ABSTRACT:

The paper describes the structure of road network development 1n llorin between 1963-1999 This was done by determining the network pattern of the city for the study period and identifying some socio-economic variables considered to be responsible for road network development to build models of network structure. Data on road network pattern of the city were acquired through mapping from sequential aerial photographs and land use maps of llorin. Data on socio-economic variables considered to be responsible for road network development were collected from State Ministries, Parastatals, Local Government offices and National Population Commission. Using graph theoretic concept measures of network development for the city were determined. Multiple Regression procedure was then used to develop models of the structure of road network development of the city. The results showed that the identified socio-economic variables are important in the explanation of road network development in llorin.
