Designing city road networks
Today, city road network design is informed by a wider range of transport, social and economic goals, leading to a network that is safe, easy to navigate and balances the needs of all road users.
This has become increasingly important as cities simultaneously densify, tackle pollution and meet net zero goals. During the design phase, Arup helps in a number of ways:
Optimising and consolidating the network
We design city road schemes around community needs, not just to address capacity, maintenance or congestion issues. This means shaping schemes to encourage a mix of road use and travel options. It also means ensuring existing networks are shaped to suit a town or city’s current and future priorities and strategy. For example, our work designing active travel schemes around the world puts safety at the heart of how different road users interact on one network.
Reconnections to nature
Today, many road schemes present valuable opportunities to reconnect urban areas with open spaces and nature. Our work on the Presidio Parkway in California, demonstrates what’s possible when bold thinking and a commitment to the environment are allowed to inform road planning. The completed scheme has led to 14 new acres of new community parkland while revitalising road connections from the Golden Gate Bridge to San Francisco.
The gateway to the Golden Gate Bridge since 1936, the ageing Doyle Drive was no longer capable of serving its 100,000 daily users. In designing a replacement, careful consideration was needed to minimise disruption for commuters and create a long-term transport solution in harmony with the landscape with minimal impacts on the Presidio National Park.
The simple design idea that united everyone was to create not a highway, but a parkway. To create something capable of improving everyone’s experience, we worked closely with sponsors and stakeholders to develop the design concept for Presidio Parkway. We also developed a robust financial and project delivery plan that was affordable and minimised short- and long-term risks.
The Presidio Parkway project was one of the first in the country to incorporate extensive sustainability features, setting it on a path to becoming the first Greenroads-Certified highway in the country.
