未来的智能交通系统（ITS）将需要无线车辆到基础设施（V2 I）通信。这种无线链路可以通过几种技术来实现，例如数字广播、蜂窝通信或专用短程通信（DSRC）系统。分析的覆盖范围和容量的要求时，这三个系统中的每一个被用来实现V2 I链路。我们表明，数字广播系统固有的容量有限，不适当的规模。此外，我们表明，通用移动的电信系统（UMTS）可以实现V2 I链路使用专用信道（DCH）或多媒体广播/多播服务（MBMS），以及混合的方法。在任何情况下，这种V2 I系统都可以很好地扩展，并且容量有限。我们还表明，无线接入车载环境（WAVE）系统的规模以及，提供充足的容量，覆盖范围有限。最后，给出了一个直接的定量比较所提出的系统，以显示其缩放行为与用户数量和地理覆盖范围。
Future intelligent transportation systems (ITS) will necessitate wireless vehicle-to-infrastructure (V2I) communications. This wireless link can be implemented by several technologies, such as digital broadcasting, cellular communication, or dedicated short-range communication (DSRC) systems. Analyses of the coverage and capacity requirements are presented when each of the three systems is used to implement the V2I link. We show that digital broadcasting systems are inherently capacity limited and do not appropriately scale. Furthermore, we show that the Universal Mobile Telecommunications System (UMTS) can implement the V2I link using either a dedicated channel (DCH) or a multimedia broadcast/multicast service (MBMS), as well as a hybrid approach. In every case, such V2I systems scale well and are capacity limited. We also show that wireless access in vehicular environment (WAVE) systems scale well, provide ample capacity, and are coverage limited. Finally, a direct quantitative comparison of the presented systems is given to show their scaling behavior with the number of users and the geographical coverage.
