TRICS® has over the years undertaken or commissioned a variety of research projects, the reports of which all of which are freely available to download here. TRICS® member organisations can also download these reports via the TRICS® Library module (once logged in and running the TRICS® system).
We always welcome ideas and suggestions from both TRICS® users and non-users for potential future research initiatives, so anyone with ideas for potential research should contact the TRICS® team.
This report has emerged from the sponsorship of a PhD course of study by the TRICS® Consortium in collaboration with the Economic and Social Research Council. The work sought to answer a number of questions and particularly, establish a scientifically grounded response to two key issues (i) can the data held in TRICS® be used for 'sound' econometric modelling and (ii) using appropriate econometric methods, is land zone placement (as defined in accordance with Planning Policy Guidance definitions) a genuinely important determinant of trip generation behaviour. The three land use categories studied in this project were office developments, food superstores and residential developments.
This research study is focused on multi-use sites which do not necessarily meet the definition of "mixed use". The term "mixed use" is currently a loosely defined policy objective and is thus difficult to evaluate using existing quantitative data. The research into multi-use will help inform the debate regarding the benefits of so-called mixed-use development. It will also highlight important factors that development control practitioners will need to consider when evaluating development proposals. The research is based on extensive analysis using data from the TRICS® database.
This research includes the collection of background information, including specifically commissioned multi-modal TRICS® surveys, to understand how the health sector and establishments within it operate and are influenced. TRICS® information is used to consider trip making and modal share. The influence and effect of Travel Plans is also considered.
In this report a concept of Back Validation has been adopted to investigate a process that can look back in time and verify the continued applicability, or not, of historic database sites. The objective of this research is to provide supplementary input and guidance as part of the "toolkit" for the user of the system. It aims to provide a positive steer to users when they consider how appropriate it is to use historic data.
This report is a review of the effectiveness of Travel Plans and their characteristics, an identification of the information needed to quantify the effect that Travel Plans will have on mode of travel, and researches current TRICS® data and the future role that TRICS® can have in incorporating Travel Plan effects. The approach adopted for this study has been to review existing research, and based on this review, to make recommendations for a possible way forward for incorporating the effect of Travel Plans into TRICS®. This research differs from other Travel Plan research projects in that it has sought to identify a common assessment method for understanding Travel Plan effectiveness.
The objective of this report is to assist TRICS® practitioners in identifying typical profiles of vehicle trip making throughout the course of a year for different types of land use. The research illustrates how traffic activity varies for different land uses by time of day, day of week, and month of year. During 2000, a total of 16 sites were identified for possible consideration, for which subsequently a full analysis was undertaken in 2001 for 8 sites. The eight sites cover five of the 16 main land use categories used as parameters within the TRICS® database. These are Retail (3 sites), Employment (1 site), Health (1 site), Residential (2 sites), and Golf (1) site.
This report examines the variation in levels of parking provision within new developments, for example by public transport accessibility or location, and relevance to travel characteristics by mode. The broad objectives of the research was to explore the relationship between parking provision, accessibility and mode choice for new developments; examine how the level of parking influences and relates to the mode choice; provide advice on parking standards for new developments; and determine appropriate definitions of modal accessibility, appropriate for use in TRICS®.
This report explores the circumstances in which trip rates vary, using various data sources (including retail sales information as well as the TRICS® database), and develops guidance on good practice in trip rate selection and use. The report also contains an examination of the relationship between parking supply and peak parking demand, which has important implications for the use of trip rates in estimating parking provision.
This report contains analysis of travel surveys undertaken at two foodstores in Staffordshire and provides information on travel by different modes, customer characteristics, use of the car parks, trip lengths and the level of primary trips. The results of the surveys are also compared with those from the earlier TRICS® Safeway research (reports 95/3 and 95/4).
This report analyses the results of questionnaire-based surveys and pedestrian/vehicle counts undertaken at four non-food retail parks in Dorset, Kent, Lancashire and Surrey. Each of the parks was surveyed on a Friday, Saturday and Sunday in 1996 and the results provide a valuable insight into the transport and shopping characteristics of this land use.
