You be the judge...

Update:
Thanks again for taking the time to offer your opinion. As of Tuesday, October 23rd we have closed the poll and the Vertical Graph is the winner by a nose. Thanks to your feedback (almost 800 votes), we will use this style of graph when we publish the best time to travel during the next holiday weekend. Even though the poll is closed we still welcome your comments letting us know which one works better for you. Thanks!

Original Post:
We have used several different styles of graphics to display the best time to travel during holiday weekends. Planning ahead by leaving a little later or leaving a little earlier will help you avoid peak travel times and arrive at your destination with minimum delay. We are hoping you could take some time and let us know which of these graphs helps you make that decision with the greatest of ease.

Which one is easiest to read? Which one makes more sense?


The Color Band Graph:



The Horizontal Graph:



The Vertical Graph:



The Clock View:






We are always looking to improve and we appreciate you taking the time to do this.

I appreciate the opportunity to weigh in on this. I think the vertical works best because it shows more information such as different levels of traffic throughout the day.

I like both the horizontal and vertical displays - easy for me to scan and interpret - though I think I prefer the "horizontal" that runs the time axis vertically since it mimics a "day planner" page

Nice that the WSDOT asks the sheeples. We will be watching to assure that the poll's overwhelming results are implemented.

The clock view works well but could use a legend to explain what the colors represent.

The Verticle display works well too and truely shows the best time to travel.

The Clock View graphs would be great if it showed 6 a.m. to 6 p.m. on one and 6 p.m. to 6 a.m. on the other. Though, it is nice to see the high's and low's of the vertical graph.

I voted for the clock display because it relays information quickly. But the clock hands should not appear the same or static; possibly they should be removed. Also, I see the colors coordinate with a traffic light, but it is more important the colors have high contrast and avoid misinformation to those who are color blind; I'd suggest adding the words heavy, light etc. - thanks for the opportunity to vote.

The vertical is very easy to read. Since we are trained to read left to right, it is natural to follow the graph progress through the day. Red is BAD!!

Where's the pictograph?

What about the other days of the weekend. I live north of Seattle and I am gone for several hours if not days. The one day of travel and the peak is great but what about the other days of the same weekend. I would like to see my best times not to go thru that area. On my returning or going trip. I know I am not alone on this I see lots of people packed going camping and boating. It would be ideal to see also the average traffic flow on top of this graffic of a normal day. How much of this is normal traffic and what is extra.

I'd like to know more about the purpose of the graph...

For driver information, I prefer the clock view, and agree that the hands can go... I also wouldn't mind a single 24 hr clock.

The clock view has the added advantage that it could be presented in a table with a clock view for each day without loosing impact for the user.

As for the bar graphs... I am personally more familiar with time tables displaying the hours along the verticle axis... the example labled as horizontal.

Tufte would be proud

I am in favor of the vertical graph - easy to read quickly and conveys maximum information.

However, I agree with the person living N. of Seattle (I do too) about showing all the days of a weekend or holiday weekend beginning with Thursday p.m. if a Friday holiday or Friday p.m. if a Monday holiday. To me, that array of information would be even more informative and helpful. Having all counties from Canada to the Oregon border would also help. Thanks for asking.

I find the Vertical nicely intuitive. It has lots of resolution in both dimensions, color coding for redundancy, and flows time nicely from left to right. It needs more days and all the hours. The clock graph and band graph are both too low resolution. The double clocks do not connect at noon and midnight which forces the brain into jarring jumps, and the hands are distracting. The horizontal graph can be misinterpreted due to small hours at the top and large hours at the bottom, and the horizontal bars might be misinterpreted as vehicle speeds.

The vertical display is best because it takes the brain the least amount of time to look and decipher the information while you are driving and/or reading a sign or publication.

The clock view is confusing for anyone wanting to travel mid-day. I like the vertical display best as it also shows the relative volume during light times.
Is there anything like this for border wait times for the Canada-US border? Wait times have gotten out of hand lately.

I find the vertical is the easiest to read at a glance. I hope that all the days being tallied would each have a graph, as times would be different on different days.

I prefer the Vertical chart overall. As a color-blind person, I cannot tell the difference between the red and green in the Clock style. On the others, the level of congestion can be determined even if one cannot discern the color.

Might be helpful to use "noon" and Midnight" inside of 12 am and 12 pm.

My vote is for the clocks or vertical graph they both have sufficient information and are easy to read.

The bold colors used in the horizontal and vertical graph make the different amounts of congestion easy and quick to identify peak times. I would make the legend text larger so it is readable, and also enlarged the hour numbers. I prefer the vertical graph because in English we do read left to right and the brain doesn't have to make any adjustment when looking at the data.

I prefer the horizontal graph, as it's so easy to scan down the left hand side and see the hours of the day and quickly see how bad traffic is. I don't think the vertical graph information can be assimilated as quickly.

Thank you for the opportunity to weigh in.

I like the clock view and agree with one person that looking at a 24hour clock would be interesting.

I also like the vertical view, but clock is better.

I prefer the horizontal graph because it makes it easy to scan down the left side for the time of day.

Thanks for asking for input!

The clocks are fun and unique, but I think that the vertical (or horizontal) graphs have more information. For instance, you can see the variety of "low" ratings for each time period.

I always love this type of information, keep it coming!

I really like the vertical. I am in agreement with the idea that it mimics my day planner. It is simple to read, and I get that not only is red bad, but it also shows the severity by way of length. There is no need for additional information such as the other graphs besides, I'm often in a hurry and want to glance at something, not sit there and try to decipher some crazy code. Thanks.

I like the both the vertical and horizontal graphs although I would prefer the vertical as it seems the easiest to read.

I like the clock - it's different, allows one to review with close attention - attention may yield to how we also commute / drive. THX
