• ### Reducing local traffic emissions at urban intersection using ITS countermeasures

Publication Year: 2013, Page(s):78 - 86
| | PDF (687 KB)

In many countries traffic emissions have significantly increased during the last two decades because of the increased number of vehicles. As such, traffic emissions have become the main source of air pollution in urban areas, where breaches of the EU limit values frequently occur. To reduce these emissions, local traffic measures can be implemented complementary to regional and national measures. ... View full abstract»

• ### Dilemma zone avoidance development: an on-board approach

Publication Year: 2013, Page(s):87 - 94

The dilemma zone (DZ) has been discussed in traffic engineering over four decades, because it is positively correlated to potential accidents. The dynamic feature of DZs is indeed difficult resolved and handled only by traffic signal control. This study aims to develop a series of onboard algorithms for DZ avoidance and warning. Three algorithms, DZ estimation, DZ prediction and warning selection ... View full abstract»

Publication Year: 2013, Page(s):114 - 121
Cited by:  Papers (1)
| | PDF (576 KB)

Calibrated simulation models taking into account adverse weather conditions can be used to optimise traffic management strategies, such as speed adaptation and signal timing optimisation. On snowy road conditions, car-following behaviour changes because drivers tend to accelerate more slowly, increase their following distance and drive with lower speeds. Such changes results in lower saturation fl... View full abstract»
