Transport planning โ€“ time to reimagine the rules For transport planners, opportunities to think outside the box are few and far between, writes James Gleave, Director of Mobility Lab, in this guest blog.

Is it time to reimagine the rules that govern transport planning?

"To make the radical changes that our climate goals and society demand of us, our written & unwritten rules need to be challenged," writes James Gleave of Mobility Lab in this guest blog:

Good to hear. My perception of it in Bristol is mixed. Drivers are more likely to give way when Iโ€™m out with my kids (as was found in the study) on the way to nursery or on the high street. But there are certain junctions where drivers rarely give way (likely due to traffic volume & road design)

Estimating the benefits of active travel investment Examines how economic appraisal can be done more effectively for active travel interventions that do not fit into existing frameworks.

ICYMI. A report for Active Travel England on estimating the benefits of active travel was published last week.

Looks to be a helpful summary of some of the key appraisal issues and identifies the interventions that can do badly under the current approaches (eg traffic reduction & area wide schemes)

Everyone needs access to trees and green space. Not just those who live in the countryside, or who have a car and can drive there. Not just those who can afford to live on leafy avenues with big gardens. Street trees and parks in urban areas are absolutely essential - and will become even more so.

We shouldnโ€™t have to escape the city for a daily dose of nature, no matter how short or small.

By challenging the privilege of the car on our streets, we create new opportunities for re-greening them; thus boosting our physical, mental, and social well-being.

When does the next bus come? GoTriangle reduces wait time on its busiest routes The regional agency joins GoDurham and GoRaleigh in offering bus service at 15-minute intervals between Durham and Chapel Hill.

Raleigh increased bus service from every 30 min to every 15 min on its route serving Glenwood Ave. Ridership then doubled in the year that followed.

Over last year, cityโ€™s high-frequency routes have had 89% ridership growth.

People will ride when you give them service that they can rely on!

Tesla hit with $243 million in damages after jury finds its Autopilot feature contributed to fatal crash The verdict follows a three-week trial that threw a spotlight on how Tesla and CEO Elon Musk have marketed their driver-assistance software.

A hugely important verdict.

The victims were pedestrians, so Tesla can't argue they knew/accepted Autopilot's risks.

People walking, biking, and inside other cars didn't consent to be Elon Musk's guinea pigs.

๐Ÿค” One of the most common questions weโ€™re asked when starting work with climate colleagues in local authorities is: โ€œHow can we persuade people to change their behaviour to reduce emissions?โ€

Important conclusion. Good communication can make a difference to how policies are perceived and avoid provoking unnecessary opposition. But, ultimately, for a policy to be perceived as fair it actually has to be designed to be so

Peopleโ€™s tendency to underestimate how much others support climate action is recurrent finding in empirical studies of climate policy support, and is a huge sore point for political climate action.
