Scenario 6:
A "Virtual Highway"

Virtual Highway

The Policy

  • To preserve the City of Cambridge and its surrounding area much as it is today.

  • New development only allowed within limited distance of high capacity communications network to reduce environmental impact of private car travel.

  • No other additional buildings within the City and South Cambridgeshire beyond existing planning permissions.

  • Some new development allowed in market towns of Ely, Huntingdon, St Ives, St Neots.

  • Replacement or renewal of buildings allowed within the City and South Cambridgeshire (e.g., conversion of houses into flats, or warehousing into offices, etc).

  • Requires improved high capacity electronic communications system e.g. underground broad band fibre optic cable with localised aerial transmission to surrounding buildings.

This policy envisages a smaller increase of households in the City. Larger increases will be seen along the communications virtual highway especially in South Cambridgeshire and Huntingdonshire.

Employment continues to grow in the City despite the restrictions due to existing permissions for development, substitution of extensive space users by intensive users (e.g., high-tech business, private and public services) but is balanced by growth elsewhere on the virtual highway

The Results

  • Restricted housing supply leads to some cost increases within the City

  • Displacement continues of middle and lower socio-economic groups in the City and South Cambridgeshire by wealthy managerial and professional groups

  • Production costs increase in all areas, slightly less in Huntingdonshire

  • Displacement continues of traditional jobs in the City by more competitive, high-tech and private service jobs

  • Reduced need to commute for work and services which would significantly reduce the increasing commuting into Cambridge and its fringe, thus controlling emissions and pollution.

The cost of living would rise, especially within the City, due to increased house prices and rentals, costs of goods and services.

The cost of production would increase substantially, especially within the City and South Cambridgeshire, due to increased labour costs, floorspace rentals and congestion.

Transport implications

  • Reduced need to commute for jobs or travel for services could cut down trips by private car.

  • People using the virtual highway may move further away from their places of employment.

  • The majority of trips would still be by car as public transport is unsustainable with dispersed population, but with reduced congestion, emissions and thus pollution.

  • Benefits of reduced car use countered by increased average trip length.

  • Would necessitate significant investment in communications infrastructure.

Evaluation

Efficiency

  • Economic efficiency may be impaired because of restrictions where demand is high, putting at risk the competitiveness of the region.

  • Export-oriented firms such as the high-tech sector would find it difficult to compete with the rest of the world, as it would face around 40% increase in production costs (between 2001 and 2016).

Equity

  • The City of Cambridge would continue to become more segregated through the concentration of high-income groups.

  • South Cambridgeshire would also become more segregated.

  • Lower socio-economic groups concentrate in East Cambridgeshire and Huntingdonshire.

Environment

  • Good protection of the environment in the City.

  • More intense utilisation of land around the virtual highway would reduce green land and increase emissions and pollution locally.

 

 

The Virtual Corridor

The illustration above shows an area where additional development could be connected to the virtual highway. The area illustrated is the M11-A14 corridor connecting Stansted airport to Alconbury airport. Within a certain distance from the corridor, new villages could be hooked up to the superhighway, allowing instant multimedia communications.
