How can you improve traffic flow at highway interchanges using traffic data?

Install Early warning traffic congestion systems on Highways Analyse the traffic patterns to improvising the design / implementation of traffic calming measures

Utilize satellite technologies to create data points showing all relevant events. Review a full year to identify seasonal trends.

where ever possible utilise the existing infrastructure to collect as much traffic data as possible, such as traffic signal detection and Automatic Traffic Counts

Use ATCs or sensors or cameras to identify the various modes (2-wheeler, 4-wheeler, Bus, Truck etc) traffic pattern for typical peak hour of weekday and weekend both. Traffic Density could also be calculated at various sections. This would help identify the bottleneck points and section and give a better clarity on the problem.

Importante que nessa análise haja os modais que trafegam pelas vias, pois isso afeta diretamente no comportamento da via, visando pensar em outras op??es, principalmente em veículos maiores.

A seguran?a viária é essencial no desenvolvimento desses projetos. A visibilidade da via depende do tra?ado, da sinaliza??o e de boas condi??es de ilumina??o. A boa execu??o da manobra depende de um raio mínimo de giro. Ao desrespeitar essas condi??es, acidentes se tornam mais frequentes e fatais para aqueles que utilizam essas estruturas.

Ao identificar o local, é importante reavaliar a infraestrutura, de modo a corrigir eventuais imperfei??es que acabam por colaborar com o congestionamento próximo aos trevos. Será que a rodovia foi projetada para um fluxo muito abaixo do atual?

No projeto do intercambio, aten??o à ilumina??o, pavimento e aspectos ambientais é vital. O equilíbrio entre capacidade, eficiência, seguran?a e custo deve considerar crescimento futuro e mudan?as na demanda. A integra??o harmoniosa na rede viária circundante é essencial.

there are a number of control strategies existing and new to the market SCOOT MoVA these can be configured to provide sustainable traffic priorities thus promoting the use of public transit systems

Essas informa??es precisam chegar de maneira clara para os usuários, de forma simples e eficaz para que haja tempo de a??o e mudan?a de rota.

If using traffic signals, it is essential to use the right method of control for different situations you may encounter at the site. For example, during peak periods, it may be most appropriate to use a fixed-time operation with predetermined stage and offset durations; whereas during off-peak periods, vehicle activated strategies will provide more flexibility and less waiting for users. At night, we have found that reverting to an All Red stage can reduce lone vehicle incidents and reduce the number of times trucks have to stop unnecessarily. This is achieved by using vehicle detection to demand the relevant stage so that it opens up to the approaching vehicle only when it is close to the stop-line, thus slowing but not stopping them.

New world required latest traffic technology. Currently we are using many systems monitoring traffic control but this is not enough to control traffic systems. Need to implement advanced applications. We want to invite IIT, MIT students and talented communities research and providing best solutions in future Traffic solutions.

There could be implementation of active as well as passive control strategies. And in case of any accident (immediate health assistance should reach to the spot with road operator help to clear the traffic) or hindrance in traffic flow road users should be informed ahead of time. So that they get prepared to overcome the bottlenecks.

where possible ensure that the collected traffic data can be integrated directly into the proposed modelling and simulation tools

Modelling is absolutely essential to design a good solution, however, this needs to be undertaken by someone who understands traffic behaviour and also how measures, such as traffic signals, really effect traffic. I have seen many designs that 'vertically' stack waiting vehicles at internal stop-lines because of a lack of understanding of realities involved.

There of bunch of scenario modeling and simulation tool which could help in improving the flow in safety. I would say that trying different scenarios with data integration could potentially compare the different alternatives and leads to the best options to improve the traffic flow.

PTV Vissim is the perfect tool for micro-simulatiom. Traffic operational and safety performance can be done with the help of this tool.

Any traffic model or simulation should be validated for the actual case of scenario. And the efficiency of the model should be higher. With validated model we will get the results of simulation which will replicate the real world situations and we can forecast and predict any situation that may be trouble some in future.

Avec une analyse approfondie avec tous les acteurs concernés pour une plate-forme adéquate qui est un outil de facilitation et de communication pour les usagers. L'étude qui a été menée au préalable avec les principaux acteurs de la ligne du transport doit être publiée à travers les panneaux publicitaires ainsi que les TV et les radios pour la bonne marche des initiatives entreprises.

