Noise Levels<br />
Motorised transport contributes to noise in cities. In general noise levels near highways and<br />
expressways are high on account of fast moving transport; however, there is no systematic recording<br />
of noise levels. That said, it is quite feasible to monitor noise levels using mobile instruments to<br />
document the baseline situation.<br />
Task 2.8 Analysis and Indicators (Comparison with Benchmarks)<br />
Indicators provide an easy way to communicate a city’s transport status, or to make comparisons<br />
across alternative scenarios. The indicators <strong>for</strong> transport at the city level19(see Table 16) can be<br />
broadly divided into i) indicators <strong>for</strong> mobility and accessibility; ii) infrastructure and land use; iii)<br />
safety and security; iv) environmental impacts; and v) economic. Most of the indicators can also be<br />
directly linked to the Service Level Benchmarks 20. A comparison of the indicators to SLB is<br />
provided in Annex 4.<br />
The details of the selected indicators (relevance and data sources) have been furnished in reports on<br />
city level indicators. However, some of the indicators specifically related to investment trends and<br />
impact on af<strong>for</strong>dability might be difficult to use <strong>for</strong> business as usual and alternate scenarios (Table<br />
16).<br />
17 This is a relatively more expensive option than balloons however air quality over a 24 hour period can be<br />
collected in this fashion<br />
