Scoring seems arbitrary

My neighbor one house closer to town has a score of 71 but drops to 49 for me. Shortly beyond my house is a highway. People on the other side need to walk an additional mile or more to get to the same resources. They are also 49. To be useful, this tool needs to take more into consideration that just distance and scores should not increase considerably based on round benchmarks (ie, - 22 pts for being slightly over .5 miles than slightly under).
