Decision Tree for Recommending Bicycle Facilities
In order to determine what type of facility to recommend for individual roadways , a methodology was developed for the City of Arlington . Utilizing such information as future roadway reconstruction schedules , existing roadway widths , existing roadway speed limits , and existing traffic volumes , the decisions were made through a decision-tree , as presented below .
