The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section.The PCI is widely used in transportation civil engineering [1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

The procedure to calculate the ACN is as such: Design a theoretical pavement according to a defined criterion: For flexible pavements, design the pavement for 10,000 load applications of the aircraft according to the CBR design procedure combined with Boussinesq's solution for deflection in the elastic half-space
A rotating cone tactile device is a haptic device used at traffic light controlled pedestrian crossings in the United Kingdom. It is used as a tactile signal for blind pedestrians to indicate that it is safe to cross the road. [1] The idea for the devices originated at the University of Nottingham in the 1980s. [2]
