As a manufacturer of road marking retroreflectivity measurement systems we are regularly approached by government road agencies to provide road marking retroreflectivity surveys on specific areas of the road network. Providing we have no customer providing survey services in that area, we are happy to quote for and undertake this work. Where we have an existing customer operating in that area, we will pass the enquiry to them to deal with.
Pavement Marking Retroreflectivity Surveys
Our road marking retroreflectivity condition surveys include data gathered on all pavement markings to the left and right of the survey vehicle and lane travelled, including critical center lane markings warnings and symbols and also the presence or absence of road markers/reflectors to the left and right of the road lane travelled.
Our QuickView-Pro survey visualisation software provides full visualisation of the survey results, with comprehensive mapping and colour coding of results to simplify pinpointing areas that fail or are reaching minimum standards for retroreflectivity. It is even possible to view markings that have failed using the recorded GPS tagged video footage results, saving the cost and inconvenience of sending a crew out to inspect the road marking failures. The start & end coordinates of failed areas can be processed & results sent to the necessary maintenance departments.
This assists with identifying & predicting where maintenance of markings is necessary to ensure compliance to MUTCD minimum maintenance standards.
Pavement Marking Survey Details Collected:
- Night-time visibility- Retroreflectivity of all road pavement markings
- Retroreflectivity Right & Left Lane lines and centre lane markings i.e. symbols /arrows etc
- The absence and presence of RPMs / Reflectors / Markers
- Each longitudinal line width
- Day contrast ratio (Weber) when surveyed in daylight
- Indicates if single or double lines
- Indicates if skip or continuous lines & double line combinations.
- Indicates marking colour – white / yellow (Orange in development)
- Individual Retroreflectivity for each line in double lines.
- Measurements all GPS tagged with map & video images
- Road name & number
- Temperature & humidity
Our team will assess your survey requirements and determine the optimum routing to gather all the data you require as cost effectively as possible. The results we provide will enable you to plan road maintenance. In addition, we have a strong track record in collaborating with Road Agencies, Striping Contractors and Toll Operators on Research & Development projects to improve the assessment and quality of pavement markings and assets.
This pavement marking retroreflectivity surveys service is particularly useful for government agencies, Cities, Districts, Counties & Councils with smaller road networks or insufficient budget, where it would be difficult to justify the cost of purchasing survey equipment to perform surveys on the road network annually.
