Traffic Data Collection

TTRSA undertakes a wide range of traffic and transport related data collection for private and public sector organisations across Ireland and the UK. As an end user of data ourselves, we understand the needs of those using the data and the frustrations and wasted effort that can result from poor quality data collection.

Key Principles of Our Data Collection Service
  • Cost Effectiveness - We always try to be the most cost effective service provider. We are happy to discuss your data requirements so that your data is collected in the most appropriate and efficient way, and will process your data and structure our reports ensuring that they can be worked with immediately on receipt, saving you processing time and costs. When you need a survey, the sooner you commission the survey the cheaper it will be, because we can programme our workload to minimise costs.
  • Use of Experienced Staff - Our staff have been undertaking, analysing and managing all types of data collection for over 15 years. We don't employ inexperienced individuals to undertake one off surveys with minimal training.
  • Guaranteed Quality - As well as supplying data, we also use our own data for a wide range of traffic and transport related assessments and studies. We don't just say thay we provide accurate and reliable data, we guarantee the quality of data that we provide to clients.
  • Timely Delivery - We understand that data is often required in a hurry or needs to be collected at specific times. We always try to accomodate our clients needs. If we can't collect the data that you require, at the time that you require, we will tell you. We always provide a rapid turnaround of data, for example, Automatic Traffic Count (ATC) data is usually provided to our clients within 24 hours of the data being collected.

Main Types of Traffic and Transport Survey
  • Automatic Traffic Counts - TTRSA use Metrocount ATCs for short duration traffic counts, typically 24 hours, 48 hours, 7 days or 14 days. We have experience of deploying ATCs in all situations and conditions. Our ATCs record the direction, speed and type of each vehicle travelling over a pair of sensors, giving full flexibility for analysis and reporting. Whilst our clients usually require analysis to summarise the volume and type of vehicles traveling along a road, we also retain the 'raw' data so that we can undertake additional analysis of the data collected if necessary, without requiring an additional survey.
  • Speed Surveys - Speed surveys are often required by local authorities and other planning bodies where the visibility splays and sight distances set out in guidance such as the Design Manual for Roads and Bridges (DMRB) are either not possible or not desirable. Speed surveys are also useful to help designers determine the appropriate provision of infrastructure, such as whether to provide an on-road or off-road cycle track, and are essential for monitoring the effectiveness of the implementation of traffic calming and other safety schemes. TTRSA always work with best practice guidelines set out by relevant highway authorities and adopt the method for the speed survey which best meets your data/analysis needs.
  • Manual Traffic Counts -TTRSA undertake manual traffic counts, including Manual Classified Counts (MCC) for a wide variety of situations and all types of junction, using both enumerators and video based techniques. Our counts always include pedestrian, cyclist and equestrian movements at junctions. We are also working with technology providers to introduce fully automated video survey and analysis techniques which would, for example, allow a number of junctions within a town or city, or on a route, to be surveyed in parallel, whilst minimising the level of error between sites, reducing the time required by end users to check or manipulate data between sites.
  • Pedestrian Surveys - TTRSA undertake a range of pedestrian surveys, which can be customised to your requirements, including: directional flows and footfall on routes or links; study and analysis of crossing movements using both manual and video techniques; and, intercept surveys to establish the origin, destinations and purpose of pedestrian trips to establish patterns of use of footway networks. We are also happy to undertake intercept surveys of cyclists and equestrians, and conduct more in-depth behavioural surveys.
  • Passenger Surveys - TTRSA staff have undertaken on-board and interchange based passenger surveys on buses, metros, trains, at stations and at airports. Whilst passenger surveys typcially focus on operators gaining a better understanding of passengers views on the provision of, and quality of, services, a wide range of highly focused business related information can be gathered.
  • Car Parking Surveys - TTRSA undertake a range of on-street and off-street parking surveys, tailored to individual clients needs, including: parking beat surveys; commercial loading and servicing surveys; parking behaviour surveys; and, video based surveys of parking areas with defined entrance and exit points. Typical analysis from such surveys include: parking location, parking duration, parking activity by particulur user groups such as residents; parking accumulation and availability; and, compliance with prevailing regulations. We always work with clients to establish the optimum data collection framework and can also advise on a wide range of parking management solutions including the introduction of, and changes to, parking charges and restrictions.
  • Journey Time Surveys - TTRSA undertake journey time surveys using the latest GPS tracking based technology allowing a full understanding of the freeflow speeds at any given point on predefined routes, in addition to elasped journey times between defined points. TTRSA can also apply this technology to 'probe-vehicles' such as buses to allow operators without permanent tracking technology to better understand the delays being experienced by their vehicles without the need for driver reporting. Journey time survey reporting can be fully customised to user requirements including presentation on base mapping and suitable for traffic model validation.
