By Guy Busby BAY MINETTE – Baldwin County’s public transportation system is launching an on-demand scheduling app to allow riders to arrange rides online. The Baldwin Rural Transportation System will offer BRATS On-Demand, a scheduling app that will allow riders to book trips around the county using their smart phone, similar to scheduling a ride-sharing service, Matthew Brown, system director, said Tuesday. “BRATS has served the citizens of Baldwin County for years, but as times change, so do kind of the demands of the population,” Brown said. BRATS was established in 1988. Until now, most riders had to call dispatchers at least 24 hours in advance to arrange trips. The scheduling booklet was 40 pages long and often confusing to system employees, including Brown.
