The rapid increase in the occurrence of road accidents in Nigeria requires the
deployment of real time techniques that is equipped to reduce one of the critical
factor that have been identified by the Federal Road Safety cooperation of Nigeria
(FRSC) that constitute the major cause of road accidents which is over speeding. This
was achieved through the design and implementation of real time vehicle speed
monitoring system using cellular signal along the travelled path. A data acquisition
device was developed to capture in real time the signal strength and geospatial data
(longitude and latitude) along the travel path which is used in determining the speed
of the moving vehicle. The acquired data was correlated with data obtained from
standardize equipment to establish the integrity of the data, the data was then used to
develop the algorithm by obtaining equation for the path-loss gain in terms of signal
strength against distance. Equation for the base stations covering a distance of 10km
were obtained for analysis. Consequently from the equation, the distance from two
locations along the route can be determined from corresponding signal strength
values, the average speed results for the drive test, new Model and using Latitude and
Longitude are compared as followed 88.05km/hr, 75.67km/hr and 88.2km/hr respectively. With this a new paradigm shift in vehicular speed management is
developed based on Cellular signals for real time vehicular speed determination.
