The Simulation of the Effects of the Traffic Management Trial Amsterdam
H Taale, CTN, Ministry of Transport, NL
The traffic management trial Amsterdam aims to determine the effects of regional, coordinated traffic management. The Regional Traffic Management Explorer was used to get an indication of the effects beforehand.
The Regional Traffic Management Explorer (RTME) was developed in order to facilitate the sustainable traffic management (STM) method. The STM method consists of clearly defined steps to develop and implement a consistent and accepted (in terms of political objectives) set of traffic management measures. It that can be summarised as: defining policy objectives, assess current situation, determine bottlenecks and create solutions. This process helps to develop a network vision based on policy objectives, shared by all participating stakeholders.
The Traffic Management Trial Amsterdam is mend to study in a real-life situation the effects of network-wide, coordinated traffic management on a regional scale. The trial uses the STM process to determine the measures. The measures vary from adjustment of weaving sections to information using a new type of VMS and ramp metering.
The RTME is a sketch and calculation tool that supports the steps needed for STM and makes it possible to determine the effects of proposed traffic management services and measures. These effects can then be compared to the formulated policy objectives or other sets of measures. The RTME was used to study the effects of all the measures in the trial on the traffic flows and the traffic situation in the network. It was shown that the proposed measures have positive effects on network delay and on travel times. The paper will discuss how the model was used and what the results are. Furthermore, the paper will describe how the RTME will be used in the evaluation study, which will be conducted during the trial.
