Abstract. Vehicular transportation has received rapid growth in many areas thanks to the increase in population density and massive city expansion. Such advancement however leads to the loss of time, money and human lives due to many reasons including driver distraction and serious roadway conditions. Recent trends have shown improvement of vehicular safety on account of design and manufacturing innovations such as additional airbags and pre-collision detection and warning using sensors. Nonetheless, the national averages of fatality, injuries, and property damages due to roadway vehicular crashes still remain at high levels. For the purpose of saving lives, reducing fuel costs and travel time on road, it is demanded to have a vehicular communication system that rapidly learns about the environment and promptly respond and notify drivers for decision making. Our research in this paper aims to design a system that utilizes the communica‐ tions among vehicles in a Vehicular Ad Hoc Network (VANET) and roadside infrastructure-based devices. Our design and analysis indicate that such system can be applied to assist drivers in adjusting their driving for better safety and making route decisions to save time and fuel costs.

Introduction
The data released by the National Highway Traffic Safety Administration (NHTSA) in 2014 shows a total number of 32,675 fatal crashes in the United States. It can also be found in the same set of data that 2.3 million injuries from vehicle accidents were reported in the same year [1]. In addition to lives and injuries, two other major losses on road are time and cost of fuel, which are typical in cities and metropolitan areas where commuters loose great amount of time due to traffic congestions and road conditions during peak time for their weekday commuting. A study released in 2015 by the Texas A&M Transportation Institute indicates that annually the U.S. suffers a loss of $140 million due to time and fuel wasted in traffic congestions, and on average each commuter spends an extra 42 h and wastes 19 gallons of fuel caused by traffic and road condi‐ tions [2]. The Vehicular Ad Hoc Networks (VANETs) are designed and implemented primarily for improving road safety and driving efficiency. A VANET can be comprised of a mixture of two network topologies: infrastructure-based and infrastructure-less (ad hoc).