This report contains detailed calculated results to support the summary tables presented in 95/3.
This report summarises the results of surveys undertaken at 9 food superstores in November 1994. 1,000 interviews were undertaken with customers at each store and this was supplemented by traffic counts. The report illustrates the effect of store location on modal choice, parking requirements, travel length and relationships with adjacent land uses.
This report draws together the work that has been undertaken over the last 10 years on defining and quantifying "diverted and pass by traffic". An extensive bibliography is included.
This report provides an addendum to 93/1 by looking at an additional 14 office sites located on the fringe of London and in other areas where on-site parking was heavily constrained. The results confirm the conclusions from the previous report which outlines the importance of the management of on-site parking space.
This report analyses the basic assumption in the preparation of Traffic Impact Assessments that the aggregate level of traffic generated by a new retail development will be finite and static from the first year of opening until the store eventually closes or changes its trading position in some way. Average trip rate changes are calculated for all available data on the TRICS® database. This is backed by significant testing. The additional customer flows are analysed, so illustrating the effects of local competitive changes.
The report analyses the result of surveys at 60 offices located throughout the Southeast Planners Region to determine the relationship between parking, public transport and modal choice. The study concentrated on the journey to work trip.
The report concludes on the effect of the seven day trading patterns of seven food superstore sites throughout the Christmas period. The results are compared with data held for stores trading pre 1991. The sites included are Asda, Burgh Heath; Asda, Fareham; Sainsburys, Burpham; Sainsburys, Chichester; Sainsburys, Poole; Tesco, Bognor Regis; and Tesco, Hookwood.
This report compares parking demand ratios for land uses on the TRICS® system. The land uses include food superstores, DIY superstores, retail parks, offices, business parks and general industrial. The report studies in detail traffic flow data from a total of 223 sites. The results produce a statistical analysis of each land use classification and give a maximum parking demand ratio for each individual site.
The report sets out the traffic generation from three marinas (Agememnon Boat Yard, Bucklers Hard; Lymington Yacht Haven; Mercury Yacht Harbour, Hamble). Automatic traffic counters were established for 4 weeks throughout August 1988. Also, detailed parking accumulations were surveyed on one Saturday. The report contains details of the three sites and details of weather and tides (60 pp).
Based on surveys undertaken in 1984 at 60n industrial sites in England (21), Scotland (14), Wales (13) and Northern Ireland (12). The report establishes regression relationships for trip generation. Trips are subdivided by purpose (i.e. commuting, business and deliveries). The work was undertaken for the Scottish Development Agency, the Welsh Development Agency, the Northern Ireland Development Agency and English Industrial Estates. The report comes in two parts, firstly the analysis of data and secondly the establishment of a formal estimate procedure (130 pp).
The report reviews the parking standards for most land uses. Data from other authorities was compiled as a comparison. Maximum parking accumulation for different land uses was extracted from the TRICS® database and some 60 "spot" surveys were undertaken to determine maximum parking usage. Detailed discussions with other highway authorities to review the problems of parking standards are reported. The report contains recommendations for revised standards (180 pp).
A detailed assessment of traffic generation from 2 superstores, 2 DIY stores, 2 business parks and 2 offices. Data was collected by counts and interviews. Additional data exists in the report on modal split to offices and catchment areas for each development. The report contains full details of traffic counts and parking accumulations at each site in half hour periods (180 pp).
The report contains detailed traffic count data for 12 offices and "High Tech" sites surveyed in 1988. The data was collected by a variety of survey techniques including roadside interviews, foyer interviews and employee interviews. The report contains traffic flows in and out of each site with associated parking accumulation. Additional data exists for some sites on modal choice. Trip length distributions (employment catchment) are available for all sites. The report covers 4 offices in Central Uxbridge, 2 "rural" office complexes, 2 offices in local centres, 2 industrial estates (traditional) and 2 high tech sites. One of the high tech sites was Stockley Park with 100%,000 sq. ft. of development (150 pp).
