Corrections to “Integrated Urban Traffic Control for the Reduction of Travel Delays and Emissions” [Dec 13 1609-1619]

The corrections given involve
Equations (4)
,
(5)
,
(9)
in the S-model and Equations (13)–(16) in the integrated flow and emission model introduced in
[1]
. For details and extensive proofs of the proposed corrections and modifications, we refer the readers to
[2]
and
[3]
. Moreover, we propose some extensions/modifications to
[1, eq. (9)]
that result in a simple formula that can be used to compute the integral in
[1, eq. (9)]
. Since the S-model was originally introduced in
[4]
, the corrections and modifications given for the S-model in this paper also hold for
[4]
.
