Many Vehicular Ad-hoc Networks (VANETs) applications require that each vehicle knows precisely its current position in real time. The Global Positioning System (GPS) is technology most widely used to determine the positioning of vehicles in VANETs. However, the GPS has several drawbacks, one of them is the lack of accuracy of the measurement of impact is the most unacceptable disadvantage. In this work, we propose a roadside unit- based localization scheme to improve the accuracy level of the vehicles' position for VANETs. In this way, each one of roadside units fix the relative position error and informs all vehicles that are within of the coverage area. The proposed solution requires few roadside units, which represents a low-cost of deployment, and it was able to reduce GPS error in this critical area from 7.21 m to 0.74 m.
