Abstract

In order to ensure sustainable transportation planning and management in Nigeria, it is imperative to have adequate knowledge of its traffic characteristics. This study, therefore, was carried out to elicit relevant traffic data for transportation planning and management, using the medium-city of Inisa in Osun State as a case study. Data were collected through observational survey and questionnaire administration. Data on volumetric counts were sourced through observational survey at two locations. In addition, a total of 800 households’ heads were administered questionnaire in the study area, using systematic sampling method. The data were analyzed using descriptive and inferential statistics. Results showed no significant variation in traffic volume throughout the week. The characteristics of the typical traffic flow in the town also followed the normal conventional traffic of early morning and late evening peak periods. The modal split of traffic indicated that motorcycle mode accounted for more than half of the total traffic in the town.  The possible implications of the traffic characteristics for transportation planning and management in Inisa town were categorized into four, namely safety, air pollution, noise and vibration. The article advocated stringent road transport policies coupled with the provision of safe transport facilities to enhance livable city.   Keywords: Medium-Sized City; Modal Split; Transportation Planning; Traffic Flow; Traffic Survey.
