AbstractThis paper describes a set of specialized spreadsheets that model the cost and performance of transit system options including light rail transit, guideway bus, express bus, and ride sharing. These spreadsheets are demonstrated by comparing a guideway bus (GWB) transit system and a light rail transit (LRT) system proposed for construction in an active rail corridor. The comparisons for assumed levels of transit ridership include guideway geometry, travel time, headways, vehicle requirements, grade crossing protection, and capital and operating costs.The planned GWB system runs on an exclusive dual guideway in the rail right‐of‐way, and the alternative LRT system operates on the existing rails with new bridges and track as needed for a dual guideway system. The analysis compares the two options for mode splits between 0.5 and 50. Results show that while both options have approximately the same travel time, the GWB system costs approximately 30 less than the LRT system. The cost difference results primarily from lower GWB vehicle purchase and operating costs.The spreadsheets are available through the McTrans Center at the University of Florida, Gainesville, Flor
