The depictions show computerized before-and-after illustrations of the elevated transit options. The newest ones show what the managed lane, a dedicated road, would look like in two communities — near Pearlridge and near Honolulu Community College.

The city is studying the 23-mile traffic corridor from Kapolei to the University of Hawai'i-Manoa and Waikiki, which includes core residential and work communities on O'ahu. City planners said that area also is projected to absorb 69 percent of the population growth on O'ahu over the next quarter-century.

The new information comes from the city and consultant Parsons Brinckerhoff Quade & Douglas. Halfway through the study that will chart the path for Honolulu's transit future, engineers are describing the options at a series of meetings that began Saturday, continue from 5:30 to 7 p.m. today at the Mission Memorial Auditorium, next to Honolulu Hale, and conclude Wednesday, from 6 to 7:30 p.m. at the Aliamanu Middle School cafeteria.
