The London Assembly is seeking views on the impact of the rising number of delivery vans on the capital's roads.

In a survey launched last week, the assembly's transport committee is seeking feedback on how vans contribute to traffic congestion, air quality and safety in London.

It also wants to understand which alternative delivery methods businesses and residents would consider and how much they would be willing to pay for more sustainable logistics.

This would include options such as Click & Collect, consolidation centres with last-mile delivery in a zero-emission vehicles and a move to enable more out-of-hours deliveries in London.

According to figures from Transport for London (TfL), light commercial traffic makes up 13% of all London’s road traffic, compared with 4% for HGVs and 1.7% for buses.

During the morning peak, this equates to around 7,300 vans per hour and 21.5% of traffic km.

Light commercial traffic is expected to increase by 22% between 2011 and 2031, while HGV traffic will remain static, which is attributed to the continued growth of online shopping.

Last week's survey is the latest stage in a wider investigation underway by the London Assembly on the light commercial vehicle sector in the capital, which aims to work with all stakeholders to explore more sustainable delivery methods. It will be used to help shape TfL's freight strategy.

The survey closes on 31 December.
