Mobility of the Poor in Akure Metropolis: Income and Land Use Approach

Nigeria being a developing economy still has a high percentage of low income earners. Mobility and modal choice affect us all in our daily life whether we are commuting to work or for recreational purpose. Catering for the effective and efficient mobility of this unique set of low income earners is a task for transport planners. This research assessed the mobility of the poor using land use and level of income. The study area was divided into six zones based on the land use configuration.Income level, frequency of trip and the predominant modal choice for both work and business trip were evaluated. The result showed that the use of taxi and motor cycle in the study area is high. The low income group has the highest frequency of trip base on the level of income and land use. The result of this research will aid the government at all levels and policy makers in formulating a good transportation scheme for the low income earners now and in the foreseeable future. It will also provide policy makers with an improved understanding of the travel behavior of the poor and their preferred modal choic

Post-Independence Evaluation of Air Transport Safety in Nigeria

This research evaluates air transportation safety in Nigeria. Records of aircraft crashes in Nigeria were extracted from different archives to create a database of air traffic incidences within the air space of Nigeria since Independence. Statistical overview of air transportation accidents in Nigeria using accident data to examine a national trend in air transportation disasters was carried out. Results of the analysis showed that air traffic accidents in Nigeria have increased per decade with 2 incidences between 1960 and 1969, 27 incidences between 2000 and 2009 with an increasing trend in the preceding decades. Impacts of season on aircraft accident in Nigeria were less significant. Airplanes constitute larger proportion of aircraft involved in accident with 86% incidences, and 14% for helicopter. Passenger plane constitute the largest proportion with 46 incidences occurring in the commercial plane category while 8 and 2 crashes occur in Military and Cargo operation. Majority of the accidents in Nigeria occurred in Lagos with 14 crashes involving plane majorly, followed by Abuja (FCT) and, Kano and Rivers with 4 each. Year 2005 however has the highest number of plane incidences in Nigeria with 11 crashe

PERVIOUS PAVEMENTS FOR STORM WATER CONTROL

and to recharge underground aquifer. It could also be used to trap solids and keep pollutants from contaminating the water stream. This review of literature examines existing studies methodologies, technologies, advantages and drawbacks on the use of pervious pavement for stormwater control and aquifer recharge. The result of the review revealed that cement content, water-cement ratio and compaction level affect the mechanical strength of pervious concrete in rigid pavement construction. Due to the complex nature pervious properties of this concrete. Pervious concrete requires stricter quality control of the concrete mixture proportioning as compared with the conventional concrete as there are no standard specification for testing. Surface sweeping method of pore-clogging removal was ineffective in the improvement of the hydraulic conductivity of pervious pavements, as it can only help in the removal of surface debris and not sediments removal from deep voids. The development of this pavement is a positive way forward for stormwater management and aquifer recharge. It is a viable technology in the reduction of stormwater runoff and the concentration of pollutants

Assessment of the Engineering Properties of Modified Asphalt Using Aluminium Dross as a Filler.

Aluminum dross waste creates environmental burden for manufacturers and hence the need for its re-use. This experimental research assessed the engineering properties of modified asphalt using aluminium dross as a filer material. The aluminium dross used was obtained from a steel manufacturing industry. Elemental composition of the oxides was done using XRF equipment. Sieve analysis of the aluminium dross and the coarse aggregate was also assessed. Additionally, ductility, penetration, ball and ring and Marshall stability test were used in achieving the aim of this research. The outcome of the research revealed that 10-20% addition of the aluminium dross improved the stability of the modified asphalt. Physical observation revealed that the utilization of the waste stiffened the modified asphalt. The result showed that the addition of aluminium dross reduced the VMA. This will also increase the asphalt mix flushing. Additionally, at higher percentage addition of the waste the stiffness of the asphalt mix increases especially at a higher temperature. The use of this material will help in the reduction of solid waste and reduce the cost of management while reducing the cost of pavement construction in track with the trash to treasure drive
