The purpose of streets and roads are to provide faster ways for citizens to get around in their vehicles
Three of the reasons were for more rapid troop movement, to connect the provinces, and to ease travel and trade.
The Roman roads were built for two reasons. The main reason was to move troops faster. The secondary reason was for civilian travel and trade. The roads made a link to all parts of the empire, by connecting the far away provinces with the capitol.
During the industrial revolution, the types of roads that existed were primarily dirt roads or cobblestone roads. Due to the increasing need for transportation for goods and people, there was a gradual improvement in road infrastructure, with some roads being widened and reinforced with gravel or stone, and others being paved with bricks or macadam. However, the quality and maintenance of roads varied greatly between different regions.

Most roads are not straight because they need to navigate around natural features like hills, rivers, and forests, as well as man-made obstacles like buildings and other structures. Additionally, road engineers often design roads with curves for safety reasons, as straight roads can lead to faster driving speeds and increased risk of accidents.

Because it was the quickest way from point A to point B.because sharp corners meant nobody could see around the corner in the war
Banked curves are the sloped turn ways usually on high speed roads (i.e. highways, race car tracks). This is to increase the centrifugal force(gravity) on the car so it does not skid off the road.

Curves are designed with a bank in them. In other words the curves are not flat. They have a certain degree of angle designed into the road. 2-5 degrees is not uncommon. This allows you to traverse that curve at a higher rate of speed than if it were flat.
