The 23-year-old bus driver, who had fallen asleep at the wheel after a night of partying, failed a drugs test at the scene.
Woolwich Crown Court heard that Asolo-Agogua got his driving licence in January 2023 and became an Arriva bus driver a year later.
In his short spell as a bus driver numerous complaints were made about his driving – including occasions when he damaged the bus by hitting stationary vehicles or bus stops.
He was briefly suspended following an incident in May when he stopped too abruptly, causing a child passenger to fall on the floor.
However, he was given “the benefit of the doubt” and his suspension was lifted a short time later.
A spokesperson for TfL said: “Our thoughts remain with the family and friends of Ada Bicakci who was killed in a bus collision in Bexley. This was a truly horrific incident that has devastated a family.
“Martin Asolo-Agogua, through his dangerous and selfish behaviour, has caused unimaginable loss and suffering, and his actions were appalling.
“We expect the highest standards from bus drivers and operators servicing London’s bus network and customers.
“Driving a bus is a significant responsibility and safety is paramount. We will ensure that everything that is learned from this incident is acted on to prevent this ever happening again.”

Gregory Fishwick, defending Asolo-Agogua, said: “My client only hopes that if anything comes from this, it’s a stern warning that people should not drive if they are in any way fatigued.”

Bora said: “We seek not just justice for our daughter but a safer future for everyone.”
He said knowing that similar incidents lie around the corner causes him as much pain as losing his daughter.
“We hope road death becomes history,” he said.
