Project Brief

A road authority has retained you as the due diligence consultant to advise on traffic and transportation issues relating to proposals for a new estate development in England. The project is aimed at promoting sustainable development and economic growth to reduce poverty.

Specifically, you are required to:

• Provide pavement design advice for a new highway to accomodate the anticipated traffic to be generated as result of the new development
• Assess the traffic impact of the proposal on the area, including an evaluation of the capacity of the existing priority T-junction to accommodate the generated traffic
• Assess the pedestrian safety of the existing community near the proposed development and recommend appropriate mitigation measures.

Relevant portions of the Design Manual for Roads and Bridges (DMRB) should be consulted for this assessment. It is expected that completing the coursework evidences achievement of the module learning outcomes (LOs) and also demonstrates alignment with UK-SPEC outcomes needed for CEng/IEng registration. Further additional information and requirements for the new development that could assist you in your assessment are the following:

Pavement Design (LOs 1, 3, 4, 6) (50%)

A section of West Ham Lane in the Newham borough of London (Figure Q1.1), is to be redesigned as new construction to accommodate increases in vehicle traffic as a result of the rapid development the area is experiencing. Traffic estimates from the Department for Transport ((DfT) for the road section is summarized in Table Q1.1. Design a pavement section based on the DMRB procedures to accomade the given traffic. At a minimum, your solution must include determination:

a. Design traffic in appropriate units (10%)
b. Appropriate foundation class (10%)
c. Pavement thickness assuming a fully flexible conventional pavement (10%)
d. Carbon footbrint of your design in terms of CO2 emissions (10%)
e. Strategies to future-proof your design to address climate change (10%)

For the pavement foundation assume a clayey subgrade with design CBR of 5%.

Use the sample cabon emissons data discussed in class. Assume a pavement design life of 40 years. Use the performance foundation design.

Show all your work in detail so your answer can be checked.

Table Q1.1. Traffic data for northbound West Ham Lane road in Newham, Lndon

Geometric design (Los 3 and 6) (50%) The major road is an inter-urban road which is expected to have a typically interurban seasonal variation pattern. The traffic information available from the traffic model is the expected 2-way 24-hour AADT on each road for the design year as shown in Figure Q2.1. Turning movements data is as shown in Figure Q2.2. Assume a tidal split with a 60/40 split with the entry flows from the west and south dominant. The geometric features of the existing junction is shown in Table Q2.1. On the basis of the forecasted AADT flows in the design year and accompanying geometric data, determine the:

a. Ratio of flow to capacity (RFC) of each turning stream of traffic and the assumed tidal split of 60/40. Indicate the critical delay per vehicle. (30%)
b. Briefly discuss the adequacy or otherwise of the existing junction to cope with the anticipated traffic due to the new residential. Propose, with justifications, any low cost solution(s) that could be used to address congestion at the junction. The use of roundabouts or traffic signals are not permitted in this instance. (10%)
c. Using the West Ham Lane as case study, provide evidence to support the assertion that that majority of accidents are likely to occur near junctions. State all assumptions and your approach including software used (10%)
