Designated police teams will tackle trouble hotspots on the transport network in outer London, if the mayor's £7.5m deal is approved.
More police officers should reassure passengers
Under the plan, the money would fund an extra 375 community support officers to be deployed on a weekly basis.
The teams would focus on fare evasion, anti-social behaviour and criminal activity at transport hubs and schools.
Mayor Ken Livingstone said having more uniformed officers was key to deterring criminals and reassuring passengers.
Intelligence gathered by Transport for London (TfL) and its Transport Operational Command Unit (TOCU) is to be used to identify hot spots in suburban and outer London boroughs.
Change in attitude
The police community support officers (PCSOs) will then be deployed in 'transport teams' to tackle the problem areas.
Mr Livingstone said: "I am proposing that we invest another £7.5m to expand the number of visible uniformed officers on London's transport system.
"These officers, based in suburban areas, will make a real difference to people living or working in outer London."
TfL's Jeroen Weimar said: "We would expect to see a change in the attitudes of the tiny minority of members of the public who cause problems on the transport network.
"These new policing teams provide not only a visible deterrent to those intent on causing trouble, but will also provide reassurance to passengers."
Once the funding has been rubber-stamped it is hoped the officers will be in place early next year.
