"The city council in late 2012 voted almost unanimously in favour of a<br>
city-wide 20mph speed limit to improve pedestrian safety, lessen<br>
traffic congestion and reduce pollution. The roll out of 20mph speed<br>
limits across Birmingham will begin in the city centre and inner city<br>
wards despite resident objections, it has been announced."<br>

<br>
In Luxembourg, we used a similar roll-out of speed limits to<br>
completely map the speed limits in the city, following the council<br>
quarter by quarter as they rolled out the restrictions. Shall we try<br>
to do the same in Birmingham?<br>
<br>
These are the speed restrictions as we have them now:<br>

<br>
By the way, what is the scope of a speed restriction sign in the UK?<br>
Is the sign valid until the next crossing, or until the next sign<br>
indicating a change of speed? I have seen both systems used in other<br>
countries.<br>

Its valid until the next sign. In fact department to transport guidelines<br>
are to NOT put repeater 30mph signs in built up street lit urban areas.<br>
<br>
If a side road at 40mph joins a 30mph road then there will be a 30mph sign<br>
at the end of the side road (just before it joins the main road).<br>
<br>
Coventry rolled out a 20mph "zone" in the city centre. At each entry to the<br>
"zone" they have to put in a speed "gate". This makes mapping much easier<br>
as you just need to survey the gates (all roads inside are 20mph). When<br>
Coventry did it they provided a map - so I just walked around with that,<br>
photographed the precise gate location, mapped them in OSM as nodes away<br>
from the road (less likely that they will be moved accidently) and then<br>
split the road way and added maxspeed.<br>
<br>
Is Birmingham releasing a map?<br>
