[Closed] Anyone on here work on traffic modelling?

Sounds familiar, similar thing here.
District borders along the road other district wanting to put shitloads of houses in on their side with roads already struggling as it is without all these extra houses.

Not traffic modelling but other kings

Ideally the modelling report needs peer reviewing but any help on what to look for greatly appreciated.

Is there going to be new access roads, different traffic routing etc.

Objections would still have to go via the planning route so you are probably better getting some general planning advice first, form a local action group etc. get some banners.

Where is the development?

2000 houses? There must be a desperate shortage of houses in that area.
They have to be built somewhere.
If not in the field behind your house where else would you suggest?
I know it's not good.
You'd be better off looking at the flora,fauna,lizards,newts kind of thing if you don't want them built.

It's south west taunton. Yes new access points including new roundabout on the a38.

There are a couple of issues for me. Eg the modelling says a certain roundabout will be well over capacity even with mitigation. So the solution is to manage demand. But the demand forecasts already include park and ride and 35% of people walking to school or work. So if I read it right, it just then ignores the issue!

And another bit says a 6.1m uap3 road which has a 220% increase in traffic is fine as this type of road can take 900 cars per hour, but they ignore the fact that the road has a stop junction at the end and cars parked on it which the guidelines (I looked) said the figures don't include the effect of these. Looks all a bit cack to my untrained eye!

I'm going to buy some newts and badgers and put them at the back of our house!

I'm resigned to the fact they will be built but I think the traffic stuff is underestimated. My road is a single track road and they ignore it as they say it won't be a rat run....

You are correct that a network model would be better than a set of standalone models to see the true effect - as you say they interaction between junctions is as important as whether the junctions themselves are within capacity. The technical data on the junction models would include queue lengths that would allow you to get a feel for whether this is an issue if you measure the links between the junctions (Google Earth). The flipside of that is that network models are often better at dynamically assigning demand and balancing the demand over the road network.

If this is an allocated site included in local planning documents then the local authority are likely to support it. And if the planning document has been adopted as local policy then that means the authority will back the sites in that document so long as they are developed within the bounds of other policy.

Large developments will inevitably increase local traffic and creating additional road space is not always a good move as there are always pinch points in the network; so in effect an improvement somewhere often just moves the problem on.

What I would be looking at in detail is the measures the development will be putting in place to encourage sustainable transport. For 2,000 units these should be pretty significant and be a realistic alternative for employment and school travel both to the development and the wider community. For instance do the measures put forward look reasonable to generate 35% of people walking to work/school. Pushing for increases to these is more likely to gain council backing than opposing the whole site if it has wider policy backing. As mikewsmith says diving too deep into the modelling detail is often unrewarding.
