Purpose: The aim of this paper is (i) Estimation of total emission during idling of vehicles (ii) Validation of emission results from real-world data.

Design/methodology/approach: In this paper, a case study of the Ashram intersection in Delhi has been selected in order to measure the emissions of vehicles during idling delays by customising the emission model MOVES2010b.

Research limitations/implications: Different intersections will need different input data for estimates.

Findings: It was found that 3.997 mg/m³ of hydrocarbon, 1.82 mg/m³ of NOx, and 17.688 mg/m³ of carbon monoxide is emitted from the cars, trucks and buses respectively at Ashram intersection in one day. As there are 600 intersections throughout Delhi, a total of 2398.055 mg/m³ of hydrocarbon, 1087.068 mg/m³ of NOx, and 10612.612 mg/m³ of carbon monoxide is emitted from cars, trucks and buses in a day in all of Delhi.

Originality/value: There is very little knowledge of modelling emission during idling delays for vehicles.
