The Influence of Travel Time on Accessibility in Lagos Island

Abstract

The aim of this paper is to establish the influence of time on accessibility in Lagos Island, Nigeria. It was observed that generally, average driving speed was observed to be lower over short than over long distance routes. High speeds tend to be concentrated within a distance band of over 2.7km but beyond 6.0km average driving speed is low probably the result of interruptions in route. However, the mean driving speed for all nodes of thenetwork was calculated to be 0.31kmpm approximately 19kmph. The average driving speed was found to be significantly related to the link distance, with a correlation value of (r = 0.76). Based on the findings, recommendations were proffered that would reduce cost, time and accessibility will increase.
