In response to student complaints of overcrowding on buses, COTA has added additional bus service to two routes.The routes being affected are the No. 2, North High Street route and the No. 18 route, which runs on Kenny Road and through Ohio State, said COTA spokesman Patrick Bryant.”The frequency of the No. 2, which generates more than half of total student ridership, has increased during the mid-day and late evening,” he said.It now makes a stop every seven minutes from 11:30 a.m. to 4:20 p.m.; every 10 minutes from 5:30 p.m. to 7 p.m.; and every 12 minutes from 7 p.m. to 8 p.m., Bryant said.From spring quarter 1997 to autumn quarter 1997, there was a 50 percent increase in student riders, Bryant said.Currently, there are about 4,700 student trips per week day, he said.The No. 18, which travels from downtown through campus to the mall at Tuttle Crossing, will now make two additional evening weekday trips, he said. However, it will no longer travel to the OSU hospital because few people ride to the hospital.The USG/COTA student advisory committee would like to include later routes on the No. 84, which goes to the Lennox, said Kevin Cope, chairperson of the committee.”I would like to see my $9 a quarter go toward increasing the frequency of routes to the Lennox,” said Shelley Kuno, a senior majoring in criminology. “If I have to pay every quarter for the bus service, I want the service to be really convenient.”COTA recently conducted a survey at the request of the student committee, Cope said.The survey asked students how often they ride the bus, which routes they ride and what changes they want to be made to the service, Cope said.COTA doesn’t intend to make major changes on any routes without student input, Bryant said.
