The effect of various levels of on-street parking on the operating conditions of traffic stream has been quantified in terms of congestion and level of service. The data obtained from a controlled experiment of on-street parking has been used to model congestion and to estimate level of service characteristics for the traffic flow with zero, low, medium and heavy on-street parking. The quantified congestion at different operating traffic volumes and the corresponding levels of service have been analysed and used as a basis for developing a potential policy for rationalisation of on-street parking on an example urban road.
