FHWA’s weather guidelines for road users

The tremendous growth in the amount of available weather and road condition information—including devices that gather weather information, models and forecasting tools for predicting weather conditions, and electronic devices used by travellers — has led the Federal Highway Administration (FHWA) to develop effective and specific guidelines for communicating road weather information in a way that is consistent with what travellers need, want, and will use when making travel decisions.

The tremendous growth in the amount of available weather and road condition information—including devices that gather weather information, models and forecasting tools for predicting weather conditions, and electronic devices used by travellers — has led the 2410 Federal Highway Administration (FHWA) to develop effective and specific guidelines for communicating road weather information in a way that is consistent with what travellers need, want, and will use when making travel decisions.

This project, Testing and Evaluation of Preliminary Design Guidelines for Disseminating Road Weather Advisory & Control Information, builds upon the earlier Human Factors Analysis of Road Weather Advisory and Control Information project which was initiated to assist transportation officials in communicating both pre-trip and enroute road weather information effectively, consistently, and timely to meet the needs of travellers for different weather conditions and travel scenarios. This earlier project resulted in preliminary guidelines.

For the current 122-page publication, these preliminary guidelines were disseminated to a broad group of transportation and road weather officials for review and use.

These reviewers included staff from private agencies and State Department of Transportation (DoT) staff working at traffic management centres. Evaluation of the guidelines followed through end user surveys, on-site interviews and discussions, and application of the preliminary guidelines to assess their suitability and effectiveness for traffic operations. Valuable feedback provided by these end users was used to modify the preliminary guidelines and develop the revised guidelines.

    Simply banning cars in parts of major cities will not necessarily greatly improve the air quality over time, a new report has found. The answer for cutting carbon emissions is to get the right balance of private and public transportation along with infrastructure developed to sustain the mix, according to the International Transport Forum (ITF), a think tank within the Organisation of Economic Cooperation and Development (OECD). The ITF evaluated the potential impact of transport policies on urban carbon

    With a national UK election looming next month, a future government must make road safety a top priority, said the Institute of Advanced Motorists (IAM). Half of motorists in a recent survey of 2,156 people, and conducted IAM in March, said the current administration has not given the issue as much attention as is needed. The number one issue that the government should be focussing on, according to 70% of respondents, is the reduction of the number of potholes. The backlog of repairs now tops more

    A researcher based in Canada is carrying out a research project in the form of a survey assessing the safety risk posed by wildlife to drivers. The risk posed by wildlife to those travelling in vehicles can be severe in some areas and evaluating data can be important for assessing risk levels and awareness of risk levels amongst road users. There is the potential for serious injury or even death in the event of crashes with large animals or at high speeds. Meanwhile a driver avoiding an animal in the roadwa
