Be aware of your surroundings, and avoid making sudden movements. These were from the Vedanta-Foxconn joint venture, Singapore-based IGSS Ventures and global consortium ISMC, which counts Tower Semiconductor (TSEM.TA) as a tech partner. Begin to slow down gradually so that you can exit the expressway at the posted speed limit. There are a few things to consider when trying to decide whether it is better to stay in the right lane or the left lane when getting off an expressway. However, due to the influence of terrain, geology, land use restrictions, and an increase in road network density due to the construction of new roads, the distance between the tunnel and the exit of the main line interchange in front is often too small. To analyze the setting method of exit advance guide signs in mountainous expressway tunnelsafter considering the influence of tunnel clearance on the layout size and information setting of exit advance guide signs12 types of exit advance guide signs with different information combinations are proposed based on information quantification theory, and signs with different combinations of information are evaluated by an E-Prime simulation experiment and subjective load technology, laying a theoretical foundation for their setting. However, the research on guide signs in tunnels that are limited by the boundary is less, and the theoretical guidance is relatively weak. If you are unsure, it is always better to err on the side of caution and wait until there is no traffic coming up behind you. Visual workload contributes to human errors in road accidents and potentially adverse incidents. The place names were all from the mountainous areas in China and contained no uncommon characters. This sign is typically placed a few hundred feet before the actual merge lane begins. The results are the following. It is important to plan ahead so that you know which exit you are needing to take and how far down the road you must travel in order to reach it. This is because you will be cutting off other drivers who are already in the left lane. An example of data being processed may be a unique identifier stored in a cookie. Therefore, when making the video, the vehicle drove at a constant speed of 80 km/s from 123.34 m in front of the exit advance guide sign in the left or right lanes and ended after passing the sign. This will give you time to get up to speed and avoid having to make a last-minute lane change. https://doi.org/10.1371/journal.pone.0281842.s001, https://doi.org/10.1371/journal.pone.0281842.s002, https://doi.org/10.1371/journal.pone.0281842.s003, https://doi.org/10.1371/journal.pone.0281842.s004, https://doi.org/10.1371/journal.pone.0281842.s005, https://doi.org/10.1371/journal.pone.0281842.s006, https://doi.org/10.1371/journal.pone.0281842.s007. In a deal that bypasses US sanctions and gives a lifeline to its power grid, Iraq agreed to swap oil for gas from Iran. For more information about PLOS Subject Areas, click Many exits in the Northeastern states which currently or formerly used sequential numbering schemes had these directional abbreviations, but most have converted to A-B schemes. Emotions 5.8. Consistent application of this sign at each exit is important. How do you know when you are getting close to an exit? Safety Belts 5.10. Most studies have focused on the relationship between visual load and reaction time. 2023 Texas Defensive Driving Test Answers UNIT 6, CHAPTER LEVEL 6 Driving behavior in expressway tunnels is more complicated than in common roadbed sections because of differences in illuminance, visual range, speed perception, and reaction time. However, there is no unified standard for the quantification and threshold calculation of traffic sign information. Signal at least four seconds before you change lanes. Continue with Recommended Cookies. Florida Driver Handbook | Expressway Driving 2. e0281842. Table 3 shows the amount of information contained by each element. Save my name, email, and website in this browser for the next time I comment. In a highway tunnel exit to an interchange with a small spacing section, the interchange exit advance guide sign provides important information to guide drivers to leave the main line safely and smoothly. A total of 38 subjects were recruited to participate in the experiment, consisting of 65.8% males and 34.2% females, 57.9% with driving experience, and 42.1% with no driving experience. The company said it had worked with Vedanta for more than a year to bring "a great semiconductor idea to reality", but they had mutually decided to end the joint venture and it will remove its name from an entity that is now fully owned by Vedanta. The deadline was then extended to 2008. 5. The average reaction time of drivers recognition of exit advance guide signs under different information combinations is shown in Table 10, and the distribution of recognition reaction times is shown in Fig 8. https://doi.org/10.1371/journal.pone.0281842.g008, https://doi.org/10.1371/journal.pone.0281842.t010. Shannon [39], the founder of information theory, defined information as an uncertain description of the state of motion or existence of things, and mathematically defined the amount of information as the logarithm of the occurrence probability of random events with negative values, The remaining 2.1 miles (3.4km) of the highway remained as KY 9007. where Hi(X) is the amount of information of element i of traffic engineering facilities, in bits. After completing the experiment, an assistant asked each subject to complete a subjective workload assessment technique (SWAT) questionnaire and an evaluation questionnaire. Once you have exited the expressway, make sure to check your mirrors and blind spots again before you start driving on the surface streets. First, you want to make sure that there is no traffic coming up behind you. Better to take a few extra minutes than to put yourself and others in danger. At the same speed as traffic already on the expressway for subscribers! Kim [17] found that a combined visual and auditory alarm was most effective in terms of drivers cognitive loads. Wisconsin has exit numbers on the freeway and expressway portions of US 10, US 12, Wisconsin Highway 16 (WIS 16), WIS 26, WIS 29, WIS 30, WIS 64, US 41, US 45, US 51, US 53, Wisconsin Highway WIS 145, and US 151. In 2011, the Natcher Parkway was extended 2.1 miles (3.4km) to terminate at Scottsville Road (US231). The weight of each element is shown in Table 7. https://doi.org/10.1371/journal.pone.0281842.t007, According to Table 7, it can be obtained that the weights of components such as highway number and exit are relatively low, and place name has the largest weight, which means it is indispensable. broad scope, and wide readership a perfect fit for your research every time. However, there are some general tips that may be useful for those wanting to get off an expressway. The setting is shown in Fig 6. https://doi.org/10.1371/journal.pone.0281842.g006. No, Is the Subject Area "Roads" applicable to this article? Finally, the best combination form of guide signs is comprehensively determined according to the subjective load of drivers, the recognition time of signs, the amount of sign information and the accuracy of recognition signs. We used E-Prime 3.0, an integrated experimental software system for psychological behavior research, to conduct experiments on the influence of exit advance guide signs on drivers driving load. He has a Bachelor's degree in Business Administration and has gained numerous awards for his articles over the years. Expressway: Before entering the expressway: Check traffic. Similarly, the US54 freeway from El Paso to the New Mexico state line also uses sequential exit numbering. In long tunnels, tunnel lighting influences not only visual performance but reaction time. Maintain a Steady Speed: Do not move in jerks. Once on the exit ramp, you must continue to decelerate within the lane markings and maintain adequate spacing We declare that no author receives salary from the funder. If possible, it is also a good idea to take a look at a map of the area surrounding the expressway exit to get an idea of the roads and traffic patterns. There is no definitive answer to this question as it depends on individual circumstances. With analysis you won't find anywhere else, we break down the biggest stories of the day and speak to top guests who have skin in the game. The most important thing to keep in mind is the reason you are getting off the expressway. Yu [37] adopted the strict definition of information from Shannons information theory and provided procedures for quantifying the effective provision of traveler information. However, the existing research mainly focuses on the design of guide signs for ordinary road sections that are not limited by the boundary space, including urban road intersections and diversion sections of expressways.
