Several U.S. cities have used isochrones—lines that connect geographic points on a map to compare transit travel times—to redesign their transit systems. But the city of Richmond, Va., is using a new interactive tool that takes isochrone-informed transit planning to the next level.
As a design-build team of Lane Construction Corp. and STV Inc. nears completion of Pulse, a $65-million, 7.6-mile bus rapid-transit system, city officials commissioned Michael Baker International and Jarrett Walker & Associates to study how best to improve the existing bus system to maximize efficiency of service in conjunction with the new line.
