Yikes! Henry Allen's excellent article on traffic congestion {"Driving Us Crazy," Style, Oct. 21} was factual, comprehensive -- and scary. It's frustrating to think that the freeway -- once our best friend and final frontier -- has turned into a crotchety critter with a permanent snarl. While we may lament the passing of the mythical good ol' days, waxing nostalgic won't help highways flow faster. Our own choices will, though. Here are three ways we can keep our heads above "Q/K curve" quicksand.

Personal Choices. There is a visible problem that causes traffic congestion: too many cars in one place at one time. Did each of us have to drive to our destination? Did we have to drive at a peak time? Were there travel mode and time alternatives we could have chosen? We rarely think about such issues on a personal level: it's time to start. Inconvenient? Sure, but isn't gridlock worse?

Business Choices. Employers: Subsidize transit passes and van pools. Take a hard look at parking policies and costs. Encourage car pooling. Explore the feasibility of tele-commuting for some employees. Why bother? Lack of mobility hurts your business by affecting both your employees and your customers. Developers: Build transit-friendly projects, with less parking.

Public Choices. Congress: Stop taxing employer-provided van pool and transit subsidies as income while encouraging gridlock by making employer-subsidized parking tax-free. And shift more money into technologies that focus on moving people over moving vehicles. States: High-occupancy vehicle lanes work. So do the right thing -- build more. Local governments: Land use affects transportation choices. Sprawling subdivision designs make efficient transit -- or walking -- impossible.

To borrow Henry Allen's phrase, if we all work together there's "no visible reason" why we can't have mobility for all.
