Trip planner requires reality check
My father sent me an article [registration required] by a San Jose Mercury News columnist who regularly uses the local transit system, the Santa Clara Valley Transportation Authority (VTA). The columnist, Scott Herhold, decided to "test" the recently unveiled trip planner at the VTA website.
In journalistic parlance, "test" means to "poke holes," which is what he did. Using the Google-based trip planner, he rode a series of buses and trains to travel from his San Jose home to the Mercury News offices (in San Jose) to Fremont to Palo Alto and back home again.
What Herhold discovered was that the directions provided by the trip planner were, in some cases, impractical and, in other cases, idiotic. Using his own knowledge of the local transit system, he was able to reduce the overall travel time significantly.
So what does this mean? Herhold suggests that the VTA trip planner may still be a work in progress. That's a fair assumption. It will likely need to be tweaked to better adjust for the "realities" of public transportation. For 95% of the requested trips, it probably works just fine. When asked to map out times and routes for more complex trips, it may not provide the best solution.
I have the same experience with MapQuest. About nine times out of 10, it provides an accurate, efficient route from Point A to Point B. The other 10% of the time, I take another route based on my own understanding of the freeway systems and surface streets here in Los Angeles. It's still an excellent resource.
At the end of his column, Herhold suggests that many people will be tempted to choose "Drive There" as the best option provided by the trip planner. That will depend more on the dependability, efficiency and customer-friendliness of the transit system than it will on the intelligence of the trip planner.
Thanks for listening.
