Planners working on the design of a transit system for Honolulu released new computer simulations yesterday of what some of the options might look like.

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. Planners last week released another series of simulations.

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. Now 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 and conclude tomorrow, from 6 to 7:30 p.m. at the Aliamanu Middle School cafeteria.

Consultants also released renderings that show how a rail transit system might look as it travels near Aloha Stadium, Fort Street Mall in downtown, near Honolulu Community College, a makai view on University Avenue and in Waikiki.

In the coming weeks, the city expects to announce details of how much each alternative could cost and how many people might choose to ride on the different routes.
