Good thing we have lots of veteran cab drivers who have "built-in cerebral GPS."

    For the passengers, this is a hassle. For the drivers, they could get into an accident. For the traffic authorities, they could man these "bermuda triangles" and engage in corrupt practices. For the neighborhood, more accidents and run ins with the authorities (road rage) will mean less security, and real estate property devaluation.

What alternatives can be developed to meet this demand without overstressing residential streets and neighbourhoods- there are huge advantages to developing good public transport systems (here in North America, most are abismal, and traveling or commuting by car is the only realistic option for so many, especially as our cities and rural areas are so spread out). When cities invest in streamlining driving routes instead of investing in a better public transport system, this disrupts our neighborhoods and makes no gains in improving accessibility of the city for young and old people, poorer communities, and of course decreasing emissions. Residents don't always know what to expect either: ]]> 2020-05-31 19:07:34 UTC https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/603581212 Problems now, and later https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/605868265 Considerable effort goes into data gathering to support effective roading investment decisions.  I know how relatively  small changes in driver behaviour can be used to estimate  and predict future road use because I did this for a living a few years back.  One of the important issues is that the temporary , and not so temporary, alterations to route choices can introduce subtle but important signals that can then end up as inputs to a system of Roading Investment Logic that goes on to affect priorities - even to the extent of land/properties being purchased by force of law to accommodate expansions for additional lanes.  There is also some evidence that the knock on effects of drivers being routed into unfamiliar one-way systems etc., increases the net congestion and environmental costs

    Singapore traffic management systems are possibly the most connected in the world. This is how Electronic Road Pricing system works: Citizens owning a car are required to install an In-Vehicle Unit (IU) in the car.
     A cash card is inserted in the IU. When a vehicle passes through an ERP gantry, the amount charged is deducted from the cash card. Based on an optimal speed range of 20-30 km/h on arterial roads and 45-65 km/h on expressways, ERP rates will be adjusted accordingly.
    It is no wonder that ERP system is unpopular with the people of Singapore.
    BUT -- it is part of a system that works.

This article talks about it.

The assumption seems to be that we need cars to move more efficiently through our cities. But should that be the priority? What about quieter routes to cycle on? Safer routes that are lit for people walking alone - Durham station can only be reached on foot up a dark, steep, overgrown path, I believe (there must be a road way in as well though). For a woman trying to get a train, this is ridiculous. I recall also a project being mentioned on the Freakonomics podcast that was building up "beautiful" routes. Should we make it MORE difficult for cars to improve our cities?]]> 2020-06-06 12:05:21 UTC https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/614167418 What´s the second purpose? https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/616861843 Based on some review of the availabe information on the Web the majority of links found mention pros and cons but all of them related to traffic and  mobiles features, also road safety (cons). The point is that is not clear wether a second purpose of data collected or not. Who the benneficiary is? and Why.

    Traffic routing is through traffic apps enable optimization of routes through geographic locations. This optimization leads to lower lead times and or reaching your destination faster than before.
    Cons.
    However these apps are more often than not dependent on cell phones and this can increase the risk of motor vehicle accidents due to distractions from use of these devices.]]>     2020-06-12 22:38:28 UTC https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/624668024     Not yet perfect https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/624735970 The services provided by Google Maps do not encompass details of all possible routes available, especially in rural parts of developing economies such as India.

    Secondly, the condition of the roads/routes, in terms of deterioration or potholes is often not Incorporated when Alternative routes are suggested by Google Maps. Thus, in some situations, the alternative routes suggested might take up much more of the commuter's time than the original 'congested' route]]>     2020-06-13 01:13:05 UTC https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/624735970     https://gadgets.ndtv.com/apps/news/google-maps-virtual-traffic-jam-99-smartphones-berlin-man-2174087 https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/628054338 This is a very specific issue i found, recently one person "fooled" google maps by using 99 smartphones.]]> 2020-06-15 22:32:08 UTC https://padlet.com/moocdeliveryteam/4opkiqqcn9mzn83i/wish/628054338