In certain instances, highway interchanges are positioned at the intersection of two distinct administrative areas, each overseen by separate agencies responsible for controlling the interchange. To achieve optimal traffic flow, it is imperative for the responsible agencies to establish a well-coordinated control system. This involves seamless communication and collaboration between the involved stakeholders, including local municipalities, transportation authorities, and relevant government bodies. Stakeholders must actively engage in the planning, implementation, and maintenance of traffic management strategies.

Stakeholder engagement such as enforcing agencies (traffic police) is very critical as they regulate the traffic flow. Communication between the planners, engineers, and regulators is the key here.

é imperativo engajar proativamente as partes interessadas, abrangendo desde autoridades até comunidades. Estabelecer comunica??o eficaz com operadores rodoviários, engenheiros, reguladores, residentes e outros intervenientes é essencial. A incorpora??o diligente de feedback, preferências e expectativas, aliada à resolu??o atenta de possíveis conflitos, solidifica um processo de planejamento inclusivo e resiliente.

Over and above the active design and system measures, what the data could be used for is understanding how a city could incentivise businesses to open longer. This would not only deal with the short term traffic issues, as different businesses structuring their labour staff in a staggered shift system would mean lower traffic 'peak', but also present the more employment opportunities as more people would be employed in similar positions, just working at different shifts. This scenario could in effect incentivise public transport (in spaces where there is none). Thus not only reducing the rate of private vehicles, but overall traffic

Tomar en cuenta la modernización y crecimiento de la urbanización, puesto que conforme transcurre el tiempo los flujos de tránsito y puntos de concurrencia cambian (centros comerciales, parques, etc.), lo cual influirá en los dise?os iniciales.

build in a robust monitoring and data collection system as part of the design and delivery of the scheme, as this is often an after thought, at least 2% the scheme cost should be considered as monitoring funding

A partir de uma pesquisa origem e destino, é possível entender e compreender os desejos de viagens e, assim, definir estratégias, por meio de diversas ferramentas, que possam melhor o fluxo nos trevos.

é importante que essa análise seja feita e acompanhada diariamente no come?o do projeto para que haja mais possibilidade de melhorias dia a dia.

L'idéologie déposée est le transfert de connaissance. On constate de nos jours qu'il y a assez de véhicules dans le monde et souvent on est entra?né à des flux de trafic routier. Pour une meilleure circulation et fluide on doit avoir une amélioration d'infrastructures routières tout en impliquant les principaux acteurs. L'adoption d'un outil de communication à la TV, radios, et les panneaux publicitaires. De ce fait l'idéal est la vérification des modules et l'instauration de nouvelles règles au sein des auto écoles qui sont habilitées et qui également sont une référence de concours aux codes de la route au départ. L'engagement et les décisions prises doivent être irrévocables pour permettre la suivi du droit. Duralex sedlex

If you are using active measures, such as traffic signals, to control interchange operation, then it is important to go back to validate their operation after the initial commissioning to ensure that the operation is efficient. Driving styles and traffic flows often change after an interchange has undergone upgrades for a variety of reasons, including suppressed demand because drivers were avoiding it previously due to congestion and delays. It is also important to periodically review these sites every few years to ensure their efficiency is maintained over time, traffic patterns can change dramatically over time, so without this congestion can be experienced unnecessarily.

Creio que um dos pontos que n?o est?o nos tópicos é o impacto do crescimento, pois dependendo da regi?o há um crescimento que deve fazer parte dos estudos e bases de análise. Como exemplo regi?es onde o crescimento habitacional ou de negócios tais como prédios, galp?es, Centros de distribui??o e ate mesmo fabricas, podem impactar n?o só no fluxo com também em um nova infra estrutura, com vias secundarias e/ou ate mesmo novos trevos para suportar.

A focus on generalizable and replicable data sources is beneficial as it allows for expansion of ideas to new cases, areas, and situations.

T?o importante quanto pensar em formas de aliviar o fluxo nos trevos, é pensar em alternativas de deslocamento n?o baseadas no transporte sobre pneus. Por exemplo, se há uma grande demanda circulando em algum trecho em quest?o, porque n?o pensar em implantar, uma ferrovia, que poderia atrair parte desse fluxo das rodovias?
