Several footbridges along the city had camera crews record traffic flow on different lanes - an exercise that kicked off on Monday, February 20,
The crew placed small cameras on different footbridges early in the morning and late during rush hour.
Among the areas that contained a small camera crew included a footbridge near West End building along Waiyaki Way, and several footbridges along Thika Road and Mombasa Road.
During that period, the crew recorded motorists, passengers and other road users.
Speaking to Kenyans.co.ke, a security attendant manning a footbridge near West End apartment along Waiyaki Way stated that the crew was deployed to gather information to help the government audit the roads.
He added that the data gathered was critical in helping the government and other stakeholders carry out a risk assessment on the busy highways.
The security attendant insisted that the collected information had been used to make relevant road safety decisions.
Defending his sentiments, the security attendant indicated that wire mesh and guards were erected along Waiyaki after school-going children were exposed to speeding vehicles while crossing the road.
"It is not the first time they are coming. They are deployed to help the government gather information to help in risk assessment.
"You remember when the road was expanded after Nairobi Expressway completion, people had difficulties crossing the road. That data and footage helped inform the decision to erect wire mesh and guard rails along Waiyaki Way," he stated.
He insisted that the crew was deployed on refurbished, expanded and newly built roads across the city.
"It basically helps the government gather information to help avert cases of road mishaps or even designs exposing people to danger," he insisted.
He, however, did not name the company deployed to gather the information on behalf of the government.
An insider from Kenya National Highways Authority (KeNHA) declined to comment on other functions and roles assigned to the crew collecting data.
Besides using cameras, the government and other research companies assign individuals task to count and tabulate data on different vehicles in the country.
In a group of five or six, the teams are deployed near roundabouts and junctions to collect motorists' information.
However, official data on road safety is normally released by the National Transport and Safety Authority (NTSA) in collaboration with the Ministry of Roads.
NTSA's data helps the government lay out frameworks for road safety countrywide.
