It can work. We have the technology. We can find the solution.

The (Public rapid transit) idea can work in singapore, but not the (Personal rapid transit).
ReplyDeleteThe (Personal rapid transit) is too much like a car, causing the same traffic jam.
The ideal attributes of a (Public rapid transit) should have:
+ Priority right of way on road;
+ Electric powered, no driver, computerised;
+ Run on schedule;
+ On demand schedule via SMS;
+ Booking via SMS (if higher demand, the system will respond and deploy another PRT);
+ Capacity : ~ 20 passengers;
+ High frequency during peak hours;
+ affordable.
+ Intra-town service (Long distance by MRT service);
Hi anonmymous
ReplyDeletePlease register with your actual name. It will be nice to discuss this matter with you.
My preference is to have a PRT that serves a town. The pod carries 4 people and operates like a taxi, without a driver.
ReplyDeleteEach town has an average of 200 pod stops, making a total of 4,000 pod stops (if the whole of Singapore is covered). This will be twice the number of bus stops.
I will write more about my concept in a separate paper.

So you're of the opinion that computer controlled vehicles would be just as prone to poor judgement as human driver cars? This simply makes no sense. Take a look at this.
To the contrary, computer controlled vehicles have the potential of being VASTLY more efficient. No needless stops at intersections. No speeding, no accidents. No rubbernecking. No needless accelerations and deccelerations. There's simply no contest.
The ideal capacity is exactly that of the automobile, not 20. When you drive to the grocery store, do all your neighbors go at the same time?

Tan, you said:
ReplyDelete"Each town has an average of 200 pod stops"
Once you have the 200 pod stops, what prevents you from adding another 100?

Hi Gary,
ReplyDeleteThe average distance between the pods stops is 250 m. I think that this is acceptable. The distance is quite short because Singapore is a condensly populated city.
Each pod station adds to the infrastructure cost. By having the optimum number, and not excessive stations, we can keep reduce the construction and operating cost.
Hi Tan,
ReplyDelete250 m is great. Very close together. So how close together would the stops need to be before people could discontinue using the automobile for travel within the city?
