Portsmouth is a vibrant and growing coastal city with big city challenges of congestion and air pollution.
What do we need to do to ensure Portsmouth stays an attractive place to live, work, visit and study? Can we tackle congestion and air pollution to help the city thrive? Š CC BY-SA 4.0 3
→ 36% of children in Portsmouth show indications of potential metabolic disease.
→ Children and babies in Portsmouth smoke equivalent of 550 cigarettes/year due to air pollution.

Most of Portsmouth lies within cycling distance of the city centre, and there is great potential for local walking.
Note: these dotted lines represent as-the-crowflies isochrones, which give us a quick overview of the potential for walking and cycling.

The A2047 is a 5km/3mi northsouth corridor which has community as well as transport importance: + Community assets (shops, cafes, bus stops) + Proximity to local residential areas and city centre + Existing public transport routes + Interesting architecture - Congestion - High air pollution - Traffic safety issues - Inconsistent footway quality
A main high street section runs for 450m from Stubbington Avenue to Kingston Crescent, however the high street/community character extends beyond this to the north and south.

High Level Capacity Analysis â&#x20AC;&#x201C; Key Assumptions Overall Mode Share - Modal share taken from Census 2011, QS701EW Method of travel to work, as a proxy for total transport modal share. Therefore of total respondents (153,705), unemployed and working from home were excluded, resulting in a sample of 93,339. Under- ground, metro, light rail, tram, train, bus, minibus or coach are combined as public transport. - Future proofing is based on 1% modal share increase per year respectively for walking, cycling and public transport over 1 decade, with a resultant net reduction in car modal share. Street Level - Street level transport data was derived from a CCTV traffic count survey conducted on London Road in August 2018. - This survey data corrected with 8.5% August bias, derived from National Travel Survey NTS0506 (DfT, 2018). - Walking modal share derived from Census data for Portsmouth (17%) but corrected for overall transport bias that Census data underrepresent overall walking levels; this still may be a risk of underestimate in a high street setting where there may be higher levels of walking. - Buses and coaches occupancy estimated as 40 seats per vehicle operating at 25% capacity. - 5% growth is presumed to 2028 (ONS, 2018). Portsmouth Inspiration Study: London Road A2047
Scenario A - Healthy High Street In this scenario, no private motorised vehicles would access the high street meaning a daily reduction of 11,469 car journeys through the high street. Through-journeys would covered in part by a modal shift onto a parallel cycle street, and in part by journey displacement to other existing arterial roads (M275, A2030, A288). Local journeys are converted into 50% more bus journeys, 50% more walking, and 50% more cycling. HGVs remain the same, but 50% of light freight (OGVs) is displaced onto e-cargo cycles. Overall, there is an increase in healthy transport from 46% to 84%. Scenario B - Transition Healthy High Street This scenario explores a transitional phase to the full Healthy High Street where initially 4,014 private vehicles are permitted, for example by allowing access during off peak times only. In this phase, theoretically no car displacement is needed to the other existing arterial roads (M275, A2030, A288), as the other 65% of vehicle journeys are covered through a modal shift to the parallel cycle street, and increases in pubic transport and walking journeys. This still represents a substantial increase in healthy transport to 81% Scenario C â&#x20AC;&#x201C; Max In this ultimate sovereignty scenario, there are larger modal shifts to buses and walking, which together with the parallel cycle street achieve a total of >90% healthy transport.

Routing Concept
Enhanced Junction
London Road A2047
Headline concepts: + Prioritise the high street â&#x2020;&#x2019; people. + High flow, low speed environment <12mph. + Reduce to two lanes two way, bus traffic. + Traffic exclusion 24 hours or at peak times. + Visual narrowing on road, remove centre line, upgrade character of surface material. + Assets zone, declutter, unify footway. + Four raised level zebra crossings. + Parallel cycle street as main through route for cycling. + Upgrade secondary junctions to continuous level footways.

Raised level Zebra crossings
Parallel Cycle Street Full specification, safe cycling for everyone
Chichester Road
Kingston Road
Kingston Crescent Additional considerations: + Alternative: bus traffic one way, to free one lane for bidirectional cycle track. + Potential to convert A2047 north and south of this area to 2 lane vehicle/bus traffic, 2 lane cycle traffic. + Potential to upgrade northern section Copnor Road A288 with cycle tracks.

London Road → A++ Healthy Transport Corridor Quality approach combined with…
…an Operational approach.
+ Prioritise the High Street experience.
+ Reduce to two lanes, two directions, bus priority.
+ Create assets zone with trees, seating, cycle parking, loading, disabled parking. + Declutter, consolidate assets in assets zone. + Add substantial cycle parking to facilitate east/west arrivals. + Add more frequent east/west zebra crossings, upgrade major junctions at Stubbington Ave and Kingston Crescent. + Remove barriers such as ‘cattle pens’ at pedestrian crossings. + Create an enabling and pleasant environment for more vulnerable users such as children, older adults or disabled people.
Portsmouth Inspiration Study: London Road A2047
+ Change road visual character, e.g. red bus surfacing but remove centre line, adding visual narrowing → low speed environment. + Main cycle through-traffic on parallel cycle street environment.
+ Local north-south cycling limited, in low speed, bus priority environment. + Traffic exclusion order to exclude private vehicle use (peak times, or 24 hour) + Loading at set times.
+ Transfer light freight (vans) onto e-cargo bikes.

Child cyclists are over 15 safer per mile cycled in the Netherlands compared to the UK. Continuous level footway crossovers are key to providing greater safety for both cyclists and pedestrians.

Material Details
+ Consistent material wayfinding. + Reasonable cost materials that can be maintained within standard maintenance operations.
Option 1 – ‘Dutch brick’ + Carriageway material - brick coloured asphalt similar to existing bus lane highlighting ‘healthy transport corridor’. + Cobbled visual narrowing/rumble strips.
Option 2 – ‘Oxford orange’ + Carriageway material orange-tone asphalt that gives a heritage feel. + Cobbled visual narrowing/rumble strips.
‘Pedestrian yellow’ + Footway material - yellowtone asphalt that gives a heritage feel. + Clear visual language for pedestrian priority over crossings.
