Abstract

With a human population of over 5 million, traffic congestion is one of the perennial urban problems confronting Lagos City, Nigeria. Many decongestion approaches had been attempted including vehicle movement restriction using odd-even registration as criterion, construction of billion dollar ring-roads, traffic planning through the installation of traffic lights. In this study, the vehicular carbon monoxide emission at one of the city's traffic light-control road-way junctions is modelled and measured using an automated NDIR system. The traffic flow at the intersection was characterized. A PC-version of USEPA's C ALINE model implemented by Trinity Consultants CAL3QHC) was used in predicting the CO concentrations nea
