Saunders said she looks forward to adding a second year of data, which will help identify patterns and show the impact of added infrastructure. The information is useful in deciding how and where to spend money from grants and the city budget, she said.Other factors that help determine priorities include census data, political and community support, neighborhood density and automatic counters, such as ones along Penn Avenue, Downtown. The Pittsburgh Downtown Partnership reports that more than 500 riders a day have used that bike lane since April. Other automatic counters are being developed for the city by Carnegie Mellon University students, Saunders said.
