The increase in the number of private vehicles causes several transportation problems, such as congestion, longer travel times, and delays and queues. As a result of congestion, road users tend to choose the best route. The best route is the route with the minimum travel time and the lowest cost. In the four-step modeling of transportation (Four Step Modeling), the route selection stage is the last stage. Route selection modeling can identify the route that will be used by each driver so that finally the number of movements on each segment is obtained. The purpose of the literature review is to review the basic concepts of choosing an economical route. The research method is carried out by conducting a search on the results of scientific publications regarding the selection of routes that have economic value. Each journal that has been selected based on the criteria, limitation of the scope of the journal published in 2009 to 2020 is analyzed and a conclusion is drawn. The results of the review show that the factors influencing travellers in choosing a route are travel time, time value, travel costs and vehicle operational costs. Other factors that influence route selection are smoothness and socio-demographic factors which include gender, age, occupation, and monthly income. However, freight transport tends to be more concerned with distance and travel costs. Conclusion: route selection is strongly influenced by internal and external conditions
