Abstract

The effectiveness of transitional speed zones was reviewed in the province of New Brunswick, Canada, by collecting speed data as vehicles moved through transitional zones. At the onset, a premise of the study was that transitional speed zones might not be effective in reducing mean speeds and might, in fact, increase speed dispersion. Speeds were measured at five locations for sites with transitional zones and at three locations for sites without transitional zones. Data were collected during daylight hours and under good weather conditions. Analysis of the data revealed that signs are not effective in reducing speeds if there is not a corresponding change in highway characteristics. The transitional speed zones were found not to significantly impact the variance in speeds as vehicles traveled from the high speed zone. Overall, results indicate that there are not enough positive impacts associated with the provision of transitional speed zones to justify their use by road authorities.
