Discuss about the Report for System Signs Help and Engineering.
System design is the procedure to define the components, data, architecture, interfaces as well as modules for a particular system in terms of satisfying specified requirements (Ross, Rhodes & Hastings, 2014). On the other hand, the system lifecycle is a proposed system’s view that addresses all of the phases of its presence to incorporate phase-out, disposal, retirement, maintenance, support, operation, distribution, construction, production, design, development as well as conception (Themistocleous et al., 2014). This report is mainly aimed to critically analyze the process of system design of the light rail network construction. AT or Auckland Transport is making an investigation on the construction of light rail network as a way for retrieving the traffic congestion on the busy streets as well as quickly getting more people around Auckland (De Weck, Ross & Rhodes, 2012). Therefore, in order to specify the construction as well as the constructional features of this project, the entire system lifecycle of this project including all of its phases such as conceptual system design, Preliminary System Design as well as Detail Design and Development are aimed to be stated in this report.
Conceptual System Design
The conceptual system design is important as it sets the direction for the Management Information System (Zeigler & Mittal, 2015). It is very important that the managers in a project participate heavily and seriously at this specific stage (Brown et al., 2016). This phase in system lifecycle is also known as high level design, gross design or feasibility design.
The major objective of this particular project is to overcome the problems or the consequences of the traffic congestion on the busy roads of Auckland (Gable, 2015). Therefore, reducing traffic congestion is the major and the primary need of this particular project. On the other hand, less consumption of fuel as well as the carbon footprint and the lower carbon emission is another two very important needs of this project, which are expected to be met with the help of the proper execution of the construction of light rail network (Malins et al., 2015). In addition, safety is the most important need for this project because the roads accidents are becoming vulnerable day by day.
This project of constructing the light rail network is feasible enough as it has huge practicability in terms of its benefits. The implementation as well as the execution of this project would result in several significant benefits for people in Auckland (De Weck, Ross & Rhodes, 2012). This project has been planned in order to meet some objectives or some essential requirements of people in the country (Shoval et al., 2016). As per the practicality, the proper execution of would be feasible enough to meet all the objectives set at the time of planning this project.
System Requirements Analysis
There must be some system requirements for the implementation of the project of constructing light rail network in Auckland. The major system requirement for this particular project is the proper and the accurate designing of railway construction as well as the entire rail systems (Hatchell, Mauss & Silvers, 2014). Without the proper implementation or design of the railway construction, it would not be possible to execution such crucial project. The system assurance is also another significant system requirement for this particular project to be executed (Knight et al., 2015).
There are several system specifications of the light rail network implementation project. These are as follows:
After the completion of the construction of the light rail network, the capacity would be increased that is up to 450 people per vehicle at a frequency of one every 2.5 to 10 minutes (Sharples, 2016).
The light rail network would also be able to ensure the safety benefit after the completion of this project (Cerri & Terzi, 2015).
The successful execution of this project would also be able to reduce the operating costs
Most important factor is that the execution of this project of constructing light rail network would be able to reduce congestion.
Apart from that, it would also be able to increase the productivity as well as the economic growth (Faulkner et al., 2015).
The execution of this project would also be able to give more reliable, simpler as well as faster services.
Preliminary System Design
At the time of this stage in system lifecycle and subsystems that perform the functions of desired system are specified as well as designed in compliance with the specification of the system (Ross, Rhodes & Hastings, 2014). Interfaces among the subsystems are demonstrated and the entire examination as well and the requirements of evaluation (Themistocleous et al., 2014). During the completion of this particular stage in the system life cycle, the specification of the development is produced, which is enough for performing the detailed and completed development as well as the design of the project (De Weck, Ross & Rhodes, 2012).
Functional analysis and allocation
Functional analysis is that basic tool of the process of design for exploring new projects as well as their constructional architectures. In addition, the functional analysis as well as allocation is a top-down approach to translate the requirements of system level into detailed performance and the functional criteria of design (Zeigler & Mittal, 2015). Therefore, in case of this constructional project of light rail network, a well-structured architectural framework should be established as well as designed. Hence, while implementing the framework, the new Light Rail Transit is also required (Brown et al., 2016). On the other hand, as per the functional analysis, the positive perception as well as the attitudinal factors of the Light Rail Networks can be related to the factors such as their sophisticated, clean and modern ability as well as appearance for blending into the low population level and urban environment (Gable, 2015). Apart from that, a certain population threshold would be appeared at the time of the execution of the project below that the light rail network would effectively function. Therefore, it can be considered as a major requirement allocation for the project to be executed in order to construct the light rail network.

