Prof. Tiwari has about 25 years of professional experience in the areas of Transport Planning, and Traffic Engineering in India, USA, Bangladesh and African Countries. She has been teaching transport planning and modelling, traffic engineering, geometric design of highways and Transport Economics at graduate and undergraduate level at the Indian Institute of Technology in Delhi since 1990. She have been involved in interdisciplinary research including traffic safety, public transport systems since 1997 as member of Transportation Research and Injury Prevention Programme at IIT Delhi. She has taught short-term courses in Australia, The Netherlands, Iran and South Africa,Thailand and Uganda. She has extensive research experience in dealing with transportation issues of special relevance to low-income countries. These include development of systems and designs that would make transportation efficient, safer and less polluting with a special focus on vulnerable road users and commuters.
