The system that challenges and validates assumptions about the transport impacts of new developments

Latest News

A number of online presentations have been put together following the publication of the Decide and Provide report released earlier this year, and we thought it would be a good idea to put a recording on the website to allow all TRICS Members to see these. The Covid-19 restrictions over the past 18 months have made it difficult to undertake presentations in person, so it is hoped that these short videos will assist until we can host a fully live event.

2021 has seen a high demand for commissioned TRICS SAM surveys. It has been good to get this process back up and running following the suspension of surveys in 2020, with many surveys having taken place, and numerous requests for surveys in the autumn window continuing to come through to the TRICS team.

Please note that the deadline for new TRICS SAM survey commissions for the Autumn 2021 window is noon on Friday 24th September 2021. After this date, any new surveys will need to be added to the Spring 2022 window which commences next March. The TRICS team have been working hard to accommodate client requests for commissioned surveys in what continues to be a very busy year, but we have to allow reasonable lead time for our TRICS-approved data collection contractors, especially for more complex and resource-intensive survey sites.

All SAM survey clients should also be aware that any new surveys added to our current list prior to the 24th of September deadline will need to move swiftly through all stages, including the signing of survey agreements and the authorisation of surveys (including the raising of purchase orders) once our quotes have been provided, to ensure that the surveys can take place in the remaining timeframe of the Autumn window. Any significant delays through the process will mean that it is likely that surveys will need to be moved to the Spring 2022 window or removed from our records.

We look forward to continuing to work with all of our TRICS SAM survey clients through this year and into the next.

Having had internal discussions, TRICS Consortium Limited has taken the decision to cancel the 2021 TRICS User Meeting, which was due to be held in Central London on 28th September.

We did have the option of holding the event with social distancing measures and reduced capacity restricting it, and this was followed by an offer of the meeting being a “pilot event” without these restrictions in place, but having discussed this all in more detail we made the decision to fully cancel the event, as we deemed conditions to be too risky given the rapidly increasing coronavirus cases in the UK and the uncertainty this would bring. Add to this the fact that we were getting closer to the event’s date (just over two months away at the time of us making this decision), and the fact that a significant number of people may not have been comfortable about travelling in and out of Central London at peaks times in such conditions, and in the end we felt it was a practical and sensible decision to make. It should also be noted that some commentators have been talking of the possibility of the current increase in coronavirus cases going on until possibly September. We also feel that any online version of our events just wouldn’t work the same way, as we get so much from the interactions between attendees in addition to providing the presentations, so we would rather wait a bit longer and then get back to our events the way they should be when the time is right.

Moving forwards, we fully intend to resume our annual Spring and Autumn events, but we have decided that we will only proceed with them once everything has come under control in the UK. We shall only recommence planning our events once we are as sure as we can be that we would not need to postpone them again, so for the time being we shall go into 2022 and assess things in the first instance at that point, with a view to one or both events taking place next year, without being committed to any timescales as things currently stand. We will of course continue to update everyone as to how things progress.

We are all disappointed that we have had to cancel our event, but we are looking forward to better times and at last resuming our regular gatherings of the TRICS Community that provide so much great value and feedback.

TRICS Consortium Limited has decided to introduce a new TRICS count type of “scooters” into all surveys undertaken from 2022 onwards.

This new count type will not differentiate between motorised and non-motorised scooters, so will apply to all types (including the smaller ones that children use). In effect, scooters will be treated the same way as we deal with pedal cycles, in that they will be recorded as an independent count type for both Level 1 (traffic) and Level 2 (multi-modal) TRICS surveys. This will mean that the TRICS database system will also be adapted so that trip rate calculations can be undertaken for this new count type just as they currently are for the pedal cycles count (which of course also does not differentiate between pushbikes and electric bikes). Therefore, the introduction of scooters in TRICS surveys should be relatively straightforward.

It is very clear from observation that these scooters are growing rapidly in number and are here to stay in one form or another. As they evolve over time we may be in a position to consider splitting the new count into potential sub-types, but in the first instance we will just cover every type of scooter (excluding the motorbike type which of course continue to be recorded as motorbikes) under one umbrella scooters count.

The December 2021 release of TRICS version 7.8.4 will include all the information that our users will need, with the systems architecture updated along with our Good Practice Guide and Multi-Modal Methodology document. The TRICS Help system will also be updated accordingly with the new count type definition etc.

