Lane Markings

Pavement Markings are an important roadway feature which contribute to safety by guiding both drivers and pedestrians. However, over time, the condition of pavement markings deteriorates due to environmental conditions and mechanical wear from traffic as well as snowplows in cold weather climates.

Pavement markings also play an important role in Pavement Management as they are typically used to officially denote the boundaries of road lanes and thus become the limits within which pavement distress are to be recorded and reported.

PavemetricsTM Laser Crack Measurement System (LCMSTM-2) helps to automate the management of pavement markings and their use as distress rating delimiters. The pavement marking module detects and returns the position of pavement stripes, directional arrows and messages. These data are also used as an input into other LCMS algorithms such as the rutting model and other models that report according to road zone (e.g., the AASHTO zones).

Reporting for marking includes position, type, dimensions and condition (based on laser light return) in XML format in addition to a variety of images showing detected markings highlighted.
