His engineering work on the Holyhead Road (now the A5) in the 1820s reduced the journey time of the London mail coach from 45 hours to just 27 hours, and the best mail coach speeds rose from 5-6 mph (8–10 km/h) to 9-10 mph (14–16 km/h). Between London and Shrewsbury, most of his work on the road amounted to improvements.

The study does not count crashes that happen when walking across a roadway. The speed limit risk ratio was 1.116, which means that a 16.1-km/h (10-mi/h) increase in the limit yields a factor of (1.116) 10 or 3. [19] The presence or absence of sidewalks was one of three factors that were found to encourage drivers to choose lower, safer speeds. [20]

Brick paving machine. Brick, cobblestone, sett, wood plank, and wood block pavements such as Nicolson pavement, were once common in urban areas throughout the world, but fell out of fashion in most countries, due to the high cost of labor required to lay and maintain them, and are typically only kept for historical or aesthetic reasons.
