Hi Sachin,

First, you need to be very careful with daily! Are we talking weekends, weekdays, or overall?

Estimation of those using m25 for work

1. Population of london (and surrounding areas)
2. % of commuting population
   1. % commuting during the week
   2. % commuting during weekend (service workers, etc.)
3. % of commuting population not living in central london and not using public transport

​Estimation of those using m25 for leisure

1. Population of london (and surrounding areas)
2. Population segments (age and/or affluence)
   1. % in each group that own a car
   2. # of daily leisure uses for each group (note: You should definitely assume weekend #s are higher)
   3. % of trips that require m25 motorway

Then add the two together :)

Hello,

Completely agree with the proposed approaches but I could have started with a segmentation into 3 buckets

1) People who go to work or come back from work

2) vacationers or people passing through (probably with a peak at Christmas and during summer vacation periods).

3) Road workers (trucks, salespeople, ...)

Best,

David
