may shift if the proportion of trips cycled increases in the city. The results also suggest that cycle paths built to help achieve ambitious targets, as represented by the Go Dutch scenario, should be of sufficient width to accommodate the estimated flows. ## [1] FALSE Another output that can be highly policy relevant is the difference between ‘fast’ and ‘quiet’ routes. Figure 9 illustrates this by showing the Fast & Quiet Routes layer in Manchester with the highest cycling potential under the Government Target scenario. The ‘quiet’ route is longer: 2.8 km (as shown by clicking on the line) compared with the more direct fast route which is 2.3 km. However, the ‘fast’ route may not currently be attractive for cycling as it passes along a busy dual carriage way. The Euclidean distance associated with this OD pair is 1.6 km (this can be seen by clicking on a line illustrated from the ‘Straight Lines’ layer in the PCT’s interface), resulting in ‘circuity’ (see Iacono et al., 2008), values of 1.6 and 1.4 for ‘quiet’ and ‘fast’ routes respectively. Dutch guidance suggests that circuity values “for cycle provision should be 1.2” (CROW, 2007). Evidence indicates that women and older people have a greater preference for off-road and shorter routes (Garrard et al., 2008; Woodcock et al., 2016). This suggests the ‘fast route’ option, if built to a high standard, may be favourable from an equity perspective in this context. ## [1] FALSE Three basemap options are worth highlighting in addition to the grey default basemap. These were selected to provide insight into how the geographical distribution of latent demand for cycling relates to current cycle infrastructure and socio-demographics: ‘OpenCycleMap’ indicates where cycle provision is (and is not) currently; ‘Index of Deprivation’ illustrates the spatial distribution of social inequalities; and the ‘Satellite’ basemap can help identify opportunities for re-allocating space away from roads and other land uses for cycle and walking paths by providing visual information on road widths and land uses along desire 26
