| Abstract: | The effects of atrocious weather factors on road operating safety were investigated and the design frequency of atrocious weather was calculated using historical weather data.The safety operating speed models were developed considering sight distance,vehicle head space under various climate and traffic conditions.The models were verified using traffic simulation and the safety road operating speed was provided based on local networks of Highway Bureau in Shanghai. |
