4K Video Surveys- Streamline Your Road Network Management

Overview

Roadshow is our License-Free proprietary software for presenting Video and GPR data to our clients. It is currently available in two formats depending on requirements:

Offline

The offline version of Roadshow is a standalone piece of software that can be used locally on your computer. The offline Roadshow Suite has a whole range of tools and customisation options for querying your data.

This is usually delivered to the client via a download link from our secure servers or removeable media.

Online

Our Roadshow Software is now fully available online. This makes all of your data available at incredible convenience though our secure web portal. All of your Video and GPR data in one place so repeat surveys can easily be toggled between to monitor and review changes to your assets and defects. Our high-quality mapping and GPS positional accuracy can display all asset and defect types geospatially. These can then be monitored, edited or deleted by the user. You are also able to create new items,  as to either establish or fill in the gaps of your existing inventory.

Our 4K Video surveys are collected at true traffic speed, meaning there is no need for expensive and time-consuming traffic management. With a totally modular system we really can tailor the results you will receive to match the objectives of the survey. For example, if you are assessing Gullys, we can point a camera directly at them. Each view is a true 3840 x 2160 pixels giving an 8.3MP image.

The data is collected in 4K resolution with high accuracy GPS and Wheel Encoder inputs. This allows us to present your data with extremely high accuracy. See above for more information on how your data can be presented in Roadshow. See below an example of 4K (left) vs regular HD (right).

On-Carriageway

You can use our Roadshow software and mapping to geospatially position a wide variety of on-carriageway assets and defects. These include:

• Longitudinal and Transverse Lines
• Road Markings
• Road Studs
• Hatchings, Chevrons, Tiger Tails and Box Junctions             
• Defects on the running lanes     

Off-Carriageway

Similar to on-carriageway, you can use the Roadshow software and mapping to geospatially map a wide variety of off carriageway assets and defects also. With our additional camera views clearly pointing off-carriageway you can assess all that is required in 4K resolution.  Some off-carriageway assets/defects include:

• Traffic Signs
• Vehicle Restraint Systems (VRS)
• Lighting Columns
• Traffic Lights
• Comms Cabinets
• Vegetation Management
• …

The list is endless. Please enquire for more information on how we can meet your survey needs.

AI Defect Detection

We have a fully developed system using our 4K Video to locate and analyse certain carriageway defects. This is achieved by using our high-quality video and computer learning software. We have fed 1000's of manually collected defects into the software since its inception to allow it to automatically, and more importantly accurately identify defects by itself. 

Visual condition Survey (VCS)

Using our 4K video we can complete traditional VCS surveys that are fully compliant with “CS229 – Data for pavement assessment”. The output for these surveys is a PDF report with photographs, defects in csv format including OSGR’s and Strip Plans.

PAS2161:2024  

The PAS is designed to standardise the methodology for the data capture, processing and reporting of RCM data. This ensures uniformity across different networks. By defining clear condition categories for carriageway networks, the PAS aims to promote a consistent understanding and assessment of road health. This will then feed directing into the DfT Reporting requirements.

We have been producing routine Visual Condition Surveys for the UK transport sector since 1995. Initially using traditional on-site methods before switching to HD Video and now using multi-View 4K Ultra-High Resolution. Using a combination of highly experienced engineers and Artificial Intelligence, assessing your network has never been easier.

CVI / DVI Surveys

Coarse Visual Inspection (CVI) are used to record the presence of defective areas of carriageway, footway and kerbing. These are conducted from a vehicle and enable the recording of such defects as cracking, crazing and rutting. CVI surveys are performed to national standards. 

Detailed Visual Inspection (DVI) surveys enable the collection of much more detail relevant to defects on roads and pavements. Such defects as cracking, subsidence, chip loss and the like are all recorded, together with their associated dimensions.

The primary use of such surveys is to assess the condition of the busier pavements on your network. 

Both types of survey can assist you with the appointment of budgets for future maintenance works.

Our unique, 4K imagery gives an unparallel visual track record of the road surface condition for both CVI and DVI applications from the safety and reliability of a desktop study.

High Friction Surfacing (HFS)

Using our 4K Vertical imagery we have developed an AI system which analyses each frame to provide an accurate High Friction Surfacing (HFS) inventory and subsequent analysis. The model analyses the full carriageway width and determines the quantity of material that is lost and thus deteriorated. This is then reported in either HAPMS (P-AMS) Chainage or geospatially.

Where footways cannot be seen from the main carriageway, we use multiple 4K cameras mounted on a tricycle to ensure full coverage of your footway network.  The resultant videos can be viewed in our Roadshow software suites which provide the user a 360-degree view from the current position shown on a map. From this we are able to locate and record multiple defect and asset types.

In the case of the Safer Cycling Video Survey (SCVS) the cameras are mounted on a tricycle around head height. Both on-carriageway and off-carriageway cycleways can be surveyed.  The resultant videos can be viewed in our Roadshow software suites which provide the user a 360-degree view from the current position shown on a map. The uses are plentiful and in the case of the SCVS it gives the “cyclist” view and danger spots for cyclists can be identified.

By using a 4K Digital Video System calibrated to the human eye instead of using retroreflectivity meters, actual sign performance can be measured in terms of the true sign interaction with the driver where other factors, such as sign orientation and obstructions, can be taken into consideration.

As always with video systems, they allow a greater degree of quality assurance rather than relying on discrete measures, which in this case are taken from retroreflectivity meters.

The sign images are stored and archived. With more and more traffic on the UK’s roads and Hardshoulder running it is no longer possible to carry out the traditional methods due to safety concerns.

​Not only is Traffic Speed Retroreflectivity cost effective it is inherently safe and produces consistent results to allow comparisons year on year.

Using 4K imagery captured at night combined with specifically calibrated lighting we are able to obtain the retroreflectivity of line markings. The value of retroreflectivity determines the visibility of the line markings at night. Our research programme has produced algorithms to convert grey-scale intensity to Retroreflectivity Luminance (mcd.m-2.lx-1) 

​The system operates at traffic speed and the lines are illuminated by a high intensity LED source. The receiving CCDs are calibrated to reproduce comparable grey-scale outputs. The system collects left and right edge line marking retroreflectivity simultaneously from the digital video. Analysis is automated and outputs are a measurement of retroreflectivity averaged over 2 meters in Geo-Referenced form.

Line These results can be statistically analysed along with street lighting information to produce green, amber and red traffic light style output to highlight the areas requiring improvement. Outputs are in CSV, Shapefiles or as per the client’s specific requirements.

Using the same methodology as we use to detect line marking retroreflectivity we are also able to automatically locate road studs and measure their Retroreflectivity Luminance (mcd.m-2.lx-1).

The system operates at traffic speed and the studs are illuminated by a specifically calibrated LED source. The receiving CCD's are then calibrated to reproduce comparable grey-scale outputs. The grey-scale values are converted to retroreflectivity luminance using Impulse Geophysics proprietary algorithms. Along with the automatic detection of the Roadstuds colour we can then determine whether the stud is working and reflecting as intended. 

We understand that your data is sensitive and could be harmful should it fall into the wrong hands. This is why we offer full redaction of your video data. This involved the blurring of all Personally Identifiable Information (PII) in the form of Registration Plates and Faces. We can also redact any information if required. For example, Road Traffic Incidents. *This service must be requested at the time of purchase as the standard video delivery is un-redacted.
