Jakarta’s city administration is to begin work on building two dual-purpose tunnels by the end of the year in an effort to address increasingly dire conditions on the capital’s gridlocked, flood-prone streets.

Private building contractor Antaredja Mulia Jaya has been awarded a contract for the Jakarta Integrated Tunnel (JIT) project, which will incorporate two tunnels is set to measured 11 metres in diameter and 12 kilometres in length, from five to 15 metres below ground.  The tunnels have been designed to carry flood water and traffic on separate levels, at a projected cost of US$2.92 billion.

“The JIT development will be in collaboration with French investor Bouygues,” Antaredja head Agus Sidharta said on Friday at City Hall. Agus said his company would work with Jakarta’s toll road developer to build and maintain the road portion of the project.

    For major road works schemes, necessary lane closures are timed to minimise congestion, most frequently at night and on weekends when traffic is at its lightest. As a result, rigid timetables are used in planning, programming and implementing work. In the UK, to calculate the expected traffic demand through roads works, historic profiles from the loop-based MIDAS (Motorway Incident Detection Automatic Signalling) system were used. These provided a valuable indicator of anticipated traffic behaviour but were

    UK Chancellor George Osborne announced major investments in transport in the government’s Spending Review and Autumn Statement, despite a 37 per cent cut in the Department for Transport’s (DfT) operational budget. This was offset with a planned 50% per cent increase in capital expenditure for the DfT - rising to a total of US$92 billion. In addition to protecting overall police spending in line with inflation, an increase of US$1.3 billion by 2019-20, the review includes US$70 billion capital investment

    Rather looking to solve congestion by spreading the load, perhaps we need to look at concentrating it. Michael L. Sena writes. We humans were made to walk and run at embarrassingly slow speeds by comparison with other, more fleet-footed organisms. The sea is not our natural habitat and we were definitely not designed to fly unaided. Nevertheless, humankind has evolved a method of living during the past century that is dependent on transporting its members over very long distances during relatively short per

    Public acceptance is crucial for the acceptance of managed and express lanes as Jon Masters discovers. Lists of proposed highway expansion projects introducing variably priced toll lanes continue to lengthen. Managed lanes, or express lanes to some, are gaining support as a politically favourable way of adding capacity and reducing acute congestion on principal highways. In Florida, for example, the managed lanes on the 95 Express are claimed to have significantly increased average peak-time speeds on tolle
