By way of example, consider other cities that are government centres, highly touristic, and densely populated in their govt/tourist areas. Traffic might fall into three broad categories. Local traffic that is shaped by commuters into and out of the govt and related offices and facilities. This will be a heavy mix with lots of public transit use and, in the case of London, increasing cycle traffic. Mostly, this translates into pedestrian traffic at certain times of day and concentrated around office hours.
Another category would be the flow of tourists - visitors both domestic and foreign. That translates into coaches and quite a bit of public transit use - which then are feeders of pedestrians around the big tourist sites. London is a good walking city for visitors. At all times of day and night - all week long. On the EMBANKMENT, coach parking has always been a big deal - especially before and during the changes to the lanes. When coaches are not in those spots, other traffic tends to make use of the kerbside.
A third board category would be 'through-traffic' which would be mixed - commuters getting from A to B, tourists same, and locals going about their normal business. This would be traffic not to EMB destinations. I think that cabbies are a good example of this. Cut thru the best routes between fares - and for the best fares. This was expressed fairly strongly in the court cases regardinng the bike-lead changes to lanes and parking in the EMBANKMENT area generally. Some of this is specific to the bounds of Q pics.
Look at all the London pics, but especially EMB, and consider these types of traffic. Does the pictorial evidence meet your expectations? If not, are the expectations off or the activity within the camera frame is off?
To keep this as simple as we can, maybe spend some time reviewing vids of traffic through the EMBANKMENT. Just observe and see what might provide a lead. An example might be the presence of cabs. Or coaches. Or motorbikes, as we have discussed. The parking might not match the representation in the street flow.
I have noticed that at times, during daylight hours, the TATT and HISP have not been very busy. Thot it was just timing. But then it is common enough in the many vids online that it makes me second guess my first impression.
I do think that we've narrowed down the time range successfully. And I do think the MAR 5 2014 bookend is gud but not precise for reasons mentioned upbread. To resolve that bookend with lunar/tidal info just may need to use brute force and search for the evidence in pics and vids during MAR-APR 2014.
