Usha Jacome

Senior Traffic Engineer

Usha has worked as a traffic engineer with nineteen years’ experience in traffic and transport modelling, focusing on strategic and micro-simulation modelling, with particular expertise on major toll road projects. Usha has been involved in a diverse range of Highway and Public Transport modelling projects in the U.K. and Australia for both the public and private sectors. Usha is an experienced user of PARAMICS traffic simulation program and has specialised in traffic demand and patronage forecasting using strategic modelling software packages including, EMME and TRIPS.

For the past four years, Usha has worked as an advisor to the NSW Government, focused on demand forecast for major projects with an understanding of demand, network and toll choice modelling.  This work has seen Usha become an integral part of planning for the Sydney Motorway Network, including the three stages of WestConnex and the more recent investigations into connecting spurs and motorways.

Usha has a comprehensive knowledge of both RMS process and Government expectations in relation to the development and delivery of major infrastructure projects and in particular, the community expectations and required standards relating to major project traffic modelling and impact assessment.

Usha has supported the development of both business cases and environmental impact assessments for both the WestConnex projects as well as the M4 Smart Motorway.  This was invaluable support, with trusted client-side traffic expertise made available to Roads and Maritime Services during a period of peak demand and internal staff shortages. She has proven ability to facilitate effective working interfaces with clients and other professions leading to successful project outcomes.  Usha has become seen as a valuable pair of hands, that RMS employees can rely upon to provide sound and technical advice, when internal resources are unavailable.

  • ITAP 22, 42 and 43
  • M12 Motorway – Traffic Modelling Lead
