Freeway – Congestion Slide Show

This Congestion Slide Show page is another way to present each corridor's recurring congestion lever which is similar to the Storybook page.  The storybook applies interactive style which allows the users to select page or automatically turn the page to compare each different month's congestion. Each slide provides user a quick overview of the historical freeway performances. By comparing each month’s congestion page, the impact of construction activities, ramp meter strategy changes, striping modifications, and freeway capacity increase (HOV lanes open) can be easily observed by users and decision makers.

How to use:

1.       Select the corridor first. Each corridor's congestion is compiled into one set of slides;

2.       Slide will automatically turn to the next page after user clicks on the play button. Or jump to the slide by clicking on the thumbnail picture of each slide on the bottom;

3.       Click on the full screen button to make this slide show in full screen mode.


·         Currently, Congestion Slide Show is still a demo version which only shows the congestions of the urban freeway segments from year 2009 to 2011.


How to read the book:

1.       Each page is the summary of the typical congestion of the specific month;

2.       Monday through Thursday, Friday, and weekend have their own section on each page because Las Vegas Metropolitan Area has different traffic characteristics on these days;

3.       Congestion severity is depicted by the colors (green means lighter congestion while red means heavier); Congestion extension is shown by the colorized columns (each column represents a freeway segment and duration), the longer the colorized rows, the wider the congestions; Congestion Duration is listed by the rows (each row describes each hour), the more colorized rows, the longer congestion experienced; Typical Travel Times of each hour is shown on the left accordingly;

4.       On this I-15 Northbound congestion demo page, the direction of travel is from the right to left, from Beltway Interchange (I -15 / US-95) to the Spaghetti Bowl Interchange (I -15 / US-95);

5.       The express lane project construction in July and August 2009, adding the 3rd lane of Tropicana ramp meter, partially opening HOV lane to Flamingo, and fully opening HOV lanes can be easily observed from each page by users, professionals, and decision makers.


·         The congestions shown in this demo are recurring congestion without crash impact.
