Abstrak

Route selection is a major element of the network assignment model. This process is often also called
network tree building. In conventional route selection, each repetition will only produce one best path or
shortestpath. Using fuzzy systems approach, travel cost is modeled in fuzzy numbers. Fuzzy numbers are
numbers with certain upper-bound and under-bound limits. In fuzzy conditions, route selection process is
expected to produce several routes that can be nominated as the shortestpath. It means that in each repetition,
the finding algorithm will generate more than one best route, starting from the first best route, the second best
route, to the k best route. The next process is the trip assignment existing (demand side) on the transportation
network system (supply side) which will produce a route pattern and traffic flow. Traffic flow allocation
based on the series of best routes and degree of membership of fuzzy numbers.
