NDRC Intelligent Traffic Systems

The ITS2020 Project aims to expand the ITS infrastructure, step up the performance of key road networks through improved mobility, safety, traffic control operations, and provision of traveler information for all road users in Dubai. The project involves an expansion of traffic CCTV monitoring, radar detection, and full matrix dynamic message sign sub-systems in addition to a complete Ethernet-based Fiber Optic communication network and an Integrated Advanced Traffic Management System (ATMS). The installation was carried out using the directional drilling technique with launching and receiving shafts at both ends. 

As the project required the construction of NDRC 5.2 m below the Red line metro tracks (on ground towards the end of line), instrumentation was planned for safety monitoring of structures, as well as for the risk management of construction works, even though the shaft excavation was only upto 2.5 m depth below the ground level. The tunneling length was 43 m.

Encardio-rite’s sister concern Encardio-rite Geosystems LLC in UAE was instructed by the Road and Transport Authority (RTA-Owner of Metro structure) and China State Construction Engineering Corporation Ltd. to provide instrumentation and monitoring program during NDRC to assess the impact on adjacent structures including the Dubai Red Line metro pier as per M/s RTA code of practice.
