Velindre National Health Service Trust (VNHST) has known for some time that these facts mean, without change, Velindre Cancer Centre (VCC) will increasingly struggle to meet forecasted levels of demand whilst continuing to deliver the highest level of care, quality, and patient experience in the 21st century. The proposed new facility will provide a regional cancer centre for South East Wales covering the Cwm Taf, Cardiff and Vale, Anuerin Bevan and Abertawe Bro Morgannwg (ABM) (Bridgend) health boards. This Transport Assessment has been prepared by Mott MacDonald on behalf of Velindre NHS Trust in support of the planning submission for the relocation of Velindre Cancer Centre. The new Velindre Cancer Centre (nVCC) will provide in the region of 39,000m2 of health floor space providing non -surgical critical services including: Radiotherapy, Chemotherapy, Pharmacy, Out patients, Imaging, and a small number of In-patient beds. In addition, the Maggie’s Centre Charity plan to build a support unit on the proposed site. The nVCC proposals have been developed within the context of existing planning and health care policies, which must be considered for the development to be aligned with the aspirations and objectives of the relevant planning bodies. Development Proposals The proposed development site is comprised of previously undeveloped land currently not accessible by vehicles from the highway network. It is situated on the northern outskirts of Cardiff, approximately 2km from Whitchurch Village, 6km north of Cardiff City Centre and 400m from Coryton Interchange, giving good connections to the M4, A470 and the local highway network. Adjacent developments include the Whitchurch Hospital site, the residential areas of the Hollybush Estate, Clos Coed Hir, Coryton Railway station and ASDA Superstore (Coryton). The proposed development consists of the cancer centre and associated infrastructure that includes the vehicle main site access route, an emergency vehicle access route, internal site roads, a new pedestrian access, pedestrian linkages to Coryton Railway station, vehicle parking areas, internal pedestrian routes and associated utilities infrastructure, public realm, and landscaping. Proposed Site Access Arrangements The main site access would be provided from the north of the site via the existing roundabout on Longwood Drive. It is proposed to upgrade the roundabout and the arms that serve Longwood Drive / Coryton Gyratory junction and the ASDA Supermarket site. A new access road would spur off from the ASDA access road to the south-east of McDonalds, across the disused railway cutting via a 3- span bridge and enter the main site area through the north-west boundary. The bridge location allows an optimised highway alignment, minimising the number of curves in the road and maximising the length of existing road used, thus reducing the cost and environmental impacts of the road construction. The proposed alignment would provide a 6m wide road giving two-way vehicle movement and a shared pedestrian and cycle lane. A secondary ‘emergency only’ access is proposed from the Hollybush Estate; this access would only be used in the event of an emergency and gated to prevent other vehicular access. Pedestrian access to the east of the site will be provided by the existing bridge with an upgraded footway. 361662 | 01 | A | 23 March 2017 C:\Users\cha77685\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\37W3G4O3\Velindre CC Transport Assessment Final (002).docx Mott MacDonald | Velindre Cancer Centre Relocation 2 Other upgraded pedestrian and cycle accesses would be provided from Pendwyallt Road and Coryton Rail Station connecting in to the local public rights of way near the site. Proposed highway improvements To improve traffic flow on the development access roads some modification of the Longwood Drive road lay-out is required. This includes; ● Modification of the stop line widths on all arms of Longwood Drive Roundabout ● Increasing the inscribed circle diameter from 23m to 28m and reducing the island radius from 3.5m to 2m radius ● Extension of the two-lane approach on Longwood Drive East from 20m to 60m to provide a dedicated left turn for access to ASDA and the proposed development. ● Provide two lanes increasing to three from Longwood Drive Roundabout to Coryton Gyratory signalised junction rather that the present one lane to three lane configurations. The ‘emergency only’ access from Hollybush Estate is proposed as a bridge deck with a single unmarked 5.5m wide carriageway with 0.6m wide verges on either side, providing adequate carriageway width for emergency vehicles to pass each other on the structure. Sustainable Transport Sustainable transport and active travel was considered in line with the requirements of the Active Travel (Wales) Act (2013) and Cardiff Council’s Local Transport Plan (2015 – 2020). The availability of bus and rail services in the locality have been identified and included in the development strategy. The VNHS Trust is in talks with local bus operators to provide services directly into the site. The Transport Assessment shows the current plans to connect the existing walking / cycle routes to the development and proposed new routes from Coryton station and adjacent to the northern access road. The report includes the current Velindre travel plan, which will be updated for the new hospital location. Trip generation The traffic flows were assessed for three years: 2016 (Base); 2022 (Opening); and 2032 (Design) in the AM and PM peaks. Base traffic data was obtained through a traffic survey programme on the local highway network in 2015 and 2016. Microprocessor Optimised Vehicle Actuation (MOVA) data was supplied by Traffic Wales in 2016 from the Longwood Drive / Coryton Gyratory signalised junction assessment. Future year growth was determined by applying TEMPro Interim v7.1 growth factors for the Cardiff 010 area and the National Transport Model 2015 traffic growth dataset for urban principal roads, adjusted using WebTAG factors for forecast fuel price and income changes. The resulting background traffic growth show a forecast increase of 12% between 2016 and 2022 and 30% between 2016 and 2032. Development trips have been generated for staff, patient, deliveries, and other ad-hoc trips associated with the hospital and applied to the base and future year flows.
