Abstract


The economic growth of a country is somehow dependent on the road network of such country and for the highways to be very effective, its geometrical features must be in line with required standards. A study for the effects of geometrical features on highway was conducted on Ado-Ikere road, Nigeria. The paper therefore looks into the critical points where accidents occur frequently along the road. Some geometrical features on these points were examined and it was observed that the medians measured 1.00m to 2.00m instead of the standard of 5.0m while the shoulders measured between 1.50m to 2.7m instead of 2.75m. The specified drainage design width of 3.00m ranges between 0.60m and 0.63m when measured and the right of way of 60.00m standard value ranges between 25.50m to 45.00m while the sight distance of 150.00m for the design speed of 100km/h ranges between 38m

Author Keywords: Effect, Geometric Design, Highway, Safety, Ado.
