  Modern technologies have become an evident solution to reduce undesirable highway casualties and fatalities. The convergence of Wireless Sensor Network (WSN) and telematics creates the opportunity to develop cost effective and easily manageable highway safety services for developing countries. In this study, the architecture of a Smart Highway System (SHS) is designed using WSN. The SHS increases highway safety by early collision warning, detecting violation of speed limit and automatic reporting of unnatural events like road accidents. The network for the SHS is self-constructed using the proposed algorithm automatic route initialization, which inherently detects sensor node failures and increases system stability by re-constructing the network. To construct the SHS, prototype sensor architecture is designed to detect velocity and moving direction of vehicles using a noise free weight threshing technique in a single package. The sensor readings and warning signal of base station propagate through the network using the data model of the TinyDB and reverse modification process of Directed Diffusion. An exhaustive simulation was performed to analyze the effectiveness of the system and to find relationship among hop-counts of the network, average distance of the deployed sensor nodes and the highest manageable vehicle velocity by the SHS. The simulation result shows that if number of hop-counts increases then the spacing among the sensor nodes on the roads should be increased. The correctness of the proposed SHS system is exemplary to develop new applications using WSN for developing countries.
