In practice many placemaking projects involve public spaces that are also near or part of a road. It is essential to consider traffic, both vehicular (including cycles) and various categories of pedestrians – people with disabilities and children.

Every road, street or lane forms part of a road network organized into a hierarchy of practical purposes that provide a wider area with essential communication. Some adjustments to the network are easier to achieve than others.

Roads are sometime considered as pipes, though allowing for the flow of traffic rather than water. The flows and capacity of traffic in relation to a road can be measured so that any adjustments to a road’s nature can be anticipated and dealt with.

The relationship between road safety and vehicle speed is key because where traffic cannot be removed, lower traffic speeds may be an acceptable alternative.

Road junctions are often critical as this is where vehicle paths cross, causing possible danger, delays and congestion.
