Transport Planning Services

Our transport consultants produce Transport Statements, Transport Assessments, Travel Plans, Delivery and Servicing Plans and Parking Management Plans for a range of planning applications.

We also coordinate and manage traffic surveys and parking surveys. Our transport planning services include:

Transport and Development Planning

Provision of Transport Assessments/Statements, Travel Plans, Delivery & Servicing Plans and Construction & Logistics Plans to support planning applications for the redevelopment of sites.

Traffic Engineering and Modelling

Capability to design new highway layouts for a mixture of signal controlled, priority and roundabout junctions and model their capacity using tools such as Arcady, Picady and Linsig.

Road safety audits can be commissioned where required, with recommendations leading to improved highway layouts.

Travel Plans

Ability to deliver high-quality travel plans implementing sustainable travel patterns for various scheme elements – residential, school, health sector and workplace. This focuses on reducing the need to travel and the provision of high-quality alternatives to the car.

Our Transport Assessments and Travel Plans can incorporate PERS Audits to assess detailed conditions of pedestrian and cycle routes.

Traffic Surveys

Management and coordination of traffic and parking observation surveys along with result analysis.

Louise Smith, the leader of our Transport team, previously project managed the late TRAVL trip generation database and survey programme for London across six years, the surveys of which have since been incorporated into the TRICS software. She has also in her previous roles, been the Travel Plan Coordinator for approximately eight residential developments in London, the South-East and other parts of the UK.

Highways Infrastructure & Drainage 

AVAL provides a range of services covering all aspects of engineering and environmental consultancy services for Civil Infrastructure.  As part of this, our dedicated Highways Team can provide expert advice on a range of projects and planning applications for clients from a range of backgrounds.

We can assist you with all your highways and road access design and drawing needs. From the start of the project feasibility to detailed design stage we can provide you with full highways civil infrastructure consultancy support.

Our highways work is complemented by our in-house environmental and civil engineering colleagues who can assist with a number of other civil and environmental considerations such as flood risk, air quality, noise, contaminated land, daylight and lighting strategy, odour, vibration and design and access strategy.


Our Team

Louise Smith, our Principal Transport Planner and the Transport Team Leader has over fifteen years’ experience in transport planning/ engineering and project management for both the public and private sectors preparing Transport Assessments, Travel Plans, Delivery & Servicing Plans, Accessibility Analysis, Masterplanning & Regeneration, Traffic Engineering and Traffic Surveys for a number of London and South-East based clients.

With a strong understanding of the UK planning processes, particularly that of London and the South-East, Louise can help developments achieve planning consent through the production of quality Transport Assessments and Travel Plans. She can also provide transport advice and solutions for proposed new developments where required.

Junction Modelling and Design Capability

We can input geometrical data of T-Junctions and roundabouts, input visibility data and if required model a dedicated turn in the bay on the major road. We can also model the separated flow of traffic and blockage of traffic due to vehicle turning from the major road onto a minor road.

We use TRL software packages such as ARCADY, PICADY and OSCADY to produce our junction assessment reports. Our typical approach with some working screenshots is presented below from the TRL software packages.

We input traffic flow as O-D (Origin-Destination Data) in terms of vehicles per hour (veh/hr) or PCU (Passenger Car Units) per hour (PCU/hr). Percentage of Heavy Vehicle can also be modelled as part of the input of traffic flow.

We can also model under different demands depending on the situation and conditions of the model.

With those data, we are able to see the flow of traffic on each arm of the road and also calculate the length of time a vehicle is stationary and how many vehicles on average during the whole model are queuing up at each arm. Finally, it gives an indication of how good the lane usage and compare the flow to the capacity of the junction/arm. 

We can also simulate how vehicles move to different parts of the junction with the ‘Lane Simulation’ feature of the software. Part of the simulation allows us to add in the motion of the vehicles if there are dedicated lanes for any direction. The simulation also allows us to add any limits in between the arms to model the distance between the linked arms. 

Finally, the Junctions software allows us to link different multiple roundabouts, multiple T-Junctions or a mix of roundabouts and T-Junctions at the same time. The ‘Lane Simulation’ allows us to visualise the movement of vehicles and spot any bottlenecks and can allows us to add any road blocks such as construction vehicles or roadworks, or can also be used to model constrained flow of traffic on any side of each arm. +

Below is an example multi-link junction layout of 2 roundabouts and 2 T-Junctions. As can be seen below, the design of the junction link prevents the vehicles to flow smoothly and eventually the flow of the vehicles blocks the entire junction link. 


We would be pleased to hear from you and discuss your project requirement and provide a competitive proposal for the timely delivery of the project. Please call us on +44 (0) 333 006 2524 or email contact@aval-group.co.uk

Our Approach

We help our clients to secure planning permission by providing the most relevant and cost-effective project-specific solution for transport planning and access measures to satisfy the planning requirement. Whatever your transport statement requirements are, our experienced transport consultants can work with you and your project team to satisfy all planning requirements.

When an assessment is needed? 

Department for Transport (DfT) Guidance on Transport Statement and Assessment provides typical thresholds below which a formal assessment may not be needed, and above which the preparation of a formal assessment would be appropriate. If an assessment is required, there are two levels:

  • Transport Statement (TS): development that has relatively small
    transport implications.
  • Transport Assessment (TA): development that has significant
    transport implications

The key issues to be addressed during any pre-application consultations for a transport statement include the following:

  • Planning policy context of a development proposal;
  • Catchments or study area for the proposed development;
  • Assessment years – the year of opening and horizon year(s);
  • Assessment of public transport capacity, walking/cycling capacity and the road network capacity;
  • Person trip generation and trip distribution methodologies and/or assumptions;
  • Measures to promote sustainable travel; and
  • Mitigation measures (where applicable) – scope and implementation strategy.

Principals of a Transport Statement and Assessment

In preparing a transport assessment the following considerations will  be relevant:

  • Encouraging environmental sustainability
    • Reducing the need to travel, especially by car
    • Tackling the environmental impact of travel
    • The accessibility of the location
    • Other measures which may assist in influencing travel behaviour (ITB)
  • Managing the existing network
    • Making the best possible use of existing transport infrastructure
    • Managing access to the highway network
  • Mitigating residual impacts
    • Through demand management
    • Through improvements to the local public transport network, and walking and cycling facilities
    • Through minor physical improvements to existing roads
    • Through the provision of new or expanded roads
