Traffic Surveys
Traffinomics provide an extensive range of traffic data collection methodologies, from the basics of one off traffic surveys (counting and classifying vehicles and/or speed measurement) up to the large scale origin/destination surveys, medium to long term monitoring and town centre studies.
We are typically engaged by land owners looking for a site line issues to be resolved (Further Information Request), up to major urban traffic studies for County/City Councils and other public bodies, Civil Engineering Establishments, and Retail Organisations etc.
Typical Survey Menu (but not limited to)
- Junction Turning Counts (CCTV)
- Automatic Traffic Counts (ATC)
- Bi-Directional Link Counts (CCTV/ATC)
- Speed Measurement (ATC/Manual)
- Pedestrian Counts (CCTV/Bluetooth)
- Queue Length Observations (CCTV/Manual)
- Journey Time Surveys (Van Cam CCTV/Manual/Bluetooth/ANPR)
- Origin/Destination Surveys (Bluetooth/ANPR)
- Junction Geometry/Flare Length Measurements (Manual)
Types of traffic surveys
Manual Classified Junction Turning Counts
Manual classified junction turning counts are our core business. Our entire junction turning count data collection is undertaken using remote roadside secure CCTV systems. Imagery data can be collected for up to ten days depending on the scale of the project.
Origin Destination Surveys (O&D Surveys)
Origin‐destination (O&D) surveys provide a detailed data of trip patterns and travel choices of area. O&D surveys collect valuable data on households, individuals and trips. The data provides understanding with regards to:
- Travel patterns and characteristics
- Travel demand model development
- Forecasting and planning for area‐wide transportation needs and services
- Implementation of transportation policies
Automatic Traffic Counts (ATC’s)
We undertake automatic traffic counts (ATC’s) utilising “MetroCount” counting apparatus for typically longer term (weekly) bi-directional traffic and speed monitoring. From major traffic monitoring projects, to “further information” requirements. for a private dwelling site line issue.
ATC’s are a very cost-effective way of collecting typically seven days worth of data. Bi-directional classified traffic volumes and 85th percentile speed surveys are a common use for this type of equipment.
Queue Length Surveys
Queue length surveys can require one of several techniques to be applied and thus produce varying data outcomes. The objective of the survey dictates what form of data collection is most appropriate.
The most typical approach is the simple observation of traffic. The number of vehicles in a queue or the physical extent of the queue just prior to signal changes is recorded. Data is collected per lane and per approach to the specified feature/junction.
Queue length survey data is generally collected manually using roadside observers. One or more staff record traffic observations per junction depending upon how many approaches are to be surveyed. Records may include the extent of the queue on every cycle, or on a maximum queue observed in a specified time period – 5 or 15 minutes.
Journey Time Surveys
We undertake the journey time surveys using ‘Van Cam’ units installed in our survey vehicles. This allows for the collection of timing data at pre-determined locations plus information relating to queue times at each junction or feature.
On-board cameras and recording devices allow the client to not only see time / date stamped HH:MM:SS node to node journeys, but also traffic conditions during the survey data collection – weather conditions, accidents, road works, queuing, congestion and any other unusual events.
Our traffic surveyors using digital voice recordings record additional information.
