Street residents collectively regulating transportation movements in their street 

This type of engagement space has been proposed in brainstorms on city traffic management. 

Typical current situation

To avoid nuisance for residents, local governments set strict time windows for the supply of local businesses. The combination of time windows, opening times of local businesses, and delivery frequencies result in only partially filled vehicle driving around inefficiently planned routes. While the goal was to minimize nuisance of logistics vehicles driving around, the result is more vehicle kilometres. 

Engagement spaces alternative

The total amount of transport movements in and out the area is maximized by a collective agreement of the residents. A transportation company that wants to enter the (city centre) area must pay with a token. Tokens are distributed among the local business based on a measure collectively agreed upon by the residents. The number of possible deliveries now become scarce and local business need to adapt. For example, by reducing the number of deliveries per week or per month, or by combining deliveries with other businesses.
