Walk Score has released a widget that websites may add to any Google Map to show travel-time estimates during rush hour.
If a website adds the widget using code provided by Walk Score, visitors may click the Rush Hour button on the Travel Time Widget to see travel times that factor in peak rush-hour congestion.

A person may use the widget to see on a map how far he may travel from his neighborhood within a specified time by walking, or using a bus, bike or car.
Soon the site will integrate rush-hour estimates into its commute-time feature, so that people who visit any of the 20,000 sites that use the Walk Score Neighborhood Map may use the feature to gauge commute times from one destination to another during peak and off-peak traffic hours.
