Design Feasibility report for a cycleway

University of the West of England – Centre for Transport and Society

UBGMFX-15-M Transport Infrastructure Design

Coursework Assignment A – Design Feasibility report for a cycleway

To be submitted: A succinct report of 2,000 words with appendices containing the designs

Weighting: 50% of the module mark

Submission date: 28th April 2022 at 14:00

The three calendar day grace period applies to this assignment, but you should plan to submit your work by the deadline.

This assignment addresses the following module outcomes

MO1 Apply design principles and standards to transport infrastructure geometric design problems

MO2 Apply design principles and standards to transport infrastructure construction problems

MO3 Generate a number of design options to solve an open ended problem

MO4 Synthesise specifications, standards and site conditions to develop final detailed solutions.

High level cycle route across the valley of the River Frome

Routes to cycle between UWE (and the North Fringe beyond UWE to the North West) and Downend (and its hinterland of Staple Hill and Mangotsfield to the east and south) and are not direct, as shown on the plan in Figure 1. There is a proposal to create a high level cycle bridge across the valley of the River Frome at or near the current location of the Ha’penny Bridge, as also shown on Figure 1.

Figure 1 Existing cycle routes between UWE and Fishponds and Downend.

Ha’penny Bridge

Via Blackberry Hill

Via Ring Road

The cycle route is proposed to connect College Road with Sheldrake / Begbrook Drive (near to Begbrook primary school). There are existing footpaths between these two routes as shown by the blue line in Figure 2. Note that the ring road cycle route carries 600 cycles each way per day, the majority of which are in the peak period. You should assume that the bridge will attract at least half of these cyclists and many more besides.

Ha’penny Bridge

Your task is to design the vertical and horizontal alignment of a cycle route between the end points of the proposed cycle route as shown in Figure 2. Only the end points and levels of the end points are fixed. You can assume that you are able to use any land that you need between these two end points apart from:

land shaded pink in Figure 2 (the old hospital site)

land coloured brown within the curtilage of Begbrook Primary Academy on Sheldrake Drive

land taken by the College Road allotments.

You need to accommodate pedestrians in your design, and these need to be separated from the cycle route by a kerb. You should view this video for reasons as to why this is important: https://vimeo.com/379255176/d0b6498c1b.

You will need to submit the following, which will form appendices to your design report:

Appendix D2.1: A design statement up to a single side of A4 that a) Describes the problem; b) explain why there are limits on horizontal curve radii and gradients for cycle traffic; c) note particular design requirements for those with adapted cycles and disabled people, including the visually impaired; and d) summarises the final design and remaining deficiencies in the design.

Appendix D2.2: A tabulation of the assumptions you have adopted for the design and calculations you have made based on these.

Appendix D2.3: A plan layout at an appropriate scale which shows the horizontal geometry of the proposed cycle route.

Appendix D2.4: A long-section at an appropriate scale which shows the vertical geometry of the proposed cycle route. A critical feature of the design is the level of the proposed bridge and this should be clearly stated. Also make sure you indicate clearly the approximate length of the bridge.

Appendix D2.5: A number of annotated sketches to describe the a) cross-section (with dimensions); b) materials to be used in the formation, surfacing and edging of the cycleway and footway; c) drainage solutions; d) lighting for the route. The annotations should indicate WHAT is proposed and WHY it is being proposed. (Please use the words WHAT and WHY in your annotations in capital letters to help differentiate these two parts to the annotation).

You should use Digimap to provide you with the necessary base mapping to create the design (http://digimap.edina.ac.uk/) and level information. Instead of making neat drawings for you plan and long-section, you may wish to use Civils3D.

Submission

You will submit a report the main body of which will be 2000 words in length discussing what you have learned from the two design tasks. This report will have appendices, exactly as lettered and numbered in the individual tasks above, which present the designs you have prepared. The report and its appendices will be contained in a single WORD file. The structure of the report will be as follows:

Section 1 of the report will be titled ‘Introduction’ and will summarise the content of the report in about one page.

Section 2 will be titled ‘Reflections on design processes’ and you will present your reflections on the cognitive processes used in developing design options, especially the way you defined the problem, were creative in developing possible solutions, and evaluated those.

References. A section providing the bibliography in alphabetical order for all the citations in the text and appendices.

The appendices, as listed above, in order.

Assessment Criteria

The work that you undertake will be assessed according to:

The clarity of your design statements (Appendix D2.1)

The appropriateness of tabulation of assumptions you make for the design (Appendix D2.2)

The appropriateness of the design as expressed in the layout plan and long-section (Appendices D2.3 and D2.4)

The quality of the thinking in relation to the nature of construction of the cycleway and footway (Appendix D2.5)

The quality of reflection in the main report on the design process

Compliance with requirement for a single WORD file submission
