Traffic flow information substantiates benefits of new route

The number of heavy goods vehicles (HGVs) travelling through Carlisle’s city centre in the north east of England is estimated to have been reduced by more than a third since the US$276.5 million Carlisle Northern Development Route opened in February 2012. Information gathered from a network of 20 permanent and temporary traffic counters dotted around the city showing ‘before and after’ CNDR road usage is starting to build a more meaningful picture of the benefits the new road has brought to Carlisle.

The number of heavy goods vehicles (HGVs) travelling through Carlisle’s city centre in the north east of England is estimated to have been reduced by more than a third since the US$276.5 million Carlisle Northern Development Route opened in February 2012.

Information gathered from a network of 20 permanent and temporary traffic counters dotted around the city showing ‘before and after’ CNDR road usage is starting to build a more meaningful picture of the benefits the new road has brought to Carlisle.

There has been a marked reduction in both cars and HGVs along the main north to south arterial route through the city – the A7 and A595 – as an average of more than 10,000 vehicles a day use the new 8.25km/5.13-mile road.

Carlisle’s busiest stretch of road, the A595 at Castle Way, has shown a 16 per cent reduction in all vehicles from 38,083 a day before the opening of CNDR to 32,050 afterwards (with a 41 per cent reduction in HGVs from 6,860 to 4,060). Other city centre hotspots have shown similar reductions, with the A7 at Stanwix Bank showing a 16 per cent reduction in all vehicles and a 32 per cent reduction in HGVs.

CNDR has quickly become a key route to travel between the south west of the city and the industrial areas to the north - a big factor for employers looking to develop good communications channels in areas ripe for commercial development.

As expected, there are higher levels of traffic on certain radial routes that have direct links to the CNDR. The county council has already set aside additional capital funding to mitigate against this effect and also improve links to CNDR for pedestrians and cyclists along these radial routes.

It was a key moment when Olympic boss Jacques Rogge signed off London 2012, calling the Games “happy and glorious.” Scarred by the logistical disaster of Atlanta 1996 and the last-minute building panic for Athens 2008, Rogge clearly thought London 2012 was an object lesson in how to plan and

    The extent to which ride-hailing has become a real force in the mobility landscape of San Francisco is great for consumers – but there are downsides, a report finds. Andrew Stone takes a look. Uber and Lyft, the two major ride-hailing platforms in San Francisco, are out-competing local cab firms in many ways - and are firmly established as a significant part of the daily mobility mix there, a recent study reveals. Researchers mined publicly-available data derived from the application programming interface

    Level 2 driver assistance vehicles have little problem reading fixed metal signs at the roadside - but it’s a different story with VMS in tunnels, finds Alan Dron. Following a series of hands-free driving tests in tunnels, an Australian road authority believes that car manufacturers have to up their game before vehicles have the required levels of competence to consistently perform ‘assisted driving’ tasks. The trials, in the state of Victoria late last year, tested the ability of several vehicles to stay

Nowhere is this more graphically illustrated than by the survivability statistics for the time to cardiopulmonary resuscitation of pre-hospital cardiac arrest: at four minutes the survival rate is 22% but by 14 minutes the survival has dropped to 5% - as can be seen from the graph below.
