Portsmouth Council in the United Kingdom has
recently started using BlipTrack sensors to collect information on traffic
patterns, shortest routes, and travel times. The sensors are laid out
throughout the city's most congested roads and the information is sent via
Bluetooth and Wifi. I think one of the most important parts mentioned in the
article is that the information collected by the sensors is being used to help
determine needed road work. The article states "the information collected
is so far being used primarily within the council for strategic planning tasks,
such as identifying problem areas, learning about the capacity of existing
roads..." The council can look at the roads that see the most traffic and
examine the roads to determine if work can de done to help reduce traffic.
These sensors are allowing the council to see where most problems occur on the
road, so that they can address those roads first. The second component I would
like to analyze is how the sensors are collecting information that is useful to
the economy and the environment. The article states that the sensors collect
information, then the information is analyzed by experts, and then the council
determines the shortest traveling routes. This could allow consumers to cut
their travel times, save on gas, and therefore reduce the total carbon emission
from their vehicles. A third component I would like to look further into is how
the sensors are collecting information that is useful for everyday use. The
sensors collect info on traffic on certain roads, which could help people obtain
a more realistic travel time and information on what days roads see the least
amount of traffic, which is useful for determining the optimal time for working
on the roads.
I do believe that there were some major factors
overlooked in this article. First off, the article mentions that soon the public
we be able to access this data on a website, but will the public be able to
access the data from their phones too? Or will they have to go onto the site
from their computers at home? This is very important because if people cannot
access the site while they are driving, then they cannot access the information
when they need it the most. I also think that the article didn't discuss
whether or not the sensors can be used in small towns too. The only mention of
these sensors are in more urban areas. I live in a small town of about 20,000
people, but I still know that on a Saturday I could run into 20 minutes of
traffic. And the third factor overlooked was the cost of these sensors. I think
it is extremely important to take into account how much these sensors cost. If
they're cheap, then I think this could benefit a lot of areas. But if it costs
hundreds of thousands of dollars, I would rethink how vital these sensors are.