The functional or the development specification of a particular project in software development as well as in system engineering is actually a document that can specify the features that a component or a system has to perform (Shoval et al., 2016). Therefore, in this scenario, such a document of development specification can easily be maintained that would specify the features of the light rail network construction. The light rail network, which is going to be constructed in Auckland, would be potentially implemented as well as investigated in several stages (Hatchell, Mauss & Silvers, 2014). In other words, there are several development specifications for the project of constructing the light rail network. These are as follows:
This project of the construction of light rail network can give the services with high frequency.
The service reliability of the project of the construction of the light rail network in Auckland is near about 100 %, which is achieved across the priority of traffic signal as well as dedicated tracks (Knight et al., 2015).
In this project, the fleet of the light rail vehicles, which are electric-powered with the low-floor design that is accessible with the potential for every 450 people.
Detail Design and Development
This particular stage in the system life cycle incorporates the implementation of the detailed executions that brings the preliminary designing activities into a completed form of specifications (Cerri & Terzi, 2015). This work also incorporates the interface specifications between the system as well as its intended environment as well as the comprehensive evaluation of the support requirements, maintenance requirements and the system’s logistical requirements. The detailed development as well as design is responsible to produce the material specifications, process as well as the product and can also lead to substantial changes to the specification of development.
As the detailed design of this project of constructing light rail network is concerned, thus it has to be stated that the light rail network in Auckland would be implemented potentially in several stages (Chen, Ames & Vivekanandan, 2014). First of all, at the initial phase of the construction of the light rail network, high frequency services would be maintained. Secondly, this construction project would also maintain a complete service reliability that is the service reliability would be close to 100 % (Faulkner et al., 2015). On the other hand, during the construction of the project, accessible floor design would be done with the capacity for 450 people. Most of the routes of light rail are proposed for traveling along with the road centre that is the median alignment. There are several connections would be built in order to execute this project of the construction of the light rail network. These are as follows:
- The Wynyard-Quarter Connection
- Dominion Road to Queen Street
- Mt Roskill to Down Dominion Road
- Sandringham road Line
- Wider Light Rail Network
The execution of the project to construct the light rail network would:
- Be capable of improving the access around and into the isthmus as well as city centre, by mitigating the future as well as the current issues in the rapidly growing city in Auckland (Sharples, 2016).
- Be able to improve the resilience as well as the efficiency of the transport network of city centre and isthmus.
- Give a sustainable solution of transport that can minimize the impacts on environment.
- Contribute significantly to shaping as well as lifting the economic growth of Auckland.
- Positively contribute to the safe, vibrant as well as livable city.
Revision of development specification
The development specification should be improvised so that the project execution can be successfully implemented (Hatchell, Mauss & Silvers, 2014). Therefore, most of the routes of the light rails have been proposed in this project for travelling along the road centre that is the middle alignment. The median alignment or the middle alignment with the side platform stops is the fastest as well as the simplest solution for the operations of the light rails as it:
- Can minimize the communication with the pedestrians as well as the cyclists.
- Can also permit for the higher speeds of operations (Cerri & Terzi, 2015).
- Is able to eliminate the impact of the slowdown of the road traffic for turning left.
- Can also reduce the traffic congestion by permitting the light rail for travelling separately.
- Reduces the influence on packing
Conclusion and Recommendations
After the entire discussion implemented in this report, it can be seen that the entire system design of the project of constructing the light rail network has been successfully illustrated in this report. With the help of the system design of this construction project of light rail network, each phase in the system lifecycle has clearly been discussed as well as implemented in this report. This report has successfully illustrated each step in all of the stages of the system life cycle of this particular project in a very clear and an understandable manner so that all the activities for executing the project can be understood very easily.
There are few recommendations those should be followed by the engineers as well as the project managers to overcome some crucial issues. These are as follows:
A proper timeline should be maintained in order to complete the execution of the project. The engineers and the project manager should fix a proper timeline and they also have to try to maintain that timeline as this project can be the medium to reduce traffic congestion.
On the other hand, the project managers should think about the alternative way out to reduce the problem of power consumption as the light rail network can lead to power consumption.
