In development projects, transport planning due diligence is a critical early component in ensuring that new sites are viable. One of the earliest and most important steps in the process is to assess site access feasibility. This involves determining how easily and safely vehicles, pedestrians, cyclists, and public transport users can access the site. Conducting this work early can help identify potential issues, mitigate risks, and ultimately reduce planning delays, costs, and uncertainty.

The Importance of Early Site Access Feasibility and Due Diligence
In the early stages of a development, ensuring site access feasibility is a crucial step. Early due diligence helps developers assess the suitability of access locations, the junction type needed for the development, and whether the existing transport network is likely to be able to accommodate the expected growth in demand, particularly traffic.
An early high level review helps identify potential problems such as inadequate visibility, unsafe access points, or insufficient capacity to handle projected traffic volumes.
Identifying these issues early on allows developers to plan effective mitigation measures, such as access upgrades or any changes that may be needed at local junctions, and consider these in projects budgets and viability. This can prevent costly delays during the planning process and most importantly ensure that the development can be delivered to meet commercial objectives.
Key Considerations in Site Access Feasibility
When evaluating site access feasibility, several factors need to be taken into account. The type of vehicular access required will depend on the nature of the development and the existing road network. For example, a priority junction, roundabout, or signals may be necessary depending on the level of traffic generated by the development and the characteristics of the local roads.
Another crucial factor is ensuring multi-modal access. This means not only considering vehicular access, but also designing for pedestrian access, cycle access, and proximity to bus stops and services. Providing safe and convenient access for all modes of transport is increasingly important in meeting sustainability goals and reducing reliance on cars. In some cases, this may involve creating new pedestrian crossings, upgrading cycling infrastructure, or improving public transport links to a site.
Benefits of Addressing Site Access Early
One of the primary benefits of conducting transport planning due diligence and site access feasibility assessments early in the project is the ability to mitigate risks. For example, identifying a suboptimal access location with poor visibility or dangerous traffic flows can lead to changes in the design or relocation of the access point. This reduces the risk of road safety concerns being raised later in the process, which could delay planning approval or lead to costly redesigns.
Additionally, early assessment allows for the optimisation of new access or improvements to existing access, ensuring that the development can be integrated into the local transport network. This includes determining the most appropriate junction type for the development, whether that be a simple priority junction, a more complex roundabout, or signalised junctions. Each option has different implications for traffic management and cost, making early consideration vital.
Reducing Risk and Saving Time
In conclusion, transport planning due diligence and site access feasibility are essential steps in ensuring the success of any development in the UK. By conducting these assessments early, developers can identify potential issues, implement access upgrades or new infrastructure as needed, and ensure the development meets all planning requirements. This proactive approach reduces planning risks, saves on costs, and streamlines the overall project timeline.
