in the conventional <a href="/facts/Transportation_forecasting/Yudqw5BW">transportation forecasting</a> model, following <a href="/facts/Trip_generation/WMCpet7b">trip generation</a>, <a href="/facts/Trip_distribution/jmX5xpTj">trip distribution</a>, and <a href="/facts/Mode_choice/2gGbT9pw">mode choice</a>. The zonal interchange analysis of trip distribution provides origin-destination trip tables. Mode choice analysis tells which travelers will use which <a href="/facts/Transport_mode/chlfguRU">mode</a>. To determine facility needs and costs and benefits, we need to know the number of travelers on each route and link of the network (a route is simply a chain of links between an origin and destination). We need to undertake traffic (or trip) assignment. Suppose there is a network of <a href="/facts/Highway/2nxmEmgX">highways</a> and <a href="/facts/Public_transport/DXhqazz5">transit</a> systems and a proposed addition. We first want to know the present pattern of <a href="/facts/Traffic/cHx4tMo1">traffic</a> delay and then what would happen if the addition were made.
