We have developed country-specific procedures for the establishment of criteria for investment in feeder and rural road rehabilitation and maintenance, ranking roads for improvement in terms of economic feasibility, by analysing data from road condition and traffic surveys, and developing estimates for cost improvement and maintenance.

Pavement types vary We combine state-of-the-art methodology and – the largest game reserve in Africa from flexible pavements through semi-rigid expertise to reach sustainable and cost-effective to rigid concrete pavements. solutions. At the same time, we are dedicated to the utilisation of available technology and materials, always observing environmental requirements. Paved areas may be subjected to a wide variety of loads. From rubber-tyre vehicles moving at high to moderate speeds, through forklifts with solid wheels of high stiffness to stationary loads created by parked vehicles or stacked containers.

Road safety is a growing concern and our state-certified road safety auditors carry out Bangladesh Road Safety Project. Public campaigns and police audits on both existing and planned roads as enforcement are some of the measures being introduced to well as black spot analyses. They also develop improve driving habits and road safety. Financed by NDF specific safety action plans.

COWI provides design solutions for lighting and other electrical installations for new roads and for modernisation of existing facilities. Our consulting services cover all stages of a project including design and coordination with other agencies. Traffic information systems We can assist our clients in selecting the cor- rect solutions for traffic information systems, variable road signs that provide drivers with dynamic information, which increases road ca- pacity and safety, and COWI is always abreast of the latest technological developments. Our experience in providing electrical solutions for roads has been gained from many years of undertaking projects all over the world.

We have designed a large number of such terminals in co-operation with architects and landscape architects. Private and public transport Ferry harbours, large bus and train stations, and airport terminals are locations where the interchange between private and public trans- port takes place. It is important that the change can take place rapidly and safely, and with the least possible disruption for the passengers. Safe access, adequate parking facilities, logical location of ticketing facilities, short walking distances and easy-to-read time schedule in- formation are key words for the planning and design of terminals.
