Curbing High Rate of Accidents on Nigerian Roads Using High Speed Protecting Devices

##article.abstract##

The objective of the United Nations decade of action for road safety 2011-2020 is to reduce the projected number of road fatalities worldwide (1.9 million in 2020 on post trends) by 50%. The costs to society of road crashes are substantial and constitute a major burden for economies. Although no common international approach to assess crash cost has been agreed, estimations range from 1 to 30% of GDP, depending on the methodology used, but could grow significantly as research on the consequences of most severe injuries improves. Prior to the establishment of FRSC in 1998, World Health Organisation adjudged Nigeria as the most dangerous Country in the World to drive a motor vehicle. This necessitated the Federal government to address the situation by creating a statutory agency located at the Presidency, as Nigeria’s lead agency for road safety management and traffic administration. FRSC’s critical mandate is accident prevention and making roads safer. This paper looks at how high rate of accidents on Nigerian roads can be curbed using high speed warning and protecting device. The approach uses an input filter and amplifier which receives a regulated input signal from the spark plug and fed as an input to the tachometer which is a frequency to voltage converter, the output of the tachometer is fed as one of the inputs of the comparator whose other input is from the ignition coil of the vehicle, the output of the comparator is fed to the tone generator which is designed using a free running multivibrator. The tone generator is triggered as the set speed of the vehicle at the comparator circuit is exceeded, signaling that the speed is high and must be reduced.
