ETS is the emergency traffic light system. This traffic system will be building for the emergency cars such as ambulance, police and fire cars. On the other hand, the system will have minor and major complexities. Some of the complexities include programming the system, programming the systems will contain huge coding statements, which will present the system with major difficulties, which are also hard to manoeuvre. For example, to distinguish between the normal car and the emergency cars such as ambulance, the systems must select the right statement to let the emergency car pass in a safe way. The emergency car also has the right of way compared with the normal cars and the coded statements in the programme should be programmed in such a way that there will not be any problem that may cause delays on them. The police cars also will have some privileges as the emergency cars and the system needs coding to reflect that. Coding will also contain the normal traffic light system process, which includes allowing for pedestrians to cross and the passenger service vehicles. The new trappings in the coding system may therefore affect the system by slowing its functions and lead to slow down in loading which may occasion undue delays (David, Cleland, Ireland, 2006, p.199). Moreover, the server of the emergency traffic system should have a message structure that lets the main coding system recognize whether it is running properly or not. This will allow for detection of malfunction, system failure or breakdown altogether which may lead congestion when the right commands are not being executed for the traffic and road users to follow forthright. This kind of message structure will be complex to check out when coming up with the right plan by the emergency system designers. Another complexity is that catching a different car by the system will be a big problem besides the main tribulations, which usually face the normal lighting system; this problem might lead to congestion, traffic jams and in reality many car accidents, which was not the case before the introduction of the new system (Kerzner, 2010, p. 5). The network used in the emergency traffic system is indeed a complex issue. Using the wireless system other than the main service providers may not connect accurately. Use of other service providers other than wireless has the advantage of ensuring right connectivity, as the signals are easy to detect in comparison to the wireless system of network. Wireless system of network might be cotted off because of the other signal network on the roads such as the telecommunication connectivity. Furthermore, building wireless connectivity to the point of having the right signals effect is quite complex. The alternative to wireless connectivity is use of fibre optic kind of network connection. This will be more expensive and tough approach to go for. There are various factors considered in attaching the fibre optic cable option. One of the main factors is the landscape of the roads. The connection is depended on the landscape of the roads, and therefore setting up the ETS might be tough and a hard task on an inclined and disinclined infrastructure thus requiring very smooth and plain kind of terrain. Contrary to the assertion that the ETS system is an easy go in the market, advertising the ETS system might be tough and consequently difficult to sell in the market. Not many companies will want to invest in such a venture, which is mi
