世界经济的波动极大地影响了燃料价格，而污染和气体排放不断增加，对全球变暖产生了负面影响。车辆网络提供了一种有前途的方法，可应用于运输系统以减少燃料消耗和排放。有趣的应用之一涉及向接近的车辆发送信息的交通灯信号。根据该信息，接收消息的车辆会将其速度调整为称为推荐速度（SR）的速度，该速度有助于车辆减少油耗和排放。在本文中，我们提出了一种优化模型，其目标是最大限度地减少燃料消耗和排放。能够达到这个目标的速度就是最佳SR。我们还提出了一种有效的启发式表达式来计算最佳 SR 的接近最佳值。
The volatile world economy has greatly affected fuel prices, while pollution and gas emissions are increasing to negatively impact global warming. Vehicular networks offer a promising approach that can be applied in transportation systems to reduce fuel consumption and emissions. One of the interesting applications involves a traffic light signal sending information to approaching vehicles. Based on that information, the vehicle receiving the message adapts its speed to a speed called the recommended speed (SR), which is the speed that helps the vehicle to reduce fuel consumption and emissions. In this paper, we propose an optimization model with the objective of minimizing fuel consumption and emissions. The speed that can achieve this goal is the optimum SR. We also propose an efficient heuristic expression to compute near-optimal values of the optimum SR.