TRICS® Consortium Limited regularly undertakes technical analyses and produces technical reports and guidance documents that we consider to be very useful for our member organisations. A selection of more recent and key documents can all be freely downloaded from here.
TRICS Consortium Limited is pleased to announce the publication of a new Technical Note, “A Comparison of Vehicular Trip Rate Variation by TRICS Regions and Location Types”, which is now freely available to download by everyone. This report presents the findings of research recently undertaken by the TRICS team into vehicular trip rate variation by region, when compared to an identical exercise by TRICS location type. It examines vehicular trip rate variance by examining three of the largest and most often used land use categories in the TRICS database, these being 01/A (Food Superstores), 02/A (Offices), and 03/A (Houses Privately Owned). Our existing TRICS Good Practice guidance has always advised that our users should refrain from deselecting sites by geographical region as a default method, and instead should consider the TRICS location type along with a number of other local factors that may influence vehicular trip rates. We have now undertaken a set of technical analyses using the TRICS database to provide further clarity on this subject to our Good Practice Guide, which is being updated in 2020. A presentation on the report and its findings will be given at the 2019 TRICS Training & Development Forum in Oxford this November.
TRICS Consortium Limited (TRICS) is responding to the fact that the world is experiencing significant change in relation to social, technological, economic and environmental drivers which in turn is creating new dynamics in travel behaviour and challenges for transport planning. In the face of deep uncertainty, the “predict and provide” paradigm that has framed transport planning processes is to give way to “decide and provide” paradigm – decide on the preferred future and provide the means to work towards that which can accommodate uncertainty.
It is fundamental that TRICS, as a spatial planning tool, provides direction to support the “decide and provide” approach and managing uncertainty in forecasting and trip generation analysis.
TRICS is therefore seeking to gather together the evidence of change and consider in what ways the use of TRICS may be developed to consider the impact of changes in travel behaviour.
BasfordPowers (BP) in conjunction with ITS Leeds (Professor Greg Marsden) and UWE (Professor Glenn Lyons) has been commissioned to produce a TRICS Guidance Note concerning Change in Travel Behaviour.
It is proposed that this Guidance Note informs TRICS users of the changes in travel behaviour and discusses the implications of travel trends for TRICS users. Further research maybe required to understand the implications of the evidence concerning trip rate reductions which have been cited in the All Change Commission on Travel Demand report on the use of TRICS data and analysis. Future traffic forecasts included in the Department for Transport Road Traffic Forecasts 18 will also have implications for the use of TRICS which also needs to be understood.
Section 5 of this report contains Ten Key Questions for TRICS Users. We have created an on-line survey for our users to participate in, where you can provide your views if you would like to assist in the further development of a “Decide and Provide” approach to transport planning. The survey asks users to answer these ten questions, and there is also the opportunity to provide your additional comments at the end.
As always, TRICS Consortium Limited greatly appreciates the views of its user.
TRICS Consortium Limited are pleased to announce the publication and free availability of our technical report covering multi-modal and internalisation surveys undertaken at the Cambourne Village development in June 2018.
We believe this study is the first of its type. We surveyed the whole Cambourne Village site incorporating the usual multi-modal TRICS methodology, plus we also surveyed a number of separate internal non-residential developments within the overall site, looking at splits between internal and external trips, plus the types of journey that were being undertaken. Of course, the study only covers one particular large new settlement on one day (all surveys were undertaken simultaneously), and our results do not reflect any other similar new settlement, but the question of internalisation within such developments has been something that has been raised for a number of years, so we are pleased that we have been able to start looking into this in more detail. We see this as just the beginning, and we look forward to receiving feedback from anyone interested in this subject.
We are also pleased to announce that an analysis portal that TRICS users can use to interrogate the survey results is also available within the Members Area of this website (just log in with user details and it is available there). At the end of the technical report there is some guidance on how to use this facility, which allows our users to look at the individual non-residential developments within Cambourne Village and undertake a variety of analyses based on survey time periods, the types of journeys being made, and splits between journeys to and from these developments made by people from within Cambourne Village and those external to it.
As always, the TRICS team are on hand to answer any queries you may have about this study.
