Abstract: The paper is aimed at examining the econometric modeling of passenger demand for international air transport in Nigeria Airports with the objective of examining the relationship between the international passenger demand in Nigeria airports and economic variables. 91.2% of the dependent variable can be well explained by the independent variables and the unexplained variables or the error term is 8.8%. The fact that the coefficient of explanation (R Square) is very high, this is a sign that there is a problem of multicolinearity and the Durbin Watson value (3.443) which is greater than 2 also signifies there is a problem of autocorrelation or serial correlation. The significance level of the computed test statistics is 1.29 which is more than the significance level (0.05), hence we cannot reject the null hypothesis which states that there is no statistical significant relationship between % change in international Passenger Traffic (Annual) and % change in economic indicators (Consumer Inflation Price (CPI), Naira value to Dollar and Gross Domestic Product). It is therefore concluded that the economic indicators cannot give a good forecast of international air transport demand because the model suffers from serial correlation, multicolinearity and insignificance of the test.

Abstract: One of the major causes of road accidents, crashes, mishaps and fatalities globally all over the world is drunk driving. Though driving under intoxication is illegal, even then people restore to such hard-core habits often. In order to combat such risky situation on road, technological innovation needs to be implemented in a cost-effective, efficient and legal manner. This paper discusses design, development and live-performance test of the prototype of drink and drive situation detection and alert cum vehicle control system to minimize road mishaps and enhance public safety on road. It also analyses the response of breath –alcohol semiconductor sensor with respect to variation in distance from source which is critical part of system design. Based upon the recent smart gas sensing and integration of satellite and cellular wireless communication technologies, the proposed device quickly senses the drunken state of the driver during start-up/driving by estimating the equivalent breath alcohol concentration level corresponding to the legally permissible state’s threshold blood alcohol concentration level. On detection of such situation, on-vehicle siren/audio alarm is activated to warn the persons on road and vehicle control system is triggered to lock ignition or stop the fuel inflow to the vehicle. Additionally, ‘alert SMS’ indicating drunk driver location, tracked by onboard GPS receiver, along with vehicle number is communicated remotely to authorized (family members, traffic police) mobile user using GSM cellular network to take appropriate action thereafter. The live experiment results highlighted the successful working performance of the device in-housed at the steering wheel of the vehicle with the drunk driver.
