Why was there an increase and decrease in high way robbery in from 1700 to 1900?

The increase in highway robbery from 1700 to the early 1800s was largely due to the growth of trade and travel, which created more opportunities for criminals to target wealthy travelers. Factors such as economic hardship and the expansion of urban areas also contributed to the rise in these crimes. However, by the mid-1800s, improvements in law enforcement, the establishment of better road systems, and the introduction of the railway reduced highway robbery incidents significantly, as travel became safer and more regulated. Additionally, harsher legal penalties for robbery acted as a deterrent.