We welcome your feedback and further suggestions on this topic, as we are opening up an unofficial consultation following this announcement over the next few months before we undertake the necessary systems work. As always, should you have any questions these are warmly welcomed.

TRICS Consortium Limited are pleased to inform all organisations involved in the commissioning and undertaking of TRICS surveys, as well as all TRICS users, that TRICS site visits and surveys will resume from 12th April 2021.

This is subject to the partial lifting of lockdown restrictions in England (the opening of non-essential shops) taking place on that date, which reduces the level of restrictions down to beneath our threshold for the suspension of TRICS survey programmes.

Although we continue to monitor the situation closely and our plan is subject to change whenever necessary, our current plan is to raise new agreements for the SAM surveys we currently have on our books (plus any new surveys that are added in the interim period) on 1st April 2021. The agreements would then be forwarded to our SAM clients for signing, with site visits then arranged on a first come first served basis (meaning the receipt of signed copies of the agreements being received).

This gives us a good opportunity to fit some SAM surveys into the Spring survey window that runs until the end of June. As per our February statement, I cannot guarantee that any survey will be undertaken during the Spring window. It is important to note that it will be essential to receive a quick turnaround in terms of the signing of survey agreements and the authorisation to proceed with surveys once quotes have been supplied, with any significant delays meaning that surveys would need to be moved into the Autumn window.

Our plan also allows for the first surveys in our regular regional data collection programme commencing in the second half of April, and work is underway to achieve this. With regards to surveys outside of England we will make comparative assessments on a regional basis moving forwards. We remain on track to deliver a full regional programme of traffic and multi-modal surveys in 2021, and the team are ready to get to work and deliver this for our users.

Once again, we would like to thank everyone in the TRICS Community for their support and understanding through these turbulent times. Our goal is to provide you with great quality data covering a wide range of regions and development types throughout 2021, and we certainly look forward to achieving this.

TRICS Consortium Limited are pleased to announce the publication of our Guidance Note on the Practical Implementation of the Decide and Provide Approach for future development planning, which is freely downloadable from our website at

Decide and ProvideThis document is the result of a broad and thorough collaborative effort from different planning perspectives, including members of the TRICS team, local highway authorities, the academic profession, the Department of Transport and independent consultants. Now, more than ever, we need to reassess approaches to transport and development planning, and the collaboration behind this project has allowed us to present the idea of the new Decide and Provide approach, whilst also providing strong evidence, using the wealth of historic survey data within TRICS, of trip generation trends over time, which themselves illustrate that the principles behind this new approach are grounded in hard data. It has become clear from our analyses that there has been a reduction in vehicular trip generation over time for key land uses, and that we should adapt the TRICS system and introduce new elements into its analytical features to allow a new type of trend interrogation of the database, whilst keeping TRICS a vital and integral part of assessing future trip generation estimates.

For over 30 years TRICS has been instrumental in our planning processes, and as an organisation we are very pleased to be playing our own important role, along with our collaborative partners, in addressing one of the most important questions in transport and development planning today. The work that has been undertaken has shown that TRICS will continue to be a fundamental element of the new Decide and Provide approach. We have always been an organisation that can adapt and evolve over time and participate in addressing important issues with the experience of our team in trip generation analysis, data collection programmes, system development and research, and forward thinking. We are ready and willing to make the necessary changes and to show our users how TRICS could be used alongside the new Decide and Provide approach, providing essential guidance which has started with the publication of this document. We need to make it clear that publication of this document should be regarded as the first stage of this journey. There is plenty more work to do, and we look forward to more of our users and other organisations coming on board to join our growing collaboration towards a new future for development planning that aims to face the industry’s (and the nation’s) challenges head on with positive solutions.

There will be a great need for a new environmental approach as we emerge from the pandemic, especially when it comes to the decarbonisation of transport. We live in an uncertain world, and the question of uncertainty can clearly be extended to transportation and the future of development planning. The new Decide and Provide approach embraces that uncertainty, and offers a clear and distinct method for how the practices of our industry should and can change, and TRICS intends to be leading the way in terms of providing practical and solid survey data analysis solutions. Through an extended period of discussion, data analysis and application of ideas that are firmly rooted in the challenges that lay ahead, we can all implement a new forward-thinking approach to development planning and Transport Assessments fit for the 21st Century.

We look forward to receiving your much welcomed feedback and to working with you all in making these changes happen.
