Kav Medida performs a variety of surveys and detailed planning, interior measurements, and 3D modeling as part of a project to establish a mass transit system in the Gush Dan metropolis. This is a field project that is considered one of the largest and most complex since the establishment of the state.

There will be a system for mass transportation in the Tel Aviv metropolis, which is intended to be the main means of public transportation throughout Gush Dan. Also, four light rail lines and three multi-capacity bus lines (BRT) will be implemented.

In August 2015, the construction of the first line of the light rail lines, the Red Line, began, which will pass through five cities: Petah Tikva, Bnei Brak, Ramat Gan, Tel-Aviv-Jaffa, and Bat Yam.

In the area of the city of Tel-Aviv-Jaffa, along Begin Road, at the end of Railway Street and towards the station complex, the train will travel on an underground route, and along Jerusalem Boulevard in Jaffa it will travel on an above-ground route. The train will operate on electric propulsion, thus reducing noise and air pollution and improving the quality of life for city residents. The operation of the red line will significantly improve the availability of public transportation to residents along its route.
