Businesses are keenly aware of the value and benefits of mapping out all of their stops before starting their deliveries to ensure they make the most efficient route while minimizing backtracking and preventing uneccessary cost and mileage. The same principle applies to the trips and travel we make as individuals. Planning out all of the errands we need to make, and doing them in one trip rather than in multiple outings can save us huge amounts of gas, money and time. It can also reduce the impact of our individual travel on traffic congestion.
