Abstract

Determination of transportation cost is important to ensure that the price paid by transportation users correctly reflects the true costs of providing transportation services. This study proposes one route transportation cost model. The model was developed in terms of operating cost: infrastructure cost: accident and congestion cost: and contingency cost;

In the application, data were collected from 200 auto vehicle users: oyo state ministry of works and transport and through review of previous works on: road maintenance and improvement works in oyo sate between 2000 and 2001: traffic count along Ibadan – Ilorin road: rates, dues, levels etc by auto users and fuel consumption, maintenance and parking data. The operation, infrastructure, contingency costs parameters were estimated using the data collected while the accident and congestion cost parameters were adapted from literature. The cost of transportation for mini buses and cars (passengers) per trip along Ibadan – Ilorin route was estimated as N426.00 and N585.00 per passenger per trip, respectively, with vehicle operating cost being major contributor.

Keywords: accident and congestion, contingency, infrastructure, auto transport users, transportation cost parameters.
