A guide to the terms we use

Low traffic neighbourhood (LTN)

Low traffic neighbourhoods are an area where motorised traffic is prevented from taking shortcuts through a residential area by means of traffic filters. This creates quieter and safer streets where residents may feel safer and more comfortable when making local journeys by bus, by cycle or on foot.

Experimental traffic regulation order (ETRO)

LTNs will be implemented via a legal process called an Experimental Traffic Regulation Order (ETRO). ETROs are used when it is very difficult to assess the impacts of the scheme beforehand, but the cost of implementation is relatively low.

In an ETRO, the council introduces the scheme as an experiment first and there is then a six-month period after the scheme is introduced when the public can see for themselves the impact of the scheme and the Council can monitor its impacts. At the end of the six-month period, the Council assesses the impacts, including any letters of support or objections, and decides whether to confirm, cancel or extend the ETRO for up to 12 months longer to allow further consultation and monitoring.


Quietways are signed cycling routes linking key destinations that follow backstreet routes avoiding some of the busier highly roads in the area. These are great for people who prefer a quieter journey and can also help overcome some of the barriers that might prevent less confident cyclists from getting on their bikes. Some quietways need just signage, other quietways will be dependent on reducing traffic through the proposed LTNs.


Quickways are cycle routes linking key destinations via main routes into the city centre. They are designed to provide a direct faster route into the centre and are generally used by more confident cyclists. The proposed measures are either permanent or have the potential to become permanent. However, some may be introduced on a trial basis initially.
