Assessment regulations and academic integrity
The University rules on Academic Integrity apply to all submissions.The student academic integrity regulations contain a detailed definition of academic integrity breaches.
- You cannot knowingly permit another student to copy all or part of your work.
- You must not share your work with other students. This includes posting any of your work in z.
By submitting the report, you are confirming that:
- It is your own work except where explicit reference is made to the contribution of others.
- It has not been submitted for any module, programme or degree at Edinburgh Napier University or any other institution.

1.1 Assessment Overview
The overall aim of this coursework is to appraise a planned infrastructure development, opportunity it provides to improve the public health, and an understanding of different challenges and opportunities that an engineer can face. The study is focused on a town with heavy through traffic, in proximity to the one of the busiest highways in a developed country. The present road network is shown in Fig 1. The town has some black spots which have been the scene of several accidents in recent years. The through traffic (including a fair proportion of lorries) is growing heavier, causing noise and air quality problems for residents, and increasing severance as the road is getting increasingly difficult to cross. This is affecting the residents who have lived there for generations. This is also affecting the country’s economy as the through traffic must slow down to 30 mph to pass through the town, increasing travel time compared to free flow on a rural road (60 mph). To relieve these problems,a bypass is suggested, re-routing the through traffic away from the town.This is expected to decrease the travel time for through traffic and improve the living conditions in the small town. The proposed Bypass is shown in dotted line in Fig.2

(Bypass is shown as the orange dotted line)
Road C
Road A
Road B
Fig 3: Schematic of the Roads under Investigation0
The construction of the Bypass will result in reduction in traffic for Roads A and B. The decrease in the vehicular traffic gives an opportunity to make plans to reduce the high car dependence and encourage other modes of transportation which can be healthier and sustainable.You will need to make a plan with several measures to encourage/achieve this modal shift towards more sustainable and healthier mobility.You will need to roughly(no exact calculation or modelling required) anticipate the possible modal shift due to each measure and how that can improve the local environment, public health, and air quality. Road B is an A road type as per the UK Highways classification, whereas Road A is a B type road as per the UK Highways classification. You can make assumptions regarding the town transportation system, but you should clearly state any assumptions that you make. As the major traffic will be plying through the newly proposed
Road C, a new intersection is being considered at Point O (Intersection of Road A and Road B, to connect it with a nearby market town. Presently a) Roundabout and b) Traffic Signal are being considered at Point O. You need to critically appraise both junction types, in the context and make recommendations for the selection of a particular junction type at O.It is pertinent to mention that the council has recommended to construct a park and a new housing estate (350 dwellings ) within 1 km radius of Point O. All this should be drawn in the form of a schematic plan within a single sheet of paper (maximum size A2) sheet. This can be either hand drawn, or you can construct it digitally. For the hand drawn, you will need to scan it and attach it as a single file.
Input Data:
Scenario 1 (do-nothing)
Roads A and B passing through the town.
Scenario 2 (do-something) - with a New Bypass
Roads A and B passing through town. New bypass ‘Road C’ constructed.

1.2 Assessment Tasks to be completed by Students.
Tasks:
(a)Draw a schematic plan for introduction/encouragement of healthier and more sustainable transportation modes for the town.You will need to include the measures that you would like to introduce in the town to encourage people to use healthier and sustainable transporta- tion modes and explain how each measure is going to improve the local air quality.
(40 marks)
(b) Discuss the effect of employing Roundabout at Point O, and its corresponding road safety implications.Critically appraise roundabout design and standards presently being employed in UK. Discuss any spe- cial provisions for promotion of sustainable transport modes (only Bullet points).
(30 marks)
(c)Discuss the effect of employing Traffic Signal Control at Point O, and its corresponding road safety implications.Critically appraise Traffic Signal design and standards presently being employed in UK. Discuss any special provisions for promotion of sustainable transport modes (only Bullet points).
(30 marks)
(a) Academic skills support: In advance of submission, you can access the support of the academic skills team. They can help you with any aspect of the assessment that you might struggle with, that is not content related. For example, they can help with time-management, effective reading and note-making, and any aspect of academic writing that you might struggle with. This support is provided through workshops and individual appointments which are bookable online via MyNapier: Improve your Academic & Study Skills (napier.ac.uk). You can also directly email the Academic Skills Adviser, Hannah Awcock, h.awcock@napier.ac.uk for any specific academic skills support you require.
