High traffic volume by motorised individual traffic (MIV), demands to higher road safety and effective and sustainable using of street infrastructure need modern procedures of the traffic influencing and information. Dynamic signalling systems (DSS) offer a suitable possibility for this.
Research project will examine which DSS on primary distributors are suitable for traffic flow, operationally, technically and economically feasible. Possible interactions with static or individual routing and information systems will be considered. The evaluation of national and international experiences will form an important basis. With the investigation the demands of traffic-participants, planning and executive offices as well as other affected persons will be considered. DSS on primary distributors can be suitable in towns, suburban and outside of built- up areas. They receive an increasing importance as operation means for dynamic traffic management at cantonal level. The research project treats with priority traffic-technical and operational aspects of the possible DSS - applications.
The aim of the research project is to examine possibilities and effects of dynamic signalling systems (DSS) for motorised individual traffic on primary distributors.
The different systems are listed and their areas of application are shown. The different demands of traffic-participants, planning and executive offices as well as other affected persons are analysed and valued according to the criteria road safety, traffic flow and economic efficiency (cost – benefits).
DSS must be conforming to legal and rules standards concerning contents and creation of signals and marks. Investigation considers this interaction between dynamic and static equipment to the traffic influencing/-information. In result of that coherent defaults will be given for formal design and also application and operation criteria’s of DSS on primary distributors for whole Switzerland.
The purpose of the research project exists in the creation of rule bases.
1. National and international literature and research project including dynamic signaling to particular HVS of topics relevant Swiss laws and standards; Mail - survey of selected cantons and towns to applications and cost dynamic signaling..
2. Cataloging of dynamic signaling following application types:
- Dynamic variable routing
- Dynamic route guidance (modal, intermodal)
- Dynamic parking guidance systems
- Dynamic regulation signals
- Dynamic danger signals
- Display driven speeds
- Standardized information about traffic delays
- Event information and impact on traffic
This point includes the definitions.
3. Development of transport planning and traffic engineering requirements for dynamic signaling with qualitative evaluation based on the criteria traffic safety, traffic flow and profitability
4. Investigation operationally. The organizational framework and technical systems, e.g.
(de-) central operation, involvement in regional and national traffic management, functional
description of equipment, interaction with Internet-based information and navigation devices
5. Elaboration of requirements for the content and form of dynamic signals
6. Examination of two practical applications (urban parking guidance system, dynamic signaling on HVS as a measure in the cantonal traffic management)
7. From the results of points 1 to 6 data sheets are developed.
8. Development of a standard approach
9. Creation of the research report incl. Half-yearly interim reports and presentations
The research project analyzed the national and international state of the art and future applications in the dynamic signaling the MIV on major roadways (HVS). From this a catalog will be created by use types and areas of application / limits for the first time.
The expected effects of the dynamic signaling on traffic safety, traffic flow including environmental and cost-effectiveness are evaluated qualitatively for each system. This is done from the perspective of road users, the responsible authorities and taking into account other affected (residents, non-motorized traffic).
For the decision of the responsible authorities are concrete indications to the cost - benefit - analysis given. This should also take into account the growing interaction between the increasingly used individual Web page or navigation devices based information and the collective roadside information by dynamic signaling.
There was created standardized specifications for the planning and operation in Switzerland.
With the use of dynamic signaling significant gains in safety and quality of the traffic flow can be achieved on the road. On traffic-situations will respond quickly and efficiently and with foresight.
The beneficiaries are mainly road users here. Uniform application recommendations for Switzerland to increase the user acceptance.
For operators, a practical planning aid is provided. The use and operating criteria will be created to help to achieve positive economic effects. The deployment of personnel for operational duties, particularly in recurring events can be reduced.
The sustainable use of existing infrastructure will be strengthened and protected resources.
