The sec comprises eight digital cameras to be deployed in rotation at 75 selected sites distributed along the expressways and strategic routes , while 12 digital cameras for the rlc will be mounted on a rotational basis on 60 enforcement sites at selected road junctions throughout the terrority 侦察车速数码摄影机系统包括八部数码摄影机，轮流在本港各快速公路及主要道路上的七十五处地点进行执法。至于冲红灯数码摄影机系统则包括十二部数码摄影机，轮流在全港六十个指定的道路交界处使用。
However , some improvements have been made for the distributed rc model , the precision ca n ' t attain the request due to the influence of parasitic effect especially the increasing inductance with the development of interconnect technologies in deep - submicrometer region . so these influences must be taken into consideration and the building of new distributed rlc model for interconnect delay and crosstalk becomes more importance . according to this model , two cases , that is , cmos driving transmission line and interconnect line between chips have been analyzed 对传统的分布rc模型进行了改善，但随着互连向深亚微米级发展，寄生效应的影响尤其是电感的影响，必须考虑，因此建立新的rlc传输模型是很必要的，本文提出了这种新的互连模型，并对cmos驱动互连线和芯片之间互连两种情况进行了分析，验证了延时模型是可靠和精确的，并对延时的改善起到了指导作用。
