Map 1 shows the population density (2011 Census) across the study area, indicating very low density in the rural areas of Dartmoor and South Hams, with populations concentrated in Ashburton (4,000), Buckfastleigh (3,300) Ivybridge (12,000) and Plympton (30,000). South Brent has a less dense but still significant population of 2,800. The map clearly shows that the vast majority of local trips within the A38 corridor between Plymouth and Ashburton will originate in the towns along the corridor. Trip destinations For the purposes of this study we have considered only employment sites as trip destinations using 2011 Census data on location of employment. Other major destinations could include shopping centres, schools and colleges, and health facilities. However, considered across this wide area, these facilities are generally located within the towns, so are assumed to be included within the towns as destinations. The key destinations on this basis are seen on Map 2 to be Ashburton, Buckfastleigh, Ivybridge, Lee Mill and Plympton. The central and southern part of Plymouth city are indicated This map was produced by by Rupert Crosbee on 17 May 2017 as major employment destinations, justifying Scale 1:100000 the extension of this study into the centre of the city. 2 South Dartmoor Towns August 2017 Desire lines Location of Map 2 Desire lines Considering the origins and destinations along Desire Lines the A38 corridor, Map 3 shows the desire lines employment for travel between these points. These largely Map 3 follow the existing NCN route 2, also shown on the map. The population density and employment density eastwards of Ivybridge, and the distances between settlements, suggest that the primary use of the routes in the eastern part of the study area are likely to be proportionally more highly used for recreation and leisure, in contrast to the route westwards from Ivybridge, where commuting trips are likely to be more prevalent.

Given the unpleasant conditions for originating in Ivybridge, Plympton and East cycling, and the poor quality of provision, this and central Plymouth – all origins lying on the would seem to indicate a high potential for a corridor of the NCN Route 2. shift to cycling if conditions were improved. The data has been sorted to include only those The Propensity to Cycling toll (www.pct.bike/) trips originating in these towns with destinations enables an assessment to be made using within the corridor between Ivybridge and baseline 2011 Census data of changes in Plymouth, including Lee Mill. cycling levels in a range of scenarios. The data is represented on the maps 5, 6 & 7. In the ‘Go Dutch’ scenario, where cycling levels Table 1 summarises the numbers of commuting equivalent to those in Holland are achieved, the trips originating in each settlement with a changes which would, according to pct.com, destination zone falling wholly or partly within occur are shown in table 2.
