Nowadays, both travel guidance systems and traffic signal control systems are quite common for urban traffic management. In order to achieve collaborative effect, different models had been proposed in the last two decades. In recent years, with the development of variable message sign (VMS) technology, more and more VMS panels are installed on major arterials to provide highly visible and concise graphs or text messages to drivers, especially in developing countries. To discover drivers’ responses to VMS, we establish a drivers’ en route diversion model according to a stated-preference survey. Basically, we proposed a cooperative mechanism and systematic framework of VMS travel guidance and major arterials signal operations. And then a two-stage nested optimization problem is formulated. To solve this optimization problem, a simulation-based optimization method is adopted to optimize the cooperative strategies with TRANSIMS. The proposed method is applied to the real network of Tianjin City comprising of 30 nodes and 46 links. Simulations show that this new method could well improve the network condition by 26.3%. And analysis reveals that GA with nested dynamic programming is an effective technique to solve the optimization problem.

“…Likewise, the effects of displaying BTS messages pertaining to state move-over laws or warnings about possible animal crossings have had a very limited effect on speeds (13,14). However, other studies suggest that messages discouraging cell phone use or tailgating may yield some changes in those types of behaviors (3,15,16). The effectiveness of BTS messages on DMS also depends on drivers being able to understand the message.…”

Many agencies use dynamic message signs to display behavioral traffic safety (BTS) messages (e.g., CLICK IT OR TICKET, DONT DRINK AND DRIVE). However, little guidance exists on how best to design and display such messages on those signs. In this paper, the results of a human factors laptop-based study are described, which examined how well drivers can read and interpret BTS messages while simultaneously attending to a secondary control task similar to how drivers must operate their vehicle while simultaneously reading road signs. The study results indicated that displaying BTS messages that include humor, wit, or pop culture references could have adverse consequences on driving behavior for motorists who are unable to correctly interpret the safety topic of those messages. The results also indicated that BTS messages should only address a single safety topic. The length of the BTS message should be kept to 16 words or fewer in low to moderate driver workload environments; in high driver workload environments, BTS messages should be limited to 11 words or fewer.

This study developed a set of pictograms for lane control systems, to provide additional information to drivers on weather and traffic incidents. The results suggest that in the design of traffic signs, it is important to consider local context and not simply adopt standards and practices that are developed elsewhere. The differences in the social and cultural environments may affect the ease of reading and comprehension by local drivers. However, the study also showed that not all locally developed signs were rated higher for their ease of reading than others.. Since some design characteristics are more salient, whereas others tend to be more dependent on the local context, it is important to conduct simple experiments and exploratory research to find the optimal designs to be used.
