About the Cover

The importance of intercity bus services in the world cannot be overemphasized as it enhances long-distant travel on the road. This study examined the factors influencing passengers’ choice of intercity bus operators in Lagos, Nigeria. To achieve this, five intercity bus operators were selected and a total of forty-six (46) bus terminus were sampled. Three thousand copies of questionnaires (3000) were distributed among the five intercity bus operators through the assistant of the terminal managers across the forty-six-terminal operated by the bus companies, two thousand six hundred and eighty-two copies of questionnaires (2682) were retrieved and found useable for analysis. Primary data were collected using structured questionnaire, the data collected were arranged systematically and coded to facilitate analysis and data were subjected to descriptive statistics evaluation. Multiple linear regression analysis was adopted for the study. Passenger’s choice of operator revealed that for ABC transport, advertisement, frequency of operator’s service, reliability of service and expectation of future price were the most significant factors influencing choice of customers to use the operator’s service. For CHISCO transport, it was observed that among the factors influencing passenger’s choice, the frequency of operators’ service has (β=0.883, p ≤ 0.05) is the most significant factor, reliability of service has (β=0.488, p ≤ 0.05), fare has (β=0.455, p ≤ 0.05).
